[comp.sys.amiga.tech] Rastport & Bitmap

tron1@tronsbox.xei.com (HIM) (10/01/90)

For some animation work I have to do , I need to make a new RastPort the
same size and depth etc as the rastport for a window I have. Now, the
question is ...

    To make the new RastPort I need to make a new BitMap ... can I
    just copy the entries of the old_rast->BitMap structure to the
    new one , allocate new planes for the planeptr array and be
    all set ? IOr does InitBitMap do something special ??

	InitBitMap is fairly straightforward currently, but it may not be
in the future.  For maximum compatibility, I would encourage you to use it
if possible.
