C++ (Cpp) adjustRectsForAspectRatio Examples

Example #1

void RenderSVGImage::paint(PaintInfo& paintInfo, int, int)
{
    if (paintInfo.context->paintingDisabled() || style()->visibility() == HIDDEN)
        return;

    paintInfo.context->save();

        PaintInfo savedInfo(paintInfo);

        prepareToRenderSVGContent(this, paintInfo, m_localBounds, filter);

        FloatRect destRect = m_localBounds;
        FloatRect srcRect(0, 0, image()->width(), image()->height());

        SVGImageElement* imageElt = static_cast<SVGImageElement*>(node());
        if (imageElt->preserveAspectRatio()->align() != SVGPreserveAspectRatio::SVG_PRESERVEASPECTRATIO_NONE)
            adjustRectsForAspectRatio(destRect, srcRect, imageElt->preserveAspectRatio());
