[net.micro.mac] LaserWriter and Quickdraw

djr@dciem.UUCP (Doug Ross...see Martin Tuori) (07/15/86)

We discovered a problem when we tried to print from an application
we are developing. ImageWriter output is fine but LaserWriter output
was not properly clipped. In essence the application drew two rectangles
put their regions into the clip region, then drew a line from centre-to-centere.
On the screen and the ImageWrite the segment of the line inside the rectangles
is clipped. On the LaserWriter the line shows up inside the rectangles.

We don't have any specific LaserWriter doc'n that helps us with this 
problem. Any observations/suggestions?

It is documented in a software supplement note that non-rectangular
clip regions are not implemented on the laserwriter.  Region
operations in general are not implemented.  To quote: "Simulate them
with Polygons"

I think this is a cop out.  It caused me IMMENSE pain in the you know what.
