Those aren't really applicable for this. I'm using a Canvas to draw a Path object on top of an existing ImageView. So in order to blend the pixels, I have to use a PorterDuffXferMode with the Paint object used to draw the Path. There is an issue when doing that directly on top of the ImageView though, so instead, I have to render the freeform annotation to a background bitmap, then blend the two bitmaps.
