not if you do subpixel aliasing
- kragen 3y agoyou mean subpixel antialiasing. but yes, as it turns out, type renderers do cache subpixel-antialiased pixmaps. the part where this gets tricky is with subpixel positioning of the antialiased letterforms, but you can cache them in that case too if you quantize the positioning, even if you don't quantize it to entire pixels
