Uniscribe Functions
This section describes functions for typography and for complex script processing.
| Function | Description |
|---|---|
| ScriptApplyDigitSubstitution | Applies the specified digit substitution settings to the specified script control and script state structures. |
| ScriptApplyLogicalWidth | Takes an array of advance widths for a run and generates an array of adjusted advance glyph widths. |
| ScriptBreak | Retrieves information for determining line breaks. |
| ScriptCacheGetHeight | Retrieves the height of the currently cached font. |
| ScriptCPtoX | Generates the x offset from the left end or leading edge of a run to either the leading or trailing edge of a logical character cluster. |
| ScriptFreeCache | Frees a script cache. |
| ScriptGetCMap | Retrieves the glyph indexes of the Unicode characters in a string according to either the TrueType cmap table or the standard cmap table implemented for old-style fonts. |
| ScriptGetFontAlternateGlyphs | Retrieves a list of alternate glyphs for a specified character that can be accessed through a specified OpenType feature. |
| ScriptGetFontFeatureTags | Retrieves a list of typographic features for the defined writing system for OpenType processing. |
| ScriptGetFontLanguageTags | Retrieves a list of language tags that are available for the specified item and are supported by a specified script tag for OpenType processing. |
| ScriptGetFontProperties | Retrieves information from the font cache on the special glyphs used by a font. |
| ScriptGetFontScriptTags | Retrieves a list of scripts available in the font for OpenType processing. |
| ScriptGetGlyphABCWidth | Retrieves the ABC width of a given glyph. |
| ScriptGetLogicalWidths | Converts the glyph advance widths for a specific font into logical widths. |
| ScriptGetProperties | Retrieves information about the current scripts. |
| ScriptIsComplex | Determines whether a Unicode string requires complex script processing. |
| ScriptItemize | Breaks a Unicode string into individually shapeable items. |
| ScriptItemizeOpenType | Breaks a Unicode string into individually shapeable items and provides an array of feature tags for each shapeable item for OpenType processing. |
| ScriptJustify | Creates an advance widths table to allow text justification when passed to the ScriptTextOut function. |
| ScriptLayout | Converts an array of run embedding levels to a map of visual-to-logical position and/or logical-to-visual position. |
| ScriptPlace | Generates glyph advance width and two-dimensional offset information from the output of ScriptShape. |
| ScriptPlaceOpenType | Generates glyphs and visual attributes for a Unicode run with OpenType information from the output of ScriptShapeOpenType. |
| ScriptPositionSingleGlyph | Positions a single glyph with a single adjustment using a specified feature provided in the font for OpenType processing. |
| ScriptRecordDigitSubstitution | Reads the National Language Support (NLS) native digit and digit substitution settings and records them in a SCRIPT_DIGITSUBSTITUTE structure. |
| ScriptShape | Generates glyphs and visual attributes for a Unicode run. |
| ScriptShapeOpenType | Generates glyphs and visual attributes for a Unicode run with OpenType information. |
| ScriptStringAnalyse | Analyzes a plain text string. |
| ScriptStringCPtoX | Retrieves the x coordinate for the leading or trailing edge of a character position. |
| ScriptStringFree | Frees a SCRIPT_STRING_ANALYSIS structure. |
| ScriptStringGetLogicalWidths | Converts visual widths into logical widths. |
| ScriptStringGetOrder | Creates an array that maps an original character position to a glyph position. |
| ScriptStringOut | Displays a string generated by a prior call to ScriptStringAnalyse and optionally adds highlighting. |
| ScriptString_pcOutChars | Returns a pointer to the length of a string after clipping. |
| ScriptString_pLogAttr | Returns a pointer to a logical attributes buffer for an analyzed string. |
| ScriptString_pSize | Returns a pointer to a SIZE structure for an analyzed string. |
| ScriptStringValidate | Checks a SCRIPT_STRING_ANALYSIS structure for invalid sequences. |
| ScriptStringXtoCP | Converts an x coordinate to a character position. |
| ScriptSubstituteSingleGlyph | Enables substitution of a single glyph with one alternate form of the same glyph for OpenType processing. |
| ScriptTextOut | Displays text for the specified script shape and place information. |
| ScriptXtoCP | Generates the leading or trailing edge of a logical character cluster from the x offset of a run. |
