Hi,
I would appreciate some help concerning efficient drawing of colour
PICTs on to offscreen pixmaps.
In the program I have written I load up an 8 or 24 bit PICT, create
an offscreen world using the great new GWorld calls and then draw
the PICT onto the offscreen pixmap (and its gdevice).
My only problem is the amount of memory it takes to hold both the
PICT and offscreen gworld, and then more memory to draw the PICT.
My questions:
Is less memory used if the PICT is drawn in several steps using
clipping, say a quarter of the PICT at a time?
Is there any other way to load a portion of the PICT and draw it
offscreen a bit at a time?
Thank you in advance for any words of wisdom.
Regards,
