Graphical modes of QEMU

[Ant_222]

Hello all,

I have started using Q and am wondering whether it can work at another scale than pixel-to-pixel in windows mode. For small resolutions in the guest OS it would be really handy to have an option for 2x, 3x, 4x,... scales, so that the picture would not be garbled and would not require any kind of interpolation and yet would not be too small (for example, most of ZX Spectrum emulators offer this option, because at the pixel-to-pixel scale everything looks downright microscopic).

Additionally, I am really disappointed with the full-screen mode. It looks like there's no interpolation. Is there a way to use some interpolation or an integer scale that would keep the picture undistorted in the full-screen mode (possible leaving some black margins)?

Thanks in advance,
Anton

++: One of the options for graphical output is OpenGL, which certainly has fast functions for such rescaling...

Few special device drivers (graphics, sound, IO) for guests are available, thus quite large overhead for multimedia applications. For example, a Cirrus Logic graphics chip and various popular sound cards (ES1370, Sound Blaster 16, Gravis Ultrasound and AdLib) are emulated, but they do not provide hardware-accelerated performance on the host system.
