Re: Problems with filled EPS files in Illustrator

Hi Adam,

I finally got to your latest suggestion this morning, and while it worked,
it also did not preserve the graphic in vector format and the graphic
becomes pixelated at any increased zoom level. This pixelation is evident
in any graphics viewer and appears to be the product of the rasterization
of the image.

In the original link, you can see NCL's .ps file (subtrop_map_fill.ps), the
file run directly through convert (subtrop_map_fill_NEW.ps), and my attempt
to convert the .eps to .ps (subtrop_map_PS.ps). The last of these three
decreased the file size the greatest, but led to a similar non-vector
format as the original .ps to .ps conversion. Finally, the original .ps
file from NCL is also not openable by AI.

I've also done a comparison on a different system with NCL 6.1.2 and a
newer version of convert (6.7.9-10 vs. the 6.5.4-7 version on my original
machine) with no apparent difference in the results.

Knowing that this works fine with PDF output, I'm not sure if it's worth
pursuing this seeming incompatibility, but it is interesting to note that
Illustrator does have this problem.
