Rotating objects with svg image leads to bitmap conversion

Post by moto3101 »

Hello together,

I recently came across a very interesting problem. If you fill e.g. a rectangle with a vector image and rotate it by a custom angle, the vector graphic looks like a low quality bitmap. Even with anti-aliasing turned on, the image looks unprofessional.

I assume the image is internally mapped to a bitmap and is then rotated and displayed.

Is there something we can do about it?

I attached two pictures showing the problem:

Thanks in advance and with best regards,

If an SVG image is loaded it is transformed into a pixmap using QT functions.
When rotating the image redrawing the image is made by QT functions.
Using AntiAliasing has no effect in this case.

Right now the behaviour cannot be changed.
