Comment 4 for bug 548918

Alvin,

the resolution option works correctly, thanks very much.

There are a couple of other issues with the hpgl output. I'm not sure
whether they warrant another bug report or not:

Firstly, the hpgl files generated by this extension leave the pen in
the down state at the end of the file. It would be useful if it issued
a pen up command at the end. Without this, the ink from the pen begins
to soak into the paper and bleeds into a blob at the last point
plotted. The pen up command is 'PU;'

Secondly, every hpgl file generated by the extension begins by
selecting pen 1, and generating the entire output with this pen. It
might be more useful to have an option in the save-as dialog that
specifies which pen to select, or to select a different pen for each
layer. This doesn't matter for folks who use hpgl files for a vinyl
cutter, as they do not have multiple pens. But plotters typically have
multiple pens. Mine has 6 pens, and 8 pens is also common.
