[comp.sys.mac] Laserwriter dashed line problems

fdot@sphinx.uchicago.edu (Tom Lippincott) (05/15/87)

I have a program that uses picture comments to print dashed lines on the
laserwriter, as described in tech note 91.  However, as soon
as it turns on dashed lines, the laserwriter driver (3.1) suffers a strange
disorientation -- it gets the coordinates for LineTo calls *backwards*,
exchanging the horizontal and vertical coordinates.  As soon as I turn
off the dashed lines, things return to normal.  Wierd.

Extra info:  I'm using Lightspeed C, under system 3.2.

Well, I just got the new system/finder, with the 4.0 laserwriter driver,
and guess what? -- It doesn't do that any more.  Anyone know how to check
for the driver version number?
