I think I'm where I need to go. It appears that most of the problems were related to the EPS file. I was able to go back to our source and export a JPG. Transformation using that came out cleaner and maintained the line weights.

Thank you for your help. Hopefully my future postings, if there are any, will be clearer from the get go.

Note JPG is a lossy format, so it is possible your lines may not look the best. Have you tried PNG or TIFF? I still don't know why GIF does not work.

To clarify, I'm still outputting a GIF. I'm just starting with a JPG instead of an EPS. It appears that there was a problem with Imagemagick recognizing the line size from the original EPS.

You do realise that you are trying to do you 'fuzz' color matching to a CMYK image?

Add a -colorspace RGB and all should work fine!



PS: to preserve anti-aliasing use a -density -resample technique on the SVG.

convert -density 288 Sample.eps -resample 72 -colorspace RGB show:

However you want GIF, are you really wanting GIF transparency too?
GIF transparency is purely boolean. That is only ON and OFF, and it looks horrible!
PNG may be better!

convert -density 288 Sample.eps -resample 72 -colorspace RGB \
-normalize -negate -background black -alpha shape show:

With your help I finally got the GIF where I think I need it (still awaiting for approval). In regards to GIF, I didn't pick nor would I if I had a choice. When I was first asked I immediately asked about PNG instead and was told no. Funny part is that yesterday they said that was a fall-back file type. Oh well.

Thanks for your help.
