Identify and Freehand EPS containing spot colors

I have some trouble retrieving the right colorspace value from EPS files exported with Freehand MX. Identify always shows RGB, even though the file has CMYK colors (or PMS spot colors). Also, would it be possible to retrieve a list of spot colors from EPS files with identify? This seems to work at least with PDF files in the latest IM release. Identify outputs the correct colorspace for EPS files exported with InDesign or Illustrator.
Here's the Freehand EPS file.

i have similar problems with pdf files.
The file on
http://softwareftp.dig.de/pdfs/pdf_cmyk_rgp.pdf is detected as RGB image but contains a CMYK rectangle.

ImageMagick cannot always detect the colorspace of a PDF image. You can always force a colorspace with the
-colorspace option:
- convert -colorspace CMYK pdf_cmyk_rgp.pdf image.png
However, with a patch we can detect CMYK EPS images. We put a patch in ImageMagick 6.3.2-0 Beta, available sometime tomorrow. Thanks for the problem report.

Thank you very much for your quick reply & patch regarding CMYK EPS colorspace identification. How about retrieving spot color ID:s from an EPS file similar to PDF:s, is this possible?

You know the drill. Post a URL to a few EPS images with spotcolors and point us to the specification and we'll get a patch into ImageMagick to recognize the spotcolor names in EPS.

Ok.
Freehand EPS with spot colors
Contains spot information such as:
Code: Select all
%%DocumentCustomColors: (PANTONE 1775 C)
%%+ (PANTONE 7437 C)
%%+ (PANTONE 568 C)
Contains spot information such as:
Code: Select all
%%DocumentCustomColors: (PANTONE 568 C)
%%+ (PANTONE 7437 C)
%%+ (PANTONE 1775 C)
So I suppose one could retrieve a list of spot colors with identify based on these values. Hope this helps.
