What would be the best way to capture GLCtrl(or even screen) pixels into ImageBuffer?
There is a demo GrabDesktop(or something like that), but it's just for win32(gdi) and it's too slow,
i think it's using SysInfo as main capturer(Snap_DesktopRectangle,etc).
I tried using glReadPixels(0,0,xs,ys,GL_BGRA_EXT,GL_UNSIGNED_BYTE,~ib);
but i always get an error 1282. Also tried GL_BGRA and GL_RGBA, the same thing.
This would be probably the best way, or is there a better one,
eg upp-ish one?
