flatten()

void SkRecordedDrawable::flatten ( SkWriteBuffer &  ) const

overridevirtual

Override this if your subclass needs to record data that it will need to recreate itself from its CreateProc (returned by getFactory()).

DEPRECATED public : will move to protected ... use serialize() instead

Reimplemented from SkFlattenable.

onMakePictureSnapshot()

sk_sp< SkPicture > SkRecordedDrawable::onMakePictureSnapshot ( )

overrideprotectedvirtual

Default implementation calls onDraw() with a canvas that records into a picture. Subclasses may override if they have a more efficient way to return a picture for the current state of their drawable. Note: this picture must draw the same as what would be drawn from onDraw().
