[net.micro.mac] Looking for bitmap -> MacPaint conversion

vishniac@wanginst.UUCP (Ephraim Vishniac) (04/04/85)

A colleague of mine is attempting to transfer images from a Wang
Professional Imaging Computer (PIC) to a Macintosh.  Converting from
PIC native format to a straight bitmap is easy, as is cutting rectangular
regions of the bitmap and sending them to the Mac.  Problem: neither from 
Aztec C nor from MacPascal has he been able to use PackBits successfully.

As a temporary solution, we're cutting regions of the right size for
startup screens, and using screenmaker to do the conversion to MacPaint
format.  This isn't very satisfactory, as it only gives a fraction of
a full MacPaint page.

Can someone help us out with:

	An example of PackBits use in C? (Any C will do.)

	A program that does bitmap -> MacPaint conversion on larger areas?

	An example of PackBits use in any language at all?

	The absolute ideal: source code for ScreenMaker?

Thanks in advance,
