Canvas - hardware acceleration possible?

PaulR · Aug 7, 2012

I was reading up on Android graphics hardware acceleration here and see that Canvas is supported. Does this mean that enabling hardware acceleration in the Manifest automagically invokes this?

I see there are unsupported Canvas functions....

When hardware accelerated, the 2D rendering pipeline supports the most commonly used Canvas drawing operations as well as many less-used operations. All of the drawing operations that are used to render applications that ship with Android, default widgets and layouts, and common advanced visual effects such as reflections and tiled textures are supported. The following list describes known operations that are not supported with hardware acceleration:

Canvas
clipPath()
clipRegion()
drawPicture()
drawTextOnPath()
drawVertices()

... but are the rest supported in b4a or would it be possible to implement hardware acceleration for simple canvas DrawLine and DrawRect operations in another way?

GameView is based on an hardware accelerated canvas: GameView - Create 2D Android games - Part I

The accelerated canvas is only available as part of the views drawing cycle. It cannot be used like a standard canvas.

ABExtDrawing library will you access to those missing functions
