Uniscribe Functions

The following table shows the Uniscribe functions .

Programming element	Description
ScriptApplyDigitSubstitution	Applies the digit substitution settings recorded in a SCRIPT_DIGITSUBSTITUTE structure to the SCRIPT_CONTROL and SCRIPT_STATE structures.
ScriptApplyLogicalWidth	Takes an array of advance widths for a run and generates an array of glyph widths that are suitable for passing to the piJustify parameter of ScriptTextOut.
ScriptBreak	Returns information for determining line breaks.
ScriptCacheGetHeight	Returns the height of the currently cached font.
ScriptCPtoX	Generates the x offset from the left end (!fLogicalOrder) or leading edge (fLogicalOrder) of a run to either the leading or trailing edge of a logical character cluster.
ScriptFreeCache	Frees a SCRIPT_CACHE item.
ScriptGetCMap	Takes a string and returns the glyph indices of the Unicode characters according to the TrueType cmap table or the standard cmap table implemented for old style fonts.
ScriptGetFontProperties	Returns information from the font cache on the special glyphs used by a font.
ScriptGetGlyphABCWidth	Returns the ABC width of a given glyph.
ScriptGetLogicalWidths	Converts the glyph advance widths for a specific font into logical widths.
ScriptGetProperties	Returns information about the current scripts.
ScriptIsComplex	Determines whether a Unicode string requires complex script processing.
ScriptItemize	Breaks a Unicode string into individually shapeable items.
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	Takes the output of a ScriptShape call and generates glyph advance width and two-dimensional offset information.
ScriptRecordDigitSubstitution	Reads the National Language Support (NLS) native digit and digit substitution settings and records them in the SCRIPT_DIGITSUBSTITUTE structure.
ScriptShape	Takes a Unicode run and generates glyphs and visual attributes.
ScriptStringAnalyse	Analyzes a plain text string.
ScriptStringCPtoX	Returns 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	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 the SCRIPT_STRING_ANALYSIS structure for invalid sequences.
ScriptStringXtoCP	Converts an x-coordinate to a character position.
ScriptTextOut	Takes the output of both ScriptShape and ScriptPlace calls and calls the operating system ExtTextOut function appropriately.
ScriptXtoCP	Converts an x offset from the left end (!fLogicalOrder) or leading edge (fLogicalOrder) of a run to a logical character position and a flag that indicates whether the x position fell in the leading or the trailing half of the character.
