示例1: setImage
void HTMLImageLoader::setImage(CachedImage *newImage)
{
CachedImage *oldImage = m_image;
if (newImage != oldImage) {
setLoadingImage(newImage);
m_firedLoad = true;

if (newImage)
newImage->ref(this);
if (oldImage)
oldImage->deref(this);
}
if (RenderObject* renderer = element()->renderer())
if (renderer->isImage())
static_cast<RenderImage*>(renderer)->resetAnimation();
}示例2: updateFromElement
void HTMLImageLoader::updateFromElement()

// down the raw HTML parsing case by loading images we don't intend to display.

if (!doc->renderer())
return;
