[comp.graphics] HPGL 7475a bug ???

michelle@pogo.WV.TEK.COM (Michelle Riddle) (09/07/89)

I have a  HP 7475A plotter, and when I change the P1 and P2 scaling
points, the relative size (SR) is automatically changed to reflect the
changes to P1 and P2, but the relative direction (DR) does not seem to be
effected by the changes to P1 and P2 unless I specifically use the DR;
command.  Then the direction is updated to reflect the new positions of
P1 and P2.  Is this a known bug?  Or am I interpreting things incorrectly?

This is causing me problems because I assume that the relative direction
is automatically updated to reflect the new position of P1 and P2 and it
is not changing !!

Thanks for any help that people might have...
