示例1: embeddedContentBox
LayoutBox* SVGImage::embeddedContentBox() const
{
SVGSVGElement* rootElement = svgRootElement(m_page.get());
if (!rootElement)
return nullptr;
return toLayoutBox(rootElement->layoutObject());
}示例2: setContainerSize
void SVGImage::setContainerSize(const IntSize& size)
{
SVGSVGElement* rootElement = svgRootElement(m_page.get());
if (!rootElement)
return;
FrameView* view = frameView();
view->resize(this->containerSize());
LayoutSVGRoot* layoutObject = toLayoutSVGRoot(rootElement->layoutObject());
if (!layoutObject)
return;
layoutObject->setContainerSize(size);
}示例3: containerSize
IntSize SVGImage::containerSize() const
{
SVGSVGElement* rootElement = svgRootElement(m_page.get());
if (!rootElement)
return IntSize();
LayoutSVGRoot* layoutObject = toLayoutSVGRoot(rootElement->layoutObject());
if (!layoutObject)
return IntSize();
// If a container size is available it has precedence.
IntSize containerSize = layoutObject->containerSize();
if (!containerSize.isEmpty())
return containerSize;
// Assure that a container size is always given for a non-identity zoom level.
ASSERT(layoutObject->style()->effectiveZoom() == 1);
FloatSize intrinsicSize;
double intrinsicRatio = 0;
layoutObject->computeIntrinsicRatioInformation(intrinsicSize, intrinsicRatio);
if (intrinsicSize.isEmpty() && intrinsicRatio) {
if (!intrinsicSize.width() && intrinsicSize.height())
intrinsicSize.setWidth(intrinsicSize.height() * intrinsicRatio);
else if (intrinsicSize.width() && !intrinsicSize.height())
intrinsicSize.setHeight(intrinsicSize.width() / intrinsicRatio);
}
// TODO(davve): In order to maintain aspect ratio the intrinsic
// size is faked from the viewBox as a last resort. This may cause
// unwanted side effects. Preferably we should be able to signal
// the intrinsic ratio in another way.
if (intrinsicSize.isEmpty())
intrinsicSize = rootElement->currentViewBoxRect().size();
if (!intrinsicSize.isEmpty())
return expandedIntSize(intrinsicSize);
// As last resort, use CSS replaced element fallback size.
return IntSize(300, 150);
