示例1:
void
LayerManagerOGL::SetWorldTransform(const gfxMatrix& aMatrix)
{
NS_ASSERTION(aMatrix.PreservesAxisAlignedRectangles(),
"SetWorldTransform only accepts matrices that satisfy PreservesAxisAlignedRectangles");
NS_ASSERTION(!aMatrix.HasNonIntegerScale(),
"SetWorldTransform only accepts matrices with integer scale");
mWorldMatrix = aMatrix;
}示例2: LOGD
bool
HwcComposer2D::TryRender(Layer* aRoot,
const gfxMatrix& aGLWorldTransform)
{
if (!aGLWorldTransform.PreservesAxisAlignedRectangles()) {
LOGD("Render aborted. World transform has non-square angle rotation");
return false;
}
MOZ_ASSERT(Initialized());
if (mList) {
mList->numHwLayers = 0;
mHwcLayerMap.Clear();
}
if (mPrepared) {

}
// XXX: The clear() below means all rect vectors will be have to be
// reallocated. We may want to avoid this if possible
mVisibleRegions.clear();
