bool SkBlurDrawLooper::BlurDrawLooperContext::next ( SkCanvas *  canvas, SkPaint *  paint  )

overridevirtual

Called in a loop on objects returned by SkDrawLooper::createContext().

Each time true is returned, the object is drawn (possibly with a modified canvas and/or paint). When false is finally returned, drawing for the object stops.

On each call, the paint will be in its original state, but the canvas will be as it was following the previous call to next() or createContext().

The implementation must ensure that, when next() finally returns false, the canvas has been restored to the state it was initially, before createContext() was first called.

Implements SkDrawLooper::Context.
