Set proper RenderHints for better Image Scaling

[g1plus]

Scaled images (especially upscaled) are poorly interpolated (nearest neighbor?). CutyCapt should set (or allow through flags to set) renderhints to circumvent this.

Simple hack:

painter.begin(&image);
painter.setRenderHint(QPainter::SmoothPixmapTransform);
painter.setRenderHint(QPainter::Antialiasing);
painter.setRenderHint(QPainter::TextAntialiasing);
painter.setRenderHint(QPainter::HighQualityAntialiasing);
mainFrame->render(&painter);

I have tried this a couple of times on Windows, most recently with the current version of Qt 5.x for that system, and it had no effect that I could discern. Have you tried this, and on what kind of system?

I tried it under linux (Arch Linux x64, qt5) because I ran into this problem when using the CSS-property background-size: cover You can try: CutyCapt --url=http://webstandard.kulando.de/static/backgroundsize-css-tutorial --out=jagged.png --min-width=1920

I attached two images, with and without RenderHints

hoehrmann, how we can create CutyCapt.exe file in windows machine?
