[Qt-interest] render svg into QImage

[William Tambellini]

Happy New Year to all,

 I am rendering a svg file into a QImage.

 Here is the kind of code I have tried :

 

QSvgRenderer svgr(QString("f.svg"));

QImage i(svgr.defaultSize(), QImage::Format_RGB16 ); // I have tried nearly
all formats, QImage::Format_RGB32, QImage::Format_Indexed8,.. Without result

QPainter p(&i);

                p.setRenderHint(QPainter::Antialiasing, false);
// I have tried too to turn off SmoothPixmapTransform,
HighQualityAntialiasing, NonCosmeticDefaultPen with out result

                svgr.render(&p);             // when testing the image
pixels, there are already a lot of different colors whereas there should be
only 2 because my svg has only 1 red circle on black backgroung.

                i.save("main.bmp");      // I have tried to change quality
to 100 with no result..

 

Despite lot of trials playing with nearly all the options of Renderer, Image
and Painter, the image is STILL antialiased whereas I want a raw NON
antialiased image.

 

I tested the QPaintEngine behind and it is the "Raster" one. 

-          Cant this engine draw image WITHOUT antialliasing feature ?

-          Is it a bug ?

Regards,

WT
