QSvgRenderer onto QImage with antialiasing

**dolevo** · 18th July 2013, 14:15

Hi,

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

Qt Code:

Switch view

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;
    }

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;
    }

To copy to clipboard, switch view to plain text mode

However, the painted image is aliased and I want to have an anti-aliased image. I have tried setRenderHints() but didnâ€™t help. Could anyone help me about how to implement it?
