I need to draw the content of the window to the memory context to create image for some reason. I used the example that is in the documetation - function PmMemCreateMC().
Everything works except PtPolygon and PtBezier widgets that are not drawn at all (simple window) or are drawn in wrong way (in case of window with many widgets). Sad

Does anybody have any experience ? Am I doing anything wrong ?
Thanks for any ideas.

The sample project attached.

Hmm, ... no reply yet.

I tried to draw to the OffScreenContext. It works properly. So I guess that ?bug? is somewhere inside of the Memory context ?

However, HOW TO PUT OffScreenContext TO THE IMAGE AND THEN TO WRITE IT TO THE FILE ? The application should work on the background without any change of the screen.

Thanks in advance for any help.
