#355 closed defect (fixed)
ps.map generates invalid postscript when vlegend item does not appear on map

Description
I have a map control file that generates several (21) vareas with pattern fill and defines label and lpos entries for the legend. As it happens, one of those vareas does not appear on the map area. As a result, the postscript output omits the dictionary entry for that pattern. When vlegend generates the legend output, it attempts to reference the missing pattern definition (of the form APATTEPSnn) and applications that try to render the postscript fail in various ways. Workaround is to omit the vareas causing the problem. I have not included files but can provide them if needed.

patch applied in SVN, thanks!
I also fixed the vector legend bug reported by Casey Vandenberg on Nov 20 where it wouldn't let you place the vector legend to the left of the map box. Now you can go as far as the left margin. The right side of the legend (for multicolumn) is still rather unconstrained, I've left it as not starting a new column past the right side of the map box, which seems like a fair compromise. Feel free to post a patch doing that better if you can figure out how.. I don't think it is easily possible to improve on the current way.

actually it was easy. I've now added a new vlegend "span" command to let you set the legend column spacing.

Insert this line after
to ensure the pattern definition is saved.
Hope this helps.
