OK, so using the METAFILE device to generate WMF files. That makes this
a Windows-only issue. Before you bother asking, I don't use PostScript
because I never used a version of IDL prior to 5.6, so I've always had
the METAFILE device, which works quite well and on WIndows I can very
handily see and use the results, much more easily IMHO than PS.
Now, filled contours with 200 levels produce metafile output composed
of lots of polygons. I am using CONTOUR,/FILL for shaded display of a
dataset.
Each of those polygons, in the resulting METAFILE .WMF file, has a
border, which is a black hairline. This has no analog in the graphical
display.
I found a way to remove these with Illustrator, but it's a real hassle.
Does anyone use METAFILE enough to think if there might be a hack to
get rid of this? Do people think this might be called a bug? Since I
don't know how the PS driver handles this, I'm not sure what to expect.

What version of IDL are you using? This was a problem for IDL 6.0 and
prior, but it was fixed in IDL 6.1.
