NPAPI:InvalidatingCoreAnimation: Difference between revisions

The regular Core Animation drawing model (NPDrawingModelCoreAnimation) does not work well for browser that don't hook CA layers into a layer tree. Browsers that want to read and composite data need a way to know when a plugin's pixels should be updated in order to operate efficiently. Core Animation does not allow for this.

The Invalidating Core Animation model works much like the regular Core Animation model does. See [[NPAPI:CoreAnimationDrawingModel|the regular Core Animation documentation]], which will not be duplicated here. The only difference is that when a plugin wants to draw it needs to call NPN_Invalidate and draw during the subsequent paint event.
