GlyphAtlas() [1/3]

MayaFlux::Portal::Text::GlyphAtlas::GlyphAtlas ( FontFace &  face, uint32_t  pixel_size, uint32_t  atlas_size = 512  )

explicit

Construct an atlas for a specific face and pixel size.

Parameters

face	Loaded FontFace. Must outlive this atlas.
pixel_size	Glyph height in pixels (width is derived by FreeType).
atlas_size	Width and height of the atlas texture in pixels. Must be a power of two. Default 512 is sufficient for ASCII + extended Latin at sizes up to ~48px.
