示例1: containerSize
IntSize SVGImage::containerSize() const
{
SVGSVGElement* rootElement = this->rootElement();
if (!rootElement)
return IntSize();
auto* renderer = downcast<RenderSVGRoot>(rootElement->renderer());
if (!renderer)
return IntSize();
// If a container size is available it has precedence.
IntSize containerSize = renderer->containerSize();
if (!containerSize.isEmpty())
return containerSize;
// Assure that a container size is always given for a non-identity zoom level.
ASSERT(renderer->style().effectiveZoom() == 1);
FloatSize currentSize;
if (rootElement->hasIntrinsicWidth() && rootElement->hasIntrinsicHeight())
currentSize = rootElement->currentViewportSize();
else
currentSize = rootElement->currentViewBoxRect().size();
if (!currentSize.isEmpty())
return IntSize(static_cast<int>(ceilf(currentSize.width())), static_cast<int>(ceilf(currentSize.height())));
// As last resort, use CSS default intrinsic size.
return IntSize(300, 150);
}示例2: computeReplacedLogicalWidth
LayoutUnit RenderSVGRoot::computeReplacedLogicalWidth(ShouldComputePreferred shouldComputePreferred) const
{
SVGSVGElement* svg = toSVGSVGElement(node());
ASSERT(svg);
// When we're embedded through SVGImage (border-image/background-image/<html:img>/...) we're forced to resize to a specific size.
if (!m_containerSize.isEmpty())
return m_containerSize.width();
if (isEmbeddedThroughFrameContainingSVGDocument())
return containingBlock()->availableLogicalWidth();
if (style()->logicalWidth().isSpecified() || style()->logicalMaxWidth().isSpecified())
return RenderReplaced::computeReplacedLogicalWidth(shouldComputePreferred);
if (svg->hasIntrinsicWidth())
return resolveLengthAttributeForSVG(svg->intrinsicWidth(), style()->effectiveZoom(), containingBlock()->availableLogicalWidth().toFloat());
// SVG embedded via SVGImage (background-image/border-image/etc) / Inline SVG.
return RenderReplaced::computeReplacedLogicalWidth(shouldComputePreferred);
