◆ SkCoverageMode

strong

Describes geometric operations (ala SkRegion::Op) that can be applied to coverage bytes.

These can be thought of as variants of porter-duff (SkBlendMode) modes, but only applied to the alpha channel.

See SkMaskFilter for ways to use these when combining two different masks.
