searched on the forums but I didn't get anything...
Just need to check.
You put 'imagebuffer' or 'imagebuffers' into the Blitzmax forum search and nothing came back?
There are quite a few solutions although nothing I would consider 'nice'. Since Indiepath's RTT module isn't working at 1.24 and HighGfx has disappeared for OGL the best solution is either pixmap.paste for no-alpha or memcopy (I have something in the code archive which does it) or draw/grab which is slow.
I might look at this again but I'm still gobsmacked that BRL have no interest in providing it.
