I assume you've tried changing the precision? Apart from that, there's not
much else you can do with OBP. You could try writing your own colour matching
routine and then use ObtainPen to lock it.

Well, it just used ObtainBestPen, so you'd probably get the same results with
my code.

Use the remap routine to remap it and then just alter the NIBDrawImage routine
so that instead of drawing to a Window, it draws to a rastport. You can easily
set up a rastport to point to a Blitz bitmap, or even a shape (via
ShapesBitMap).
InitRastPort_ &rp.RastPort
rp.BitMap = Addr BitMap(0)
; You can now draw to the Blitz bitmap through the rp rastport
