GetFontColorGlyphByIndex

Text, fonts, colour glyphs

Description

Returns the COLR, SVG-in-OpenType, sbix or CBDT/CBLC representation attached to a zero-based glyph index

Function TPDFlib.GetFontColorGlyphByIndex(FontID, GlyphIndex, PaletteIndex, PreferredPPEM: Integer; Out Glyph: TPDFlibColorGlyph): Integer;

FontID	A font handle returned by a font creation or loading API
GlyphIndex	The zero-based OpenType glyph index
PaletteIndex	The zero-based CPAL palette to resolve
PreferredPPEM	The desired bitmap strike size, or `0` for the largest strike
Glyph	Receives the colour representation and optional payload

Returns 1 when colour data exists or 0 when the handle, glyph index or colour tables are unsupported

This overload avoids a second cmap lookup when a shaping engine or previous inspection call already supplied the glyph index

The lightweight colour-table reader is retained under the shared font-cache byte budget and is reused by both colour-glyph entry points
