Hi folks,
can anyone tell me if it's possible to draw a texture that already exists on the graphics card, without having to transfer it to the CPU-side, when in a GeUserArea()?
Currently, I pull the texture, then transfer the data to a BaseBitmap, then do this in DrawMsg():
void MyUserArea::DrawMsg(LONG x1,LONG y1,LONG x2,LONG y2,const BaseContainer &msg) { SetClippingRegion(x1,y1,x2,y2); OffScreenOn(); DrawSetPen(COLOR_BG); DrawRectangle(x1,y1,x2,y2); if(texture) { DrawBitmap(texture,Left,Top,Right,Bottom,0,0,texture->GetBw(),texture->GetBh(),BMP_NORMAL); } }
but it's very slow once the texture gets above HD desktop size. Is there a hack I can use to just draw what I've already got in GPU memory? Is there something like a BaseDraw object I can tap into here from inside the DrawMsg() method?
WP.
hi,
sorry, but with the classic API it's not possible.
Cheers, Manuel
