NAME¶

FLT_API - API provided by libm17n-flt.so.

Data Structures¶

struct MFLTGlyph Type of information about a glyph. struct MFLTGlyphAdjustment Type of information about a glyph position adjustment. struct MFLTGlyphString Type of information about a glyph sequence. struct MFLTOtfSpec Type of specification of GSUB and GPOS OpenType tables. struct MFLTFont Type of font to be used by the FLT driver.

Typedefs¶

typedef struct _MFLT MFLT Type of FLT (Font Layout Table).

Functions¶

MFLT * mflt_get (MSymbol name) Return an FLT object that has a specified name. MFLT * mflt_find (int c, MFLTFont *font) Find an FLT suitable for the specified character and font. const char * mflt_name (MFLT *flt) Return the name of an FLT. MCharTable * mflt_coverage (MFLT *flt) Return a coverage of a FLT. int mflt_run (MFLTGlyphString *gstring, int from, int to, MFLTFont *font, MFLT *flt) Layout characters with an FLT. MFLT * mdebug_dump_flt (MFLT *flt, int indent) Dump a Font Layout Table. void mflt_dump_gstring (MFLTGlyphString *gstring) Dump an MFLTGlyphString.

Variables¶

int mflt_enable_new_feature Flag to control several new OTF handling commands. int(* mflt_iterate_otf_feature )(struct _MFLTFont *font, MFLTOtfSpec *spec, int from, int to, unsigned char *table) MSymbol(* mflt_font_id )(struct _MFLTFont *font) int(* mflt_try_otf )(struct _MFLTFont *font, MFLTOtfSpec *spec, MFLTGlyphString *gstring, int from, int to)

Detailed Description¶

API provided by libm17n-flt.so. FLT support for a window system. This section defines the m17n FLT API concerning character layouting facility using FLT (Font Layout Table). The format of FLT is described in mdbFLT.

MFLTGlyphString¶

FIELD DOCUMENTATION: int MFLTGlyphString::glyph_size
(MFLTGlyph)'. MFLTGlyph* MFLTGlyphString::glyphs int MFLTGlyphString::allocated int MFLTGlyphString::used unsigned int MFLTGlyphString::r2l

MFLTOtfSpec¶

FIELD DOCUMENTATION: MSymbol MFLTOtfSpec::sym unsigned int MFLTOtfSpec::script unsigned int MFLTOtfSpec::langsys unsigned int* MFLTOtfSpec::features[2] (1) The case of using this information for selecting which features to apply to a glyph string. If the array is NULL, apply no feature. If the first element is 0xFFFFFFFF, apply all available features except for what appear in the second and following elements (if any). Otherwise, apply all listed features. (2) The case of using this information for checking if a a font can be drived by a specific FLT. If the array is NULL, the font should not have any features. Otherwize, the font should have all features before 0xFFFFFFFF element (if any) and should not have any features after that element.

MFLTFont¶

FIELD DOCUMENTATION: MSymbol MFLTFont::family int MFLTFont::x_ppem int MFLTFont::y_ppem int(* MFLTFont::get_glyph_id)(struct _MFLTFont *font, MFLTGlyphString *gstring, int from, int to) int(* MFLTFont::get_metrics)(struct _MFLTFont *font, MFLTGlyphString *gstring, int from, int to) int(* MFLTFont::check_otf)(struct _MFLTFont *font, MFLTOtfSpec *spec) int(* MFLTFont::drive_otf)(struct _MFLTFont *font, MFLTOtfSpec *spec, MFLTGlyphString *in, int from, int to, MFLTGlyphString *out, MFLTGlyphAdjustment *adjustment) void* MFLTFont::internal

Typedef Documentation¶

typedef struct _MFLT MFLT¶

Type of FLT (Font Layout Table). The type MFLT is for an FLT object. Its internal structure is concealed from application programs.

Variable Documentation¶

int mflt_enable_new_feature¶

Flag to control several new OTF handling commands. If the variable mflt_enable_new_feature is nonzero, the function mflt_run() can drive a Font Layout Table that contains the new OTF-related commands ':otf?' and/or OTF feature specification in a category table.

int(* mflt_iterate_otf_feature)(struct _MFLTFont *font, MFLTOtfSpec *spec, int from, int to, unsigned char *table)¶

MSymbol(* mflt_font_id)(struct _MFLTFont *font)¶

int(* mflt_try_otf)(struct _MFLTFont *font, MFLTOtfSpec *spec, MFLTGlyphString *gstring, int from, int to)¶
