示例1: computeIntrinsicSizingInfo
void LayoutImage::computeIntrinsicSizingInfo(
IntrinsicSizingInfo& intrinsicSizingInfo) const {
LayoutReplaced::computeIntrinsicSizingInfo(intrinsicSizingInfo);
// Our intrinsicSize is empty if we're laying out generated images with
// relative width/height. Figure out the right intrinsic size to use.
if (intrinsicSizingInfo.size.isEmpty() &&
m_imageResource->imageHasRelativeSize()) {
LayoutObject* containingBlock =
isOutOfFlowPositioned() ? container() : this->containingBlock();
if (containingBlock->isBox()) {
LayoutBox* box = toLayoutBox(containingBlock);
intrinsicSizingInfo.size.setWidth(box->availableLogicalWidth().toFloat());
intrinsicSizingInfo.size.setHeight(
box->availableLogicalHeight(IncludeMarginBorderPadding).toFloat());
}
}
// Don't compute an intrinsic ratio to preserve historical WebKit behavior if
// we're painting alt text and/or a broken image.
// Video is excluded from this behavior because video elements have a default
// aspect ratio that a failed poster image load should not override.
if (m_imageResource && m_imageResource->errorOccurred() && !isVideo()) {
intrinsicSizingInfo.aspectRatio = FloatSize(1, 1);
return;
