Detailed Description

A grid representing a rendered glyph, with each grid pixel representing pixel coverage in the range (0,1).

This is used internally to create signed-distance field images for a font.

Member Data Documentation

bool ion::text::Font::GlyphGrid::is_sdf

When a Font is set up for rendering, the pixels are replaced with a signed-distance field (SDF).

This flag is set to true if the grid has SDF data (vs. the original rendered data).
