Enumeration Type Documentation

ColorType

enum ColorType

This benchmark tests rendering rotated rectangles. It can optionally apply AA and/or change the paint color between each rect in different ways using the ColorType enum. The xfermode used can be specified as well.

Enumerator
kConstantOpaque_ColorType
kConstantTransparent_ColorType
kChangingOpaque_ColorType
kChangingTransparent_ColorType
kAlternatingOpaqueAndTransparent_ColorType
kShaderOpaque_ColorType
