QSvgRenderer onto QImage with antialiasing

Hi,

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

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->setRenderHints(QPainter::Antialiasing, true);
        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?

I would start by rendering the SVG after you set the Antialiasing hint.

BTW: neither the QPainter nor the QSvgRenderer needs to allocated on the heap.

I have already tried it but no joy.

I have found another thread in this forum http://www.qtcentre.org/threads/2327...r-antialiasing
However, I didn't get what he meant. I did try painting onto QPixmap but the image is still aliased.

Any help?
