       <item value="A description of a color filter to apply when drawing a shape or compositing a layer with a particular [Paint]. A color filter is a function that takes two colors, and outputs one color. When applied during compositing, it is independently applied to each pixel of the layer being drawn before the entire layer is merged with the destination. Instances of this class are used with [Paint.colorFilter] on [Paint] objects." />

Transparency is supported. The PNG format supports images up to 2,147,483,647 pixels in either dimension, though in practice available memory provides a more immediate limitation on maximum image size." />
