示例1: computeImageViewportSize
FloatSize LayoutSVGImage::computeImageViewportSize(ImageResource& cachedImage) const
{
if (toSVGImageElement(element())->preserveAspectRatio()->currentValue()->align() != SVGPreserveAspectRatio::SVG_PRESERVEASPECTRATIO_NONE)
return m_objectBoundingBox.size();
// Images with preserveAspectRatio=none should force non-uniform
// scaling. This can be achieved by setting the image's container size to
// its viewport size (i.e. if a viewBox is available - use that - else use intrinsic size.)
// See: http://www.w3.org/TR/SVG/single-page.html, 7.8 The 'preserveAspectRatio' attribute.
Length intrinsicWidth;
Length intrinsicHeight;
FloatSize intrinsicRatio;
cachedImage.computeIntrinsicDimensions(intrinsicWidth, intrinsicHeight, intrinsicRatio);
return intrinsicRatio;
