virtual bool Blur_Layer::reads_context | ( | ) | const [inline, virtual] |
Returns true if the layer needs to be able to examine its context.
context to render itself, other than for simple blending. For example, the blur layer will return true - it can't do its job if it can't see its context, and the circle layer will return false - rendering a circle doesn't depend on the underlying context until the final blend operation.
