Detailed Description

This subclass of SkPathEffect applies two pathEffects, one after the other. Its filterPath() returns true if either of the effects succeeded.

◆ Make()

inlinestatic

Construct a pathEffect whose effect is to apply two effects, in sequence. (e.g. first(path) + second(path)) The reference counts for first and second are both incremented in the constructor, and decremented in the destructor.

Definition at line 160 of file SkPathEffect.cpp.

                                                                                           {

◆ onFilterPath()

Filter the input path.

The CTM parameter is provided for path effects that can use the information. The output of path effects must always be in the original (input) coordinate system, regardless of whether the path effect uses the CTM or not.

Implements SkPathEffectBase.
