This table defines the mapping of character codes to the glyph index values used in the font. It may contain more than one subtable, in order to support more than one character encoding scheme.

Is true for symbol font encoding.

Initializes a new instance of the class.

This table gives global information about the font. The bounding box values should be computed using only glyphs that have contours. Glyphs with no contours should be ignored for the purposes of these calculations.

This table contains information for horizontal layout. The values in the minRightSideBearing, MinLeftSideBearing and xMaxExtent should be computed using only glyphs that have contours. Glyphs with no contours should be ignored for the purposes of these calculations. All reserved areas must be set to 0.

The type longHorMetric is defined as an array where each element has two parts: the advance width, which is of type USHORT, and the left side bearing, which is of type SHORT. These fields are in font design units.

The vertical Metrics table allows you to specify the vertical spacing for each glyph in a vertical font. This table consists of either one or two arrays that contain metric information (the advance heights and top sidebearings) for the vertical layout of each of the glyphs in the font.

This table establishes the memory requirements for this font. Fonts with CFF data must use Version 0.5 of this table, specifying only the numGlyphs field. Fonts with TrueType outlines must use Version 1.0 of this table, where all data is required. Both formats of OpenType require a 'maxp' table because a number of applications call the Windows GetFontData() API on the 'maxp' table to determine the number of glyphs in the font.

The naming table allows multilingual strings to be associated with the OpenTypeTM font file. These strings can represent copyright notices, font names, family names, style names, and so on. To keep this table short, the font manufacturer may wish to make a limited set of entries in some small set of languages; later, the font can be "localized" and the strings translated or added. Other parts of the OpenType font file that require these strings can then refer to them simply by their index number. Clients that need a particular string can look it up by its platform ID, character encoding ID, language ID and name ID. Note that some platforms may require single byte character strings, while others may require double byte strings. For historical reasons, some applications which install fonts perform Version control using Macintosh platform (platform ID 1) strings from the 'name' table. Because of this, we strongly recommend that the 'name' table of all fonts include Macintosh platform strings and that the syntax of the Version number (name ID 5) follows the guidelines given in this document.

Get the font family name.

The OS/2 table consists of a set of Metrics that are required in OpenType fonts.

This table contains additional information needed to use TrueType or OpenTypeTM fonts on PostScript printers.

This table contains a list of values that can be referenced by instructions. They can be used, among other things, to control characteristics for different glyphs. The length of the table must be an integral number of FWORD units.

This table is similar to the CVT Program, except that it is only run once, when the font is first used. It is used only for FDEFs and IDEFs. Thus, the CVT Program need not contain function definitions. However, the CVT Program may redefine existing FDEFs or IDEFs.

The Control Value Program consists of a set of TrueType instructions that will be executed whenever the font or point size or transformation matrix change and before each glyph is interpreted. Any instruction is legal in the CVT Program but since no glyph is associated with it, instructions intended to move points within a particular glyph outline cannot be used in the CVT Program. The name 'prep' is anachronistic.

This table contains information that describes the glyphs in the font in the TrueType outline format. Information regarding the rasterizer (scaler) refers to the TrueType rasterizer.

Specifies the flags of AcroForm fields.

If set, the user may not change the value of the field. Any associated widget annotations will not interact with the user; that is, they will not respond to mouse clicks or change their appearance in response to mouse motions. This flag is useful for fields whose values are computed or imported from a database.

If set, the field must have a value at the time it is exported by a submit-form action.

If set, the field must not be exported by a submit-form action.

If set, the field is a pushbutton that does not retain a permanent value.

If set, the field is a set of radio buttons; if clear, the field is a checkbox. This flag is meaningful only if the Pushbutton flag is clear.

(Radio buttons only) If set, exactly one radio button must be selected at all times; clicking the currently selected button has no effect. If clear, clicking the selected button deselects it, leaving no button selected.

(Radio buttons only) (PDF 1.5) If set, a group of radio buttons within a radio button field that use the same value for the on state will turn on and off in unison; that is if one is checked, they are all checked. If clear, the buttons are mutually exclusive (the same behaviour as HTML radio buttons).

If set, the field may contain multiple lines of text; if clear, the field’s text is restricted to a single line.

If set, the field is intended for entering a secure password that should not be echoed visibly to the screen. Characters typed from the keyboard should instead be echoed in some unreadable form, such as asterisks or bullet characters. To protect password confidentiality, viewer applications should never store the value of the text field in the PDF file if this flag is set.

(PDF 1.4) If set, the text entered in the field represents the pathname of a file whose contents are to be submitted as the value of the field.

(PDF 1.4) If set, the text entered in the field will not be spell-checked.

(PDF 1.4) If set, the field will not scroll (horizontally for single-line fields, vertically for multiple-line fields) to accommodate more text than will fit within its annotation rectangle. Once the field is full, no further text will be accepted.

(PDF 1.5) May be set only if the MaxLen entry is present in the text field dictionary (see "Table 232 — Additional entry specific to a text field") and if the Multiline, Password, and FileSelect flags are clear. If set, the field shall be automatically divided into as many equally spaced positions, or combs, as the value of MaxLen, and the text is laid out into those combs.

(PDF 1.5) If set, the value of this field shall be a rich text string (see Adobe XML Architecture, XML Forms Architecture (XFA) Specification, version 3.3). If the field has a value, the RV entry of the field dictionary ("Table 228 — Additional entries common to all fields containing variable text") shall specify the rich text string.

If set, the field is a combo box; if clear, the field is a list box.

If set, the combo box includes an editable text box as well as a drop list; if clear, it includes only a drop list. This flag is meaningful only if the Combo flag is set.

If set, the field’s option items should be sorted alphabetically. This flag is intended for use by form authoring tools, not by PDF viewer applications; viewers should simply display the options in the order in which they occur in the Opt array.

(PDF 1.4) If set, more than one of the field’s option items may be selected simultaneously; if clear, no more than one item at a time may be selected.

(PDF 1.4) If set, the text entered in the field will not be spell-checked. This flag is meaningful only if the Combo and Edit flags are both set.

(PDF 1.5) If set, the new value shall be committed as soon as a selection is made (commonly with the pointing device). In this case, supplying a value for a field involves three actions: selecting the field for fill-in, selecting a choice for the fill-in value, and leaving that field, which finalizes or "commits" the data choice and triggers any actions associated with the entry or changing of this data. If this flag is on, then processing does not wait for leaving the field action to occur, but immediately proceeds to the third step.This option enables applications to perform an action once a selection is made, without requiring the user to exit the field. If clear, the new value is not committed until the user exits the field.

(Required) The type of PDF object that this dictionary describes; must be Font for a CIDFont dictionary.

(Required) The type of CIDFont; CIDFontType0 or CIDFontType2.

(Required) The PostScript name of the CIDFont. For Type 0 CIDFonts, this is usually the value of the CIDFontName entry in the CIDFont program. For Type 2 CIDFonts, it is derived the same way as for a simple TrueType font; In either case, the name can have a subset prefix if appropriate.

(Required) A dictionary containing entries that define the character collection of the CIDFont.

If the value is a stream, the bytes in the stream contain the mapping from CIDs to glyph indices: the glyph index for a particular CID value c is a 2-byte value stored in bytes 2 × c and 2 × c + 1, where the first byte is the high-order byte. If the value of CIDToGIDMap is a name, it must be Identity, indicating that the mapping between CIDs and glyph indices is the identity mapping. Default value: Identity. This entry may appear only in a Type 2 CIDFont whose associated True-Type font program is embedded in the PDF file.

Predefined keys for cross-reference dictionaries.

(Required) The type of PDF object that this dictionary describes; must be XRef for a cross-reference stream.

(Required) The number one greater than the highest object number used in this section or in any section for which this is an update. It is equivalent to the Size entry in a trailer dictionary.

(Optional) An array containing a pair of integers for each subsection in this section. The first integer is the first object number in the subsection; the second integer is the number of entries in the subsection. The array is sorted in ascending order by object number. Subsections cannot overlap; an object number may have at most one entry in a section. Default value: [0 Size].

(Present only if the file has more than one cross-reference stream; not meaningful in hybrid-reference files) The byte offset from the beginning of the file to the beginning of the previous cross-reference stream. This entry has the same function as the Prev entry in the trailer dictionary.

(Required) An array of integers representing the size of the fields in a single cross-reference entry. The table describes the types of entries and their fields. For PDF 1.5, W always contains three integers; the value of each integer is the number of bytes (in the decoded stream) of the corresponding field. For example, [1 2 1] means that the fields are one byte, two bytes, and one byte, respectively. A value of zero for an element in the W array indicates that the corresponding field is not present in the stream, and the default value is used, if there is one. If the first element is zero, the type field is not present, and it defaults to type 1. The sum of the items is the total length of each entry; it can be used with the Indexarray to determine the starting position of each subsection. Note: Different cross-reference streams in a PDF file may use different values for W. Entries in a cross-reference stream. TYPE FIELD DESCRIPTION 0 1 The type of this entry, which must be 0. Type 0 entries define the linked list of free objects (corresponding to f entries in a cross-reference table). 2 The object number of the next free object. 3 The generation number to use if this object number is used again. 1 1 The type of this entry, which must be 1. Type 1 entries define objects that are in use but are not compressed (corresponding to n entries in a cross-reference table). 2 The byte offset of the object, starting from the beginning of the file. 3 The generation number of the object. Default value: 0. 2 1 The type of this entry, which must be 2. Type 2 entries define compressed objects. 2 The object number of the object stream in which this object is stored. (The generation number of the object stream is implicitly 0.) 3 The index of this object within the object stream.

Note: For the standard 14 fonts, the entries FirstChar, LastChar, Widths, and FontDescriptor must either all be present or all be absent. Ordinarily, they are absent; specifying them enables a standard font to be overridden.

The PDF font descriptor flags.

All glyphs have the same width (as opposed to proportional or variable-pitch fonts, which have different widths).

Glyphs have serifs, which are short strokes drawn at an angle on the top and bottom of glyph stems. (Sans serif fonts do not have serifs.)

Glyphs resemble cursive handwriting.

Font uses the Adobe standard Latin character set or a subset of it.

Glyphs have dominant vertical strokes that are slanted.

Font contains no lowercase letters; typically used for display purposes, such as for titles or headlines.

Font contains both uppercase and lowercase letters. The uppercase letters are similar to those in the regular version of the same typeface family. The glyphs for the lowercase letters have the same shapes as the corresponding uppercase letters, but they are sized and their proportions adjusted so that they have the same size and stroke weight as lowercase glyphs in the same typeface family.

It must be one of the following names (ordered from narrowest to widest): UltraCondensed, ExtraCondensed, Condensed, SemiCondensed, Normal, SemiExpanded, Expanded, ExtraExpanded or UltraExpanded. Note: The specific interpretation of these values varies from font to font. For example, Condensed in one font may appear most similar to Normal in another.

(Optional; PDF 1.5; strongly recommended for Type 3 fonts in Tagged PDF documents) The weight (thickness) component of the fully-qualified font name or font specifier. The possible values are 100, 200, 300, 400, 500, 600, 700, 800, or 900, where each number indicates a weight that is at least as dark as its predecessor. A value of 400 indicates a normal weight; 700 indicates bold. Note: The specific interpretation of these values varies from font to font. For example, 300 in one font may appear most similar to 500 in another.

(Required) The type of XObject that this dictionary describes; must be Image for an image XObject.

(Required) The width of the image, in samples.

(Required) The height of the image, in samples.

(Required for images, except those that use the JPXDecode filter; not allowed for image masks) The color space in which image samples are specified; it can be any type of color space except Pattern. If the image uses the JPXDecode filter, this entry is optional: • If ColorSpace is present, any color space specifications in the JPEG2000 data are ignored. • If ColorSpace is absent, the color space specifications in the JPEG2000 data are used. The Decode array is also ignored unless ImageMask is true.

(Required except for image masks and images that use the JPXDecode filter) The number of bits used to represent each color component. Only a single value may be specified; the number of bits is the same for all color components. Valid values are 1, 2, 4, 8, and (in PDF 1.5) 16. If ImageMask is true, this entry is optional, and if specified, its value must be 1. If the image stream uses a filter, the value of BitsPerComponent must be consistent with the size of the data samples that the filter delivers. In particular, a CCITTFaxDecode or JBIG2Decode filter always delivers 1-bit samples, a RunLengthDecode or DCTDecode filter delivers 8-bit samples, and an LZWDecode or FlateDecode filter delivers samples of a specified size if a predictor function is used. If the image stream uses the JPXDecode filter, this entry is optional and ignored if present. The bit depth is determined in the process of decoding the JPEG2000 image.

(Optional; PDF 1.1) The name of a color rendering intent to be used in rendering the image. Default value: the current rendering intent in the graphics state.

(Optional) A flag indicating whether the image is to be treated as an image mask. If this flag is true, the value of BitsPerComponent must be 1 and Mask and ColorSpace should not be specified; unmasked areas are painted using the current non-stroking color. Default value: false.

(Optional except for image masks; not allowed for image masks; PDF 1.3) An image XObject defining an image mask to be applied to this image, or an array specifying a range of colors to be applied to it as a color key mask. If ImageMask is true, this entry must not be present.

(Optional) An array of numbers describing how to map image samples into the range of values appropriate for the image’s color space. If ImageMask is true, the array must be either [0 1] or [1 0]; otherwise, its length must be twice the number of color components required by ColorSpace. If the image uses the JPXDecode filter and ImageMask is false, Decode is ignored. Default value: see “Decode Arrays”.

(Optional) A flag indicating whether image interpolation is to be performed. Default value: false.

(Optional; PDF 1.3) An array of alternate image dictionaries for this image. The order of elements within the array has no significance. This entry may not be present in an image XObject that is itself an alternate image.

(Optional; PDF 1.4) A subsidiary image XObject defining a soft-mask image to be used as a source of mask shape or mask opacity values in the transparent imaging model. The alpha source parameter in the graphics state determines whether the mask values are interpreted as shape or opacity. If present, this entry overrides the current soft mask in the graphics state, as well as the image’s Mask entry, if any. (However, the other transparency related graphics state parameters — blend mode and alpha constant — remain in effect.) If SMask is absent, the image has no associated soft mask (although the current soft mask in the graphics state may still apply).

(Optional for images that use the JPXDecode filter, meaningless otherwise; PDF 1.5) A code specifying how soft-mask information encoded with image samples should be used: 0 If present, encoded soft-mask image information should be ignored. 1 The image’s data stream includes encoded soft-mask values. An application can create a soft-mask image from the information to be used as a source of mask shape or mask opacity in the transparency imaging model. 2 The image’s data stream includes color channels that have been preblended with a background; the image data also includes an opacity channel. An application can create a soft-mask image with a Matte entry from the opacity channel information to be used as a source of mask shape or mask opacity in the transparency model. If this entry has a nonzero value, SMask should not be specified. Default value: 0.

(Required in PDF 1.0; optional otherwise) The name by which this image XObject is referenced in the XObject subdictionary of the current resource dictionary.

(Required if the image is a structural content item; PDF 1.3) The integer key of the image’s entry in the structural parent tree.

(Optional; PDF 1.3; indirect reference preferred) The digital identifier of the image’s parent Web Capture content set.

(Optional; PDF 1.2) An OPI version dictionary for the image. If ImageMask is true, this entry is ignored.

(Optional; PDF 1.4) A metadata stream containing metadata for the image.

(Optional; PDF 1.5) An optional content group or optional content membership dictionary, specifying the optional content properties for this image XObject. Before the image is processed, its visibility is determined based on this entry. If it is determined to be invisible, the entire image is skipped, as if there were no Do operator to invoke it.

Represents a shading dictionary.

Initializes a new instance of the class.

Common keys for all streams.

(Required) The shading type: 1 Function-based shading 2 Axial shading 3 Radial shading 4 Free-form Gouraud-shaded triangle mesh 5 Lattice-form Gouraud-shaded triangle mesh 6 Coons patch mesh 7 Tensor-product patch mesh

(Required) The color space in which color values are expressed. This may be any device, CIE-based, or special color space except a Pattern space.

(Optional) An array of color components appropriate to the color space, specifying a single background color value. If present, this color is used, before any painting operation involving the shading, to fill those portions of the area to be painted that lie outside the bounds of the shading object. In the opaque imaging model, the effect is as if the painting operation were performed twice: first with the background color and then with the shading.

(Optional) An array of four numbers giving the left, bottom, right, and top coordinates, respectively, of the shading’s bounding box. The coordinates are interpreted in the shading’s target coordinate space. If present, this bounding box is applied as a temporary clipping boundary when the shading is painted, in addition to the current clipping path and any other clipping boundaries in effect at that time.

(Optional) A flag indicating whether to filter the shading function to prevent aliasing artifacts. The shading operators sample shading functions at a rate determined by the resolution of the output device. Aliasing can occur if the function is not smooth—that is, if it has a high spatial frequency relative to the sampling rate. Anti-aliasing can be computationally expensive and is usually unnecessary, since most shading functions are smooth enough or are sampled at a high enough frequency to avoid aliasing effects. Anti-aliasing may not be implemented on some output devices, in which case this flag is ignored. Default value: false.

(Required) An array of four numbers [x0 y0 x1 y1] specifying the starting and ending coordinates of the axis, expressed in the shading’s target coordinate space.

(Optional) An array of two numbers [t0 t1] specifying the limiting values of a parametric variable t. The variable is considered to vary linearly between these two values as the color gradient varies between the starting and ending points of the axis. The variable t becomes the input argument to the color function(s). Default value: [0.0 1.0].

(Required) A 1-in, n-out function or an array of n 1-in, 1-out functions (where n is the number of color components in the shading dictionary’s color space). The function(s) are called with values of the parametric variable t in the domain defined by the Domain entry. Each function’s domain must be a superset of that of the shading dictionary. If the value returned by the function for a given color component is out of range, it is adjusted to the nearest valid value.

(Optional) An array of two boolean values specifying whether to extend the shading beyond the starting and ending points of the axis, respectively. Default value: [false false].

Common keys for all streams.

(Optional) The type of PDF object that this dictionary describes; if present, must be Pattern for a pattern dictionary.

(Required) A code identifying the type of pattern that this dictionary describes; must be 2 for a shading pattern.

(Required) A shading object (see below) defining the shading pattern’s gradient fill.

(Optional) An array of six numbers specifying the pattern matrix. Default value: the identity matrix [1 0 0 1 0 0].

(Optional) A graphics state parameter dictionary containing graphics state parameters to be put into effect temporarily while the shading pattern is painted. Any parameters that are not so specified are inherited from the graphics state that was in effect at the beginning of the content stream in which the pattern is defined as a resource.

Gets the KeysMeta for these keys.

Gets the KeysMeta of this dictionary type.

Represents a PDF soft mask.

Initializes a new instance of the class.

The document that owns the object.

Predefined keys of this dictionary.

(Optional) The type of PDF object that this dictionary describes; if present, must be Mask for a soft-mask dictionary.

(Required) A subtype specifying the method to be used in deriving the mask values from the transparency group specified by the G entry: Alpha: Use the group’s computed alpha, disregarding its color. Luminosity: Convert the group’s computed color to a single-component luminosity value.

(Required) A transparency group XObject to be used as the source of alpha or color values for deriving the mask. If the subtype S is Luminosity, the group attributes dictionary must contain a CS entry defining the color space in which the compositing computation is to be performed.

(Optional) An array of component values specifying the color to be used as the backdrop against which to composite the transparency group XObject G. This entry is consulted only if the subtype S is Luminosity. The array consists of n numbers, where n is the number of components in the color space specified by the CS entry in the group attributes dictionary. Default value: the color space’s initial value, representing black.

(Optional) A function object specifying the transfer function to be used in deriving the mask values. The function accepts one input, the computed group alpha or luminosity (depending on the value of the subtype S), and returns one output, the resulting mask value. Both the input and output must be in the range 0.0 to 1.0; if the computed output falls outside this range, it is forced to the nearest valid value. The name Identity may be specified in place of a function object to designate the identity function. Default value: Identity.

Represents a tiling pattern dictionary.

Initializes a new instance of the class.

Common keys for all streams.

(Optional) The type of PDF object that this dictionary describes; if present, must be Pattern for a pattern dictionary.

(Required) A code identifying the type of pattern that this dictionary describes; must be 1 for a tiling pattern.

(Required) A code that determines how the color of the pattern cell is to be specified: 1: Colored tiling pattern. The pattern’s content stream specifies the colors used to paint the pattern cell. When the content stream begins execution, the current color is the one that was initially in effect in the pattern’s parent content stream. 2: Uncolored tiling pattern. The pattern’s content stream does not specify any color information. Instead, the entire pattern cell is painted with a separately specified color each time the pattern is used. Essentially, the content stream describes a stencil through which the current color is to be poured. The content stream must not invoke operators that specify colors or other color-related parameters in the graphics state; otherwise, an error occurs. The content stream may paint an image mask, however, since it does not specify any color information.

(Required) A code that controls adjustments to the spacing of tiles relative to the device pixel grid: 1: Constant spacing. Pattern cells are spaced consistently—that is, by a multiple of a device pixel. To achieve this, the application may need to distort the pattern cell slightly by making small adjustments to XStep, YStep, and the transformation matrix. The amount of distortion does not exceed 1 device pixel. 2: No distortion. The pattern cell is not distorted, but the spacing between pattern cells may vary by as much as 1 device pixel, both horizontally and vertically, when the pattern is painted. This achieves the spacing requested by XStep and YStep on average but not necessarily for each individual pattern cell. 3: Constant spacing and faster tiling. Pattern cells are spaced consistently as in tiling type 1 but with additional distortion permitted to enable a more efficient implementation.

(Required) An array of four numbers in the pattern coordinate system giving the coordinates of the left, bottom, right, and top edges, respectively, of the pattern cell’s bounding box. These boundaries are used to clip the pattern cell.

(Required) The desired horizontal spacing between pattern cells, measured in the pattern coordinate system.

(Required) The desired vertical spacing between pattern cells, measured in the pattern coordinate system. Note that XStep and YStep may differ from the dimensions of the pattern cell implied by the BBox entry. This allows tiling with irregularly shaped figures. XStep and YStep may be either positive or negative but not zero.

(Required) A resource dictionary containing all of the named resources required by the pattern’s content stream (see Section 3.7.2, “Resource Dictionaries”).

(Optional) An array of six numbers specifying the pattern matrix. Default value: the identity matrix [1 0 0 1 0 0].

Equivalently, this value is 1 greater than the highest object number used in the file. Note: Any object in a cross-reference section whose number is greater than this value is ignored and considered missing.

(Present only if the file has more than one cross-reference section; must not be an indirect reference) The byte offset from the beginning of the file to the beginning of the previous cross-reference section.

(Required; must be an indirect reference) The catalog dictionary for the PDF document contained in the file.

(Optional) The byte offset from the beginning of the file of a cross-reference stream.

Gets the KeysMeta for these keys.

Gets the KeysMeta of this dictionary type.

Represents a PDF transparency group XObject.

Predefined keys of this dictionary.

(Sometimes required, as discussed below) The group color space, which is used for the following purposes: • As the color space into which colors are converted when painted into the group • As the blending color space in which objects are composited within the group • As the color space of the group as a whole when it in turn is painted as an object onto its backdrop The group color space may be any device or CIE-based color space that treats its components as independent additive or subtractive values in the range 0.0 to 1.0, subject to the restrictions described in Section 7.2.3, “Blending Color Space.” These restrictions exclude Lab and lightness-chromaticity ICCBased color spaces, as well as the special color spaces Pattern, Indexed, Separation, and DeviceN. Device color spaces are subject to remapping according to the DefaultGray, DefaultRGB, and DefaultCMYK entries in the ColorSpace subdictionary of the current resource dictionary. Ordinarily, the CS entry is allowed only for isolated transparency groups (those for which I, below, is true), and even then it is optional. However, this entry is required in the group attributes dictionary for any transparency group XObject that has no parent group or page from which to inherit — in particular, one that is the value of the G entry in a soft-mask dictionary of subtype Luminosity. In addition, it is always permissible to specify CS in the group attributes dictionary associated with a page object, even if I is false or absent. In the normal case in which the page is imposed directly on the output medium, the page group is effectively isolated regardless of the I value, and the specified CS value is therefore honored. But if the page is in turn used as an element of some other page and if the group is non-isolated, CS is ignored and the color space is inherited from the actual backdrop with which the page is composited. Default value: the color space of the parent group or page into which this transparency group is painted. (The parent’s color space in turn can be either explicitly specified or inherited.)

(Optional) A flag specifying whether the transparency group is isolated. If this flag is true, objects within the group are composited against a fully transparent initial backdrop; if false, they are composited against the group’s backdrop. Default value: false. In the group attributes dictionary for a page, the interpretation of this entry is slightly altered. In the normal case in which the page is imposed directly on the output medium, the page group is effectively isolated and the specified I value is ignored. But if the page is in turn used as an element of some other page, it is treated as if it were a transparency group XObject; the I value is interpreted in the normal way to determine whether the page group is isolated.

(Optional) A flag specifying whether the transparency group is a knockout group. If this flag is false, later objects within the group are composited with earlier ones with which they overlap; if true, they are composited with the group’s initial backdrop and overwrite (“knock out”) any earlier overlapping objects. Default value: false.

(Required) The type of font; must be TrueType for a TrueType font.

(Required in PDF 1.0; optional otherwise) The name by which this font is referenced in the Font subdictionary of the current resource dictionary.

(Required) The PostScript name of the font. For Type 1 fonts, this is usually the value of the FontName entry in the font program; for more information. The Post-Script name of the font can be used to find the font’s definition in the consumer application or its environment. It is also the name that is used when printing to a PostScript output device.

(Required except for the standard 14 fonts) The first character code defined in the font’s Widths array.

(Required except for the standard 14 fonts) The last character code defined in the font’s Widths array.

(Required except for the standard 14 fonts; indirect reference preferred) An array of (LastChar - FirstChar + 1) widths, each element being the glyph width for the character code that equals FirstChar plus the array index. For character codes outside the range FirstChar to LastChar, the value of MissingWidth from the FontDescriptor entry for this font is used. The glyph widths are measured in units in which 1000 units corresponds to 1 unit in text space. These widths must be consistent with the actual widths given in the font program.

(Optional) A specification of the font’s character encoding if different from its built-in encoding. The value of Encoding is either the name of a predefined encoding (MacRomanEncoding, MacExpertEncoding, or WinAnsiEncoding, as described in Appendix D) or an encoding dictionary that specifies differences from the font’s built-in encoding or from a specified predefined encoding.

(Optional; PDF 1.2) A stream containing a CMap file that maps character codes to Unicode values.

Predefined keys of this dictionary.

(Required) The type of PDF object that this dictionary describes; must be Font for a font dictionary.

(Required) The type of font; must be Type0 for a Type 0 font.

(Required) The PostScript name of the font. In principle, this is an arbitrary name, since there is no font program associated directly with a Type 0 font dictionary. The conventions described here ensure maximum compatibility with existing Acrobat products. If the descendant is a Type 0 CIDFont, this name should be the concatenation of the CIDFont’s BaseFont name, a hyphen, and the CMap name given in the Encoding entry (or the CMapName entry in the CMap). If the descendant is a Type 2 CIDFont, this name should be the same as the CIDFont’s BaseFont name.

(Required) The name of a predefined CMap, or a stream containing a CMap that maps character codes to font numbers and CIDs. If the descendant is a Type 2 CIDFont whose associated TrueType font program is not embedded in the PDF file, the Encoding entry must be a predefined CMap name.

(Required) A one-element array specifying the CIDFont dictionary that is the descendant of this Type 0 font.

((Optional) A stream containing a CMap file that maps character codes to Unicode values.

Specifies the annotation flags.

If set, do not display the annotation if it does not belong to one of the standard annotation types and no annotation handler is available. If clear, display such an unknown annotation using an appearance stream specified by its appearancedictionary, if any.

(PDF 1.2) If set, do not display or print the annotation or allow it to interact with the user, regardless of its annotation type or whether an annotation handler is available. In cases where screen space is limited, the ability to hide and show annotations selectively can be used in combination with appearance streams to display auxiliary pop-up information similar in function to online help systems.

(PDF 1.2) If set, print the annotation when the page is printed. If clear, never print the annotation, regardless of whether it is displayed on the screen. This can be useful, for example, for annotations representing interactive pushbuttons, which would serve no meaningful purpose on the printed page.

(PDF 1.3) If set, do not scale the annotation’s appearance to match the magnification of the page. The location of the annotation on the page (defined by the upper-left corner of its annotation rectangle) remains fixed, regardless of the page magnification. See below for further discussion.

(PDF 1.3) If set, do not rotate the annotation’s appearance to match the rotation of the page. The upper-left corner of the annotation rectangle remains in a fixed location on the page, regardless of the page rotation. See below for further discussion.

(PDF 1.3) If set, do not display the annotation on the screen or allow it to interact with the user. The annotation may be printed (depending on the setting of the Print flag) but should be considered hidden for purposes of on-screen display and user interaction.

(PDF 1.3) If set, do not allow the annotation to interact with the user. The annotation may be displayed or printed (depending on the settings of the NoView and Print flags) but should not respond to mouse clicks or change its appearance in response to mouse motions. Note: This flag is ignored for widget annotations; its function is subsumed by the ReadOnly flag of the associated form field.

(PDF 1.4) If set, do not allow the annotation to be deleted or its properties (including position and size) to be modified by the user. However, this flag does not restrict changes to the annotation’s contents, such as the value of a form field.

(PDF 1.5) If set, invert the interpretation of the NoView flag for certain events. A typical use is to have an annotation that appears only when a mouse cursor is held over it.

Specifies the predefined icon names of rubber stamp annotations.

Gets or sets the text to be displayed for the annotation or, if this type of annotation does not display text, an alternate description of the annotation’s contents in human-readable form.

Gets or sets the color representing the components of the annotation. If the color has an alpha value other than 1, it is ignored. Use property Opacity to get or set the opacity of an annotation.

Gets or sets the constant opacity value to be used in painting the annotation. This value applies to all visible elements of the annotation in its closed state (including its background and border) but not to the popup window that appears when the annotation is opened.

Predefined keys of this dictionary.

(Optional) The type of PDF object that this dictionary describes; if present, must be Annot for an annotation dictionary.

(Required) The type of annotation that this dictionary describes.

(Required) The annotation rectangle, defining the location of the annotation on the page in default user space units.

(Optional) Text to be displayed for the annotation or, if this type of annotation does not display text, an alternate description of the annotation’s contents in human-readable form. In either case, this text is useful when extracting the document’s contents in support of accessibility to users with disabilities or for other purposes.

(Optional; PDF 1.4) The annotation name, a text string uniquely identifying it among all the annotations on its page.

(Optional; PDF 1.1) The date and time when the annotation was most recently modified. The preferred format is a date string, but viewer applications should be prepared to accept and display a string in any format.

(Optional; PDF 1.1) A set of flags specifying various characteristics of the annotation. Default value: 0.

(Optional; PDF 1.2) A border style dictionary specifying the characteristics of the annotation’s border.

(Optional; PDF 1.2) An appearance dictionary specifying how the annotation is presented visually on the page. Individual annotation handlers may ignore this entry and provide their own appearances.

(Required if the appearance dictionary AP contains one or more subdictionaries; PDF 1.2) The annotation’s appearance state, which selects the applicable appearance stream from an appearance subdictionary.

(Optional) An array specifying the characteristics of the annotation’s border. The border is specified as a rounded rectangle. In PDF 1.0, the array consists of three numbers defining the horizontal corner radius, vertical corner radius, and border width, all in default user space units. If the corner radii are 0, the border has square (not rounded) corners; if the border width is 0, no border is drawn. In PDF 1.1, the array may have a fourth element, an optional dash array defining a pattern of dashes and gaps to be used in drawing the border. The dash array is specified in the same format as in the line dash pattern parameter of the graphics state. For example, a Border value of [0 0 1 [3 2]] specifies a border 1 unit wide, with square corners, drawn with 3-unit dashes alternating with 2-unit gaps. Note that no dash phase is specified; the phase is assumed to be 0. Note: In PDF 1.2 or later, this entry may be ignored in favor of the BS entry.

(Optional; PDF 1.1) An array of three numbers in the range 0.0 to 1.0, representing the components of a color in the DeviceRGB color space. This color is used for the following purposes: • The background of the annotation’s icon when closed • The title bar of the annotation’s pop-up window • The border of a link annotation

(Required if the annotation is a structural content item; PDF 1.3) The integer key of the annotation’s entry in the structural parent tree.

(Optional; PDF 1.1) An action to be performed when the annotation is activated. Note: This entry is not permitted in link annotations if a Dest entry is present. Also note that the A entry in movie annotations has a different meaning.

(Optional; PDF 1.1) The text label to be displayed in the title bar of the annotation’s pop-up window when open and active. By convention, this entry identifies the user who added the annotation.

(Optional; PDF 1.3) An indirect reference to a pop-up annotation for entering or editing the text associated with this annotation.

(Optional; PDF 1.4) The constant opacity value to be used in painting the annotation. This value applies to all visible elements of the annotation in its closed state (including its background and border) but not to the popup window that appears when the annotation is opened. The specified value is not used if the annotation has an appearance stream; in that case, the appearance stream must specify any transparency. (However, if the viewer regenerates the annotation’s appearance stream, it may incorporate the CA value into the stream’s content.) The implicit blend mode is Normal. Default value: 1.0.

(Optional; PDF 1.5) Text representing a short description of the subject being addressed by the annotation.

Determines how a PDF document is opened.

The PDF stream is completely read into memory and can be modified. Pages can be deleted or inserted, but it is not possible to extract pages. This mode is useful for modifying an existing PDF document.

The PDF stream is opened for importing pages from it. A document opened in this mode cannot be modified.

The PDF stream is completely read into memory, but cannot be modified. This mode preserves the original internal structure of the document and is useful for analyzing existing PDF files.

The PDF stream is partially read for information purposes only. The only valid operation is to call the Info property at the imported document. This option is very fast and needs less memory and is e.g. useful for browsing information about a collection of PDF documents in a user interface.

Determines how the PDF output stream is formatted. Even all formats create valid PDF files, only Compact or Standard should be used for production purposes.

The PDF stream contains no unnecessary characters. This is default in release build.

The PDF stream contains some superfluous line feeds but is more readable.

The PDF stream is indented to reflect the nesting levels of the objects. This is useful for analyzing PDF files, but increases the size of the file significantly.

The PDF stream is indented to reflect the nesting levels of the objects and contains additional information about the PDFsharp objects. Furthermore, content streams are not deflated. This is useful for debugging purposes only and increases the size of the file significantly.

PDF Terminal symbols recognized by lexer.

Lexical analyzer for PDF files. Technically a PDF file is a stream of bytes. Some chunks of bytes represent strings in several encodings. The actual encoding depends on the context where the string is used. Therefore, the bytes are 'raw encoded' into characters, i.e. a character or token read by the Lexer has always character values in the range from 0 to 255.

Initializes a new instance of the Lexer class.

Gets or sets the logical current position within the PDF stream.
When got, the logical position of the stream pointer is returned. The actual position in the .NET Stream is two bytes more, because the reader has a look-ahead of two bytes (_currChar and _nextChar).
When set, the logical position is set and 2 bytes of look-ahead are red into _currChar and _nextChar.
This ensures that immediately getting and setting or setting and getting is idempotent.

Reads the next token and returns its type. If the token starts with a digit, the parameter testForObjectReference specifies how to treat it. If it is false, the Lexer scans for a single integer. If it is true, the Lexer checks if the digit is the prefix of a reference. If it is a reference, the token is set to the object ID followed by the generation number separated by a blank (the 'R' is omitted from the token).

Reads a string in 'raw' encoding without changing the state of the lexer.

Scans a comment line.

Scans a name.

Scans a number or an object reference. Returns one of the following symbols. Symbol.ObjRef if testForObjectReference is true and the pattern "nnn ggg R" can be found. Symbol.Real if a decimal point exists or the number of digits is too large for 64-bit integer. Symbol.Integer if the long value is in the range of 32-bit integer. Symbol.LongInteger otherwise.

Scans a keyword.

Scans a string literal, contained between "(" and ")".

Scans a hex encoded literal string, contained between "<" and ">".

Tries to scan the specified literal from the current stream position.

Return the exact position where the content of the stream starts. The logical position is also set to this value when the function returns.

Tries to scan 'endstream' after reading the stream content with a logical position on the first byte behind the read stream content. Returns true if success. The logical position is then immediately behind 'endstream'. In case of false the logical position is not well-defined.

Reads a string in 'raw' encoding.

Move current position one byte further in PDF stream and return it as a character with high byte always zero.

Resets the current token to the empty string.

Appends current character to the token and reads next byte as a character.

Returns the neighborhood of the specified position as a string. It supports a human to find this position in a PDF file. The current position is tagged with a double quotation mark ('‼').

Internal function to read PDF object from input stream.

Either the instance of a derived type or null. If it is null an appropriate object is created. The address of the object. If true, specifies that all indirect objects are included recursively. If true, the object is parsed from an object stream. Suppresses exceptions that may be caused by not yet available objects.

Reads the content of a stream between 'stream' and 'endstream'. Because Acrobat is very tolerant with the crap some producer apps crank out, it is more work than expected in the first place.
Reference: 3.2.7 Stream Objects / Page 60 Reference 2.0: 7.3.8 Stream objects / Page 31

Suppresses exceptions that may be caused by not yet available objects.

Read stream length from /Length entry of the dictionary. But beware, /Length may be an indirect object. Furthermore, it can be an indirect object located in an object stream that was not yet parsed. And though /Length is a required entry in a stream dictionary, some PDF file miss it anyway in some dictionaries. In this case, we look for '\nendstream' backwards form the beginning of the object immediately behind this object or, in case this object itself is the last one in the PDF file, we start searching from the end of the whole file.

Try to read 'endstream' after reading the stream content. Sometimes the Length is not exact and ReadSymbol fails. In this case we search the token 'endstream' in the neighborhood where Length points.

(Optional) The method used, if any, by the PDF reader to decrypt data. The following values shall be supported: None The application shall not decrypt data but shall direct the input stream to the security handler for decryption. V2 (Deprecated in PDF 2.0) The application shall ask the security handler for the file encryption key and shall implicitly decrypt data with 7.6.3.2, "Algorithm 1: Encryption of data using the RC4 or AES algorithms", using the RC4 algorithm. AESV2 (PDF 1.6; deprecated in PDF 2.0) The application shall ask the security handler for the file encryption key and shall implicitly decrypt data with 7.6.3.2, "Algorithm 1: Encryption of data using the RC4 or AES algorithms", using the AES algorithm in Cipher Block Chaining (CBC) mode with a 16-byte block size and an initialization vector that shall be randomly generated and placed as the first 16 bytes in the stream or string. The key size (Length) shall be 128 bits. AESV3 (PDF 2.0) The application shall ask the security handler for the file encryption key and shall implicitly decrypt data with 7.6.3.3, "Algorithm 1.A: Encryption of data using the AES algorithms", using the AES-256 algorithm in Cipher Block Chaining (CBC) with padding mode with a 16-byte block size and an initialization vector that is randomly generated and placed as the first 16 bytes in the stream or string. The key size (Length) shall be 256 bits. When the value is V2, AESV2 or AESV3, the application may ask once for this file encryption key and cache the key for subsequent use for streams that use the same crypt filter. Therefore, there shall be a one-to-one relationship between a crypt filter name and the corresponding file encryption key. Only the values listed here shall be supported. Applications that encounter other values shall report that the file is encrypted with an unsupported algorithm. Default value: None.

(Optional) The event that shall be used to trigger the authorization that is required to access file encryption keys used by this filter. If authorization fails, the event shall fail. Valid values shall be: DocOpen Authorization shall be required when a document is opened. EFOpen Authorization shall be required when accessing embedded files. Default value: DocOpen. If this filter is used as the value of StrF or StmF in the encryption dictionary, the PDF reader shall ignore this key and behave as if the value is DocOpen.

(Required; deprecated in PDF 2.0) Security handlers may define their own use of the Length entry and should use it to define the bit length of the file encryption key. The bit length of the file encryption key shall be a multiple of 8 in the range of 40 to 256. The standard security handler expresses the Length entry in bytes (e.g., 32 means a length of 256 bits) and public-key security handlers express it as is (e.g., 256 means a length of 256 bits). When CFM is AESV2, the Length key shall have the value of 128. When CFM is AESV3, the Length key shall have a value of 256.
