示例1: color
static void
RenderColorLayer(ColorLayer* aLayer, LayerManagerOGL *aManager,
const nsIntPoint& aOffset)
{
if (aManager->CompositingDisabled()) {
return;
}
aManager->MakeCurrent();
// XXX we might be able to improve performance by using glClear
nsIntRect visibleRect = aLayer->GetEffectiveVisibleRegion().GetBounds();
/* Multiply color by the layer opacity, as the shader
* ignores layer opacity and expects a final color to
* write to the color buffer. This saves a needless
* multiply in the fragment shader.
*/
gfxRGBA color(aLayer->GetColor());
float opacity = aLayer->GetEffectiveOpacity() * color.a;
color.r *= opacity;
color.g *= opacity;
color.b *= opacity;
color.a = opacity;
ShaderProgramOGL *program = aManager->GetProgram(gl::ColorLayerProgramType,
aLayer->GetMaskLayer());
program->Activate();
program->SetLayerQuadRect(visibleRect);
