import "github.com/benoitkugler/textlayout/fonts/type1C"

Package type1c provides a parser for the CFF font format defined at https://www.adobe.com/content/dam/acom/en/devnet/font/pdfs/5176.CFF.pdf. It can be used to read standalone CFF font files, but is mainly used through the truetype package to read embedded CFF glyph tables.

Types ¶

type Font ¶

type Font struct {
	Encoding *simpleencodings.Encoding

	fonts.PSInfo
	// contains filtered or unexported fields
}

Font represents a parsed Font font.

func Load ¶

func Load(file fonts.Resource) ([]Font, error)

Load reads standalone .cff font files and may return multiple fonts.

func Parse ¶

func Parse(file fonts.Resource) (*Font, error)

Parse parse a .cff font file. Although CFF enables multiple font or CIDFont programs to be bundled together in a single file, embedded CFF font file in PDF or in TrueType/OpenType fonts shall consist of exactly one font or CIDFont. Thus, this function returns an error if the file contains more than one font. See Loader to read standalone .cff files

func (*Font) Cmap ¶

func (f *Font) Cmap() (fonts.Cmap, fonts.CmapEncoding)

func (*Font) GlyphName ¶

func (f *Font) GlyphName(glyph fonts.GID) string

GlyphName returns the name of the glyph or an empty string if not found.

func (*Font) LoadGlyph ¶

func (f *Font) LoadGlyph(glyph fonts.GID) ([]fonts.Segment, ps.PathBounds, error)

LoadGlyph parses the glyph charstring to compute segments and path bounds. It returns an error if the glyph is invalid or if decoding the charstring fails.

func (*Font) LoadSummary ¶

func (f *Font) LoadSummary() (fonts.FontSummary, error)

func (*Font) NumGlyphs ¶

func (f *Font) NumGlyphs() int

NumGlyphs returns the number of glyphs in this font. It is also the maximum glyph index + 1.

func (*Font) PoscriptName ¶

func (f *Font) PoscriptName() string

func (*Font) PostscriptInfo ¶

func (f *Font) PostscriptInfo() (fonts.PSInfo, bool)
