示例1: updateImageViewport
bool RenderSVGImage::updateImageViewport()
{
SVGImageElement* image = toSVGImageElement(element());
FloatRect oldBoundaries = m_objectBoundingBox;
bool updatedViewport = false;
SVGLengthContext lengthContext(image);
m_objectBoundingBox = FloatRect(image->xCurrentValue().value(lengthContext), image->yCurrentValue().value(lengthContext), image->widthCurrentValue().value(lengthContext), image->heightCurrentValue().value(lengthContext));
// Images with preserveAspectRatio=none should force non-uniform scaling. This can be achieved
// by setting the image's container size to its intrinsic size.
// See: http://www.w3.org/TR/SVG/single-page.html, 7.8 The ‘preserveAspectRatio’ attribute.
if (image->preserveAspectRatioCurrentValue().align() == SVGPreserveAspectRatio::SVG_PRESERVEASPECTRATIO_NONE) {
