I need to transfer the image from a dummy BMP canvas to paintbox
canvas here is my code :

  bitblt(DispRec.WorkCanvas.handle,0,0,DispRec.CnvW,DispRec.CnvH,Dummy
Bmp.Canvas.Handle,0,0,SRCpaint) ;  

it works for windows platform but doesn't work for linux ,if I change
Rop to SRCcopy they all works, but i need Srcpaint modenwork for linux

can anyone tell me what is going on?

Probably not implemented. BitBlt has to may different modes to be
emulated on non windows platforms
(otoh, a generic ROP bits based implementation should be doable, but
first some rewrites)
