I have a QImage and I draw an svg image onto. Here is my simplified code:

@void WP::DrawImage(QImage &mImage)
{
QPainter *pPainter = new QPainter(&mImage);
QSvgRenderer *svgImg = new QSvgRenderer(linkToSvgImage);

QRect rct(0, 0, 500, 500);
svgImg->render(pPainter, rct);        
pPainter->end();

delete svgImg;
delete pPainter;

}
@

However, the painted image is aliased and I want to have an anti-aliased image. I have tried setRenderHints() but didn't help. Could anyone help me about how to implement it?
