示例1: collectRoundedRectClips
void LayerClipRecorder::collectRoundedRectClips(PaintLayer& paintLayer, const PaintLayerPaintingInfo& localPaintingInfo, GraphicsContext& context, const LayoutPoint& fragmentOffset, PaintLayerFlags paintFlags,
BorderRadiusClippingRule rule, Vector<FloatRoundedRect>& roundedRectClips)
{
// If the clip rect has been tainted by a border radius, then we have to walk up our layer chain applying the clips from
// any layers with overflow. The condition for being able to apply these clips is that the overflow object be in our
// containing block chain so we check that also.
for (PaintLayer* layer = rule == IncludeSelfForBorderRadius ? &paintLayer : paintLayer.parent(); layer; layer = layer->parent()) {
// Composited scrolling layers handle border-radius clip in the compositor via a mask layer. We do not
// want to apply a border-radius clip to the layer contents itself, because that would require re-rastering
// every frame to update the clip. We only want to make sure that the mask layer is properly clipped so
// that it can in turn clip the scrolled contents in the compositor.
if (layer->needsCompositedScrolling() && !(paintFlags & PaintLayerPaintingChildClippingMaskPhase))
break;
if (layer->layoutObject()->hasOverflowClip() && layer->layoutObject()->style()->hasBorderRadius() && inContainingBlockChain(&paintLayer, layer)) {
