Member Function Documentation

void kanzi::GlyphCacheManager::setGlyphCacheSize	(	unsigned int	glyphCacheWidth,
		unsigned int	glyphCacheHeight
	)

Sets the size of the textures in glyph caches created by the glyph cache manager.

Parameters

glyphCacheWidth	Width of textures.
glyphCacheHeight	Height of textures.

GlyphCacheSharedPtr kanzi::GlyphCacheManager::acquireGlyphCache	(	FontFileSharedPtr	font,
		float	fontSize
	)

Retrieves the glyph cache associated with the given font file and font size.

If a glyph cache does not yet exist, this function creates a glyph cache. Even if the there are no users for the glyph cache, the GlyphCacheManager keeps the glyph cache alive until purgeGlyphCaches() is called.

Parameters

font	Font used for rendering glyphs in the glyph cache.
fontSize	Size of the Font used for rendering glyphs in the glyph cache.

Returns

Pointer to the glyph cache.

void kanzi::GlyphCacheManager::purgeGlyphCaches

(

)
