示例1: AccumulateRectDifference
void
DisplayItemClip::AddOffsetAndComputeDifference(uint32_t aStart,
const nsPoint& aOffset,
const nsRect& aBounds,
const DisplayItemClip& aOther,
uint32_t aOtherStart,
const nsRect& aOtherBounds,
nsRegion* aDifference)
{
if (mHaveClipRect != aOther.mHaveClipRect ||
aStart != aOtherStart ||
mRoundedClipRects.Length() != aOther.mRoundedClipRects.Length()) {
aDifference->Or(*aDifference, aBounds);
aDifference->Or(*aDifference, aOtherBounds);
return;
}
if (mHaveClipRect) {
AccumulateRectDifference(mClipRect + aOffset, aOther.mClipRect,
aBounds.Union(aOtherBounds),

}
for (uint32_t i = aStart; i < mRoundedClipRects.Length(); ++i) {
if (mRoundedClipRects[i] + aOffset != aOther.mRoundedClipRects[i]) {
// The corners make it tricky so we'll just add both rects here.
aDifference->Or(*aDifference, mRoundedClipRects[i].mRect.Intersect(aBounds));
aDifference->Or(*aDifference, aOther.mRoundedClipRects[i].mRect.Intersect(aOtherBounds));
