type CIDFont 

type CIDFont struct {

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

	// (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;
	// see Section 5.5.2, “TrueType Fonts.” In either case, the name can have a sub-
	// set prefix if appropriate; see Section 5.5.3, “Font Subsets.”
	BaseFont Name

	// (Required) A dictionary containing entries that define the character collec-
	// tion of the CIDFont. See Table 5.12 on page 337.
	CIDSystemInfo Object

	// (Required; must be an indirect reference) A font descriptor describing the
	// CIDFont’s default metrics other than its glyph widths (see Section 5.7,
	// “Font Descriptors”).

	// (Optional) The default width for glyphs in the CIDFont (see “Glyph Met-
	// rics in CIDFonts” on page 340). Default value: 1000.
	DW Object

	// (Optional) A description of the widths for the glyphs in the CIDFont. The
	// array’s elements have a variable format that can specify individual widths
	// for consecutive CIDs or one width for a range of CIDs (see “Glyph Metrics
	// in CIDFonts” on page 340). Default value: none (the DW value is used for
	// all glyphs).
	W Object

	// (Optional; applies only to CIDFonts used for vertical writing) An array of two
	// numbers specifying the default metrics for vertical writing (see “Glyph
	// Metrics in CIDFonts” on page 340). Default value: [880 −1000].

	// used for all glyphs).
	W2 Object

	// (Optional; Type 2 CIDFonts only) A specification of the mapping from CIDs
	// to glyph indices. 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 (see the next section).

	// space except Pattern.
	ColorSpace Object

	// (Required except for image masks; optional for image masks) 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, and 8. 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 par-

	// an LZWDecode or FlateDecode filter delivers samples of a specified size if
	// a predictor function is used.
	BitsPerComponent Int

	// 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).
	SMask Object

	// (Optional) An array of numbers describing how to map image samples
	// into the range of values appropriate for the image’s color space (see

	// color components required by ColorSpace. Default value: see “Decode
	// Arrays” on page 271.
	Decode Array

	// (Optional) A flag indicating whether image interpolation is to be per-
	//formed (see “Image Interpolation” on page 273). Default value: false.
	Interpolate Boolean

	// XObject that is itself an alternate image.
	Alternates Array

	// (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 (see Section 3.7.2, “Resource Dictionaries”).

type StreamDictionary added in v1.0.5 

type StreamDictionary struct {
	// (Required) The number of bytes from the beginning of the line fol-
	// lowing the keyword stream to the last byte just before the keyword
	// endstream. (There may be an additional EOL marker, preceding
	// endstream, that is not included in the count and is not logically part
	// of the stream data.) See “Stream Extent,” above, for further discus-
	// sion.
	Length int

	// (Optional) The name of a filter to be applied in processing the stream
	// data found between the keywords stream and endstream, or an array
	// of such names. Multiple filters should be specified in the order in
	// which they are to be applied.
	Filter []Filter // name or array

	// (Optional) A parameter dictionary, or an array of such dictionaries,
	// used by the filters specified by Filter. If there is only one filter and that
	// filter has parameters, DecodeParms must be set to the filter’s parame-
	// ter dictionary unless all the filter’s parameters have their default
	// values, in which case the DecodeParms entry may be omitted. If there
	// are multiple filters and any of the filters has parameters set to non-
	// default values, DecodeParms must be an array with one entry for
	// each filter: either the parameter dictionary for that filter, or the null
	// object if that filter has no parameters (or if all of its parameters have
	// their default values). If none of the filters have parameters, or if all
	// their parameters have default values, the DecodeParms entry may be
	// omitted. (See implementation note 7 in Appendix H.)
	DecodeParms Object // dictionary or array

	// (Optional; PDF 1.2) The file containing the stream data. If this entry
	// is present, the bytes between stream and endstream are ignored, the
	// filters are specified by FFilter rather than Filter, and the filter parame-
	// ters are specified by FDecodeParms rather than DecodeParms. How-
	// ever, the Length entry should still specify the number of those bytes.
	// (Usually there are no bytes and Length is 0.)
	F Object // file specification

	// (Optional; PDF 1.2) The name of a filter to be applied in processing
	// the data found in the stream’s external file, or an array of such names.
	// The same rules apply as for Filter.
	FFilter []Filter // name or array

	// (Optional; PDF 1.2) A parameter dictionary, or an array of such dic-
	// tionaries, used by the filters specified by FFilter. The same rules apply
	// as for DecodeParms.

type Type0Font 

type Type0Font struct {

	// (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 program itself). If the
	// descendant is a Type 2 CIDFont, this name should be the same as the
	// CIDFont’s BaseFont name.
	BaseFont Name

	// (Required) The name of a predefined CMap, or a stream containing a CMap
	// stream program, that maps character codes to font numbers and CIDs. If the descen-
	// dant is a Type 2 CIDFont whose associated TrueType font program is not em-
	// bedded in the PDF file, the Encoding entry must be a predefined CMap name
	// (see “Glyph Selection in CIDFonts” on page 339).
	Encoding Object // name or dictionary

	// (Required) An array specifying one or more fonts or CIDFonts that are
	// descendants of this composite font. This array is indexed by the font number
	// that is obtained by mapping a character code through the CMap specified in
	// the Encoding entry.
	// Note: In all PDF versions up to and including PDF 1.4, DescendantFonts must
	// be a one-element array containing a CIDFont dictionary.
	DescendantFonts Array

	// (Optional) A stream containing a CMap file that maps character codes to

type Type3Font added in v1.0.5 

type Type3Font struct {

	//	(Required in PDF 1.0; optional otherwise) See Table 5.8 on page 317.
	Name Name

	//	(Required) A rectangle (see Section 3.8.3, “Rectangles”), expressed in the
	//	glyph coordinate system, specifying the font bounding box. This is the small-
	//	est rectangle enclosing the shape that would result if all of the glyphs of the
	//	font were placed with their origins coincident and then filled.
	//	If all four elements of the rectangle are zero, no assumptions are made based
	//	on the font bounding box. If any element is nonzero, it is essential that the
	//	font bounding box be accurate; if any glyph’s marks fall outside this bound-
	//	ing box, incorrect behavior may result.
	FontBBox Rectangle

	//	(Required) An array of six numbers specifying the font matrix, mapping
	//	glyph space to text space (see Section 5.1.3, “Glyph Positioning and
	//	Metrics”). A common practice is to define glyphs in terms of a 1000-unit
	//	glyph coordinate system, in which case the font matrix is
	// [0.001 0 0 0.001 0 0].
	FontMatrix Array

	//	(Required) A dictionary in which each key is a character name and the value
	//	associated with that key is a content stream that constructs and paints the
	//	glyph for that character. The stream must include as its first operator either
	//	d0 or d1. This is followed by operators describing one or more graphics
	//	objects, which may include path, text, or image objects. See below for more
	//	details about Type 3 glyph descriptions.
	CharProcs Object

	//	(Required) An encoding dictionary whose Differences array specifies the
	//	complete character encoding for this font (see Section 5.5.5, “Character
	//	Encoding”; also see implementation note 46 in Appendix H).
	Encoding Object

	//	(Required) The first character code defined in the font’s Widths array.
	FirstChar Int

	//	(Required) The last character code defined in the font’s Widths array.
	LastChar Int

	//	(Required; indirect reference preferred) An array of (LastChar − FirstChar + 1)
	//	widths, each element being the glyph width for the character whose code is
	//	FirstChar plus the array index. For character codes outside the range FirstChar
	//	to LastChar, the width is 0. These widths are interpreted in glyph space as
	//	specified by FontMatrix (unlike the widths of a Type 1 font, which are in
	//	thousandths of a unit of text space).
	//	Note: If FontMatrix specifies a rotation, only the horizontal component of the
	//	transformed width is used. That is, the resulting displacement is always horizon-
	//	tal in text space, as is the case for all simple fonts.
	Widths Object

	//	(Optional but strongly recommended; PDF 1.2) A list of the named resources,
	//	such as fonts and images, required by the glyph descriptions in this font (see
	//	Section 3.7.2, “Resource Dictionaries”). If any glyph descriptions refer to
	//	named resources but this dictionary is absent, the names are looked up in the
	//	resource dictionary of the page on which the font is used. (See implementa-
	//	tion note 47 in Appendix H.)
	Resources Object

	//	(Optional; PDF 1.2) A stream containing a CMap file that maps character
	//	codes to Unicode values (see Section 5.9, “ToUnicode CMaps”).
