[comp.soft-sys.andrew] How to make zip much more reliable.

wdc@ATHENA.MIT.EDU (Bill Cattey) (04/11/90)

I (and many others, no doubt) have had the frustrating experience of
trying to do close work with zip and having it seem to ignore or mis-do
the commands I specify.

I thought this was because of some terrible bug deep inside the system
that was causing mouse motion to be mis-processed.

It turns out that it's a preference that is set to a very different
default than my expectation:

ZipCreateTolerance

The default is 10.  This means that if I try to continue a polygon
within 10 pixels of the previous point, I can't.  I have just tested the
preference:

*.ZipCreateTolerance: 0

in global.prf, and zip is MUCH nicer to me.  Even tickling arcs is easier.

I strongly recomment that further testing be done, with an eye to making
zero the default value.
