Undocumented roRegion Services ?
Apparently you can create an roRegion using the roScreen as its source bitmap, although the resolution/scaling is off. It also appears that roRegion exposes an ifDraw2d interface , resolving it perhaps by calling it's source objects ifDraw2d interface. I created an roRegion using roScreen as its source and then called the (non-documented)
roRegion.DrawObject, roRegion.DrawRect , all of which appears to work. (I don't see any of this documented, but did come across a post on this forum). I am particularly interested in creating regions right from the roScreen buffer which apparently works except for the scaling that is returned. I have not played with any of the pretranslation or scaling flags or rendering functions to see if I could fix it. Any light on this ??? it could possibly help those of us struggling with memory issues. Now I tried all this while a compositor was sitting on top of the screen so I don't know if I would have had different results without the compositor. But before I continue experimenting, I would like some feedback if possible. Perhaps there is some other documentation that I should be looking at
