Detailed Description

A Layer which just renders a solid color in its visible region.

It actually can fill any area that contains the visible region, so if you need to restrict the area filled, set a clip region on this layer.

Member Function Documentation

virtual void mozilla::layers::ColorLayer::ComputeEffectiveTransforms ( const gfx3DMatrix aTransformToSurface  )  [inline, virtual]
Parameters:
aTransformToSurface the composition of the transforms from the parent layer (if any) to the destination pixel grid.

Computes mEffectiveTransform for this layer and all its descendants. mEffectiveTransform transforms this layer up to the destination pixel grid (whatever aTransformToSurface is relative to).

We promise that when this is called on a layer, all ancestor layers have already had ComputeEffectiveTransforms called.

Implements mozilla::layers::Layer.

virtual const gfxRGBA& mozilla::layers::ColorLayer::GetColor (  )  [inline, virtual]
virtual LayerType mozilla::layers::ColorLayer::GetType (  )  const [inline, virtual]

) [protected, virtual]

Reimplemented from mozilla::layers::Layer.

virtual void mozilla::layers::ColorLayer::SetColor ( const gfxRGBA aColor  )  [inline, virtual]

CONSTRUCTION PHASE ONLY Set the color of the layer.
