# drawDibToDib

Definition: | drawDibToDib(a32Dib destdib, a32Dib srcdib, integer dX, integer dY, integer sX1, integer sY1, integer sX2, integer sY2, sequence trans_color, integer alpha)
Description: | Draws portion {sX1, sY1} -> {sX2, sY2} of dib_src to the bitmap dib_dest at position {dX, dY}.
Comments: | The trans_color parameter is the transparent color. The pixels from src that have a color equal to trans_color are not drawn. If trans_color is an empty sequence, no transparency is used. alpha is the translucency value: 0 = completely transparent, 255 = completely opaque. (The drawTransDibToDib-procedure does not exist anymore: the transparency-functionality has been implemented in drawDibToDib).
