示例1: currentScale
float SVGSVGElement::currentScale() const
{
if (!inDocument() || !isOutermostSVG())
return 1;
Frame* frame = document()->frame();
if (!frame)
return 1;
FrameTree* frameTree = frame->tree();
ASSERT(frameTree);
// The behaviour of currentScale() is undefined, when we're dealing with non-standalone SVG documents.
// If the svg is embedded, the scaling is handled by the host renderer, so when asking from inside
// the SVG document, a scale value of 1 seems reasonable, as it doesn't know anything about the parent scale.
return frameTree->parent() ? 1 : frame->pageZoomFactor();
}示例2: setCurrentScale
void SVGSVGElement::setCurrentScale(float scale)
{
if (!inDocument() || !isOutermostSVG())
return;
Frame* frame = document()->frame();
if (!frame)
return;
FrameTree* frameTree = frame->tree();
ASSERT(frameTree);
// The behaviour of setCurrentScale() is undefined, when we're dealing with non-standalone SVG documents.
// We choose the ignore this call, it's pretty useless to support calling setCurrentScale() from within
// an embedded SVG document, for the same reasons as in currentScale() - needs resolution by SVG WG.
if (frameTree->parent())
return;
frame->setPageZoomFactor(scale);
