Member Data Documentation

uint32_t* BLGlyphBufferImpl::content

Text (UCS4 code-points) or glyph content.

BLGlyphPlacement* BLGlyphBufferImpl::placementData

Glyph placement data.

size_t BLGlyphBufferImpl::size

Number of either code points or glyph indexes in the glyph-buffer.

uint32_t BLGlyphBufferImpl::reserved

Reserved, used exclusively by BLGlyphRun.

uint32_t BLGlyphBufferImpl::flags

Flags shared between BLGlyphRun and BLGlyphBuffer.

BLGlyphRun BLGlyphBufferImpl::glyphRun

Glyph run data that can be passed directly to the rendering context.

Glyph run shares data with other members like content, placementData, size, and flags. When working with data it's better to access these members directly as they are typed, whereas BLGlyphRun stores pointers as const void* as it offers more flexibility, which BLGlyphRun doesn't need.

BLGlyphInfo* BLGlyphBufferImpl::infoData

Glyph info data - additional information of each code-point or glyph.
