IDWriteTextAnalyzer interface (dwrite.h)
Analyzes various text properties for complex script processing such as bidirectional (bidi) support for languages like Arabic, determination of line break opportunities, glyph placement, and number substitution.
Inheritance
The IDWriteTextAnalyzer interface inherits from the IUnknown interface. IDWriteTextAnalyzer also has these types of members:
Methods
The IDWriteTextAnalyzer interface has these methods.
| IDWriteTextAnalyzer::AnalyzeBidi Analyzes a text range for script directionality, reading attributes from the source and reporting levels to the sink callback SetBidiLevel. |
| IDWriteTextAnalyzer::AnalyzeLineBreakpoints Analyzes a text range for potential breakpoint opportunities, reading attributes from the source and reporting breakpoint opportunities to the sink callback SetLineBreakpoints. |
| IDWriteTextAnalyzer::AnalyzeNumberSubstitution Analyzes a text range for spans where number substitution is applicable, reading attributes from the source and reporting substitutable ranges to the sink callback SetNumberSubstitution. |
| IDWriteTextAnalyzer::AnalyzeScript Analyzes a text range for script boundaries, reading text attributes from the source and reporting the Unicode script ID to the sink callback SetScript. |
| IDWriteTextAnalyzer::GetGdiCompatibleGlyphPlacements Place glyphs output from the GetGlyphs method according to the font and the writing system's rendering rules. |
| IDWriteTextAnalyzer::GetGlyphPlacements Places glyphs output from the GetGlyphs method according to the font and the writing system's rendering rules. |
| IDWriteTextAnalyzer::GetGlyphs Parses the input text string and maps it to the set of glyphs and associated glyph data according to the font and the writing system's rendering rules. |
