Tank you i know that. To print on paper it's enough, but, to put on keynote slides for a meeting, the quality is to bad.

Usually it's the other way round: Print needs a higher resolution than on-screen. If you make a system screenshot (CMD+SHIFT+4) it has the full screen resolution. You cannot show more, even if an image has higher resolution. It rather might degrade the quality due to scaling.

I don't know, if my observation is related to the Win10 problem since I'm on OS X. But I also don't get any picture saved. Instead I get an error message on the console, where I started FreeCAD from:

Code: Select all

<unknown exception traceback><type 'exceptions.RuntimeError'>: Cannot save null image.

Once again: have you read the whole topic, and tried the solutions proposed here?

Yes, I did. None of the proposed parameters or environment variables solved the problem.
