示例1: RenderReplaced
RenderHTMLCanvas::RenderHTMLCanvas(HTMLCanvasElement& element, PassRef<RenderStyle> style)
: RenderReplaced(element, WTF::move(style), element.size())
{
// Actual size is not known yet, report the default intrinsic size.
view().frameView().incrementVisuallyNonEmptyPixelCount(roundedIntSize(intrinsicSize()));
}示例2: paintReplaced
void RenderHTMLCanvas::paintReplaced(PaintInfo& paintInfo, const LayoutPoint& paintOffset)
{
GraphicsContext* context = paintInfo.context;
LayoutRect contentRect = contentBoxRect();
contentRect.moveBy(paintOffset);
LayoutRect paintRect = replacedContentRect();
paintRect.moveBy(paintOffset);
bool clip = !contentRect.contains(paintRect);
if (clip) {
// Not allowed to overflow the content box.
paintInfo.context->save();
paintInfo.context->clip(pixelSnappedIntRect(contentRect));
}
// FIXME: InterpolationNone should be used if ImageRenderingOptimizeContrast is set.
// See bug for more details: crbug.com/353716.
InterpolationQuality interpolationQuality = style()->imageRendering() == ImageRenderingOptimizeContrast ? InterpolationLow : CanvasDefaultInterpolationQuality;
