Hi,

Are you using Windows, right? I have noticed that kind of errors in Windows for a while now but didn't have time to investigate it since in Linux the same wxWidgets functions for screen capture work nice. I think it has to do with Windows hardware graphics acceleration.

I don't have time to do an in depth research on the problem so, please, if you do some research and find a way to disable it to allow capturing in Windows let us know here. It's the same problem that does not allow taking screenshots from a video player, etc.
Or if you find any reference about how to solve the problem from the programmatic point of view (which API to use for screen capture,...) please let me know as well so I can modify MRPT sources accordingly.

Thanks.

Hi ,

Thanks for your quick answers !
I am actually developing on Windows and you gave me the solution !
By just changing the window thema from aero ( window 7) to classic, the problem has been solved. It seems to be actually related to Windows Hardware Acceleration.
Unfortunately I can't give a programmatic solution ( no time too to go in depth in this problem ).
Hope this temporary solution could help.

Thanks , you saved me a lot of time !
