We are currently creating an .idr file in Isodraw. We then export it to jpg and to cgm. The jpg is so you can see what the end result looks like and the cgm is put in a different folder where the manual is located. We then create a link in editor to the cgm, so it can be used in the manual. It seems that when you publish, every cgm is then converted to eps. Would we be better off using the idr files, instead of creating cgms??
We used jpg in our documentation but the result was not ideal, so now we use eps but more often tif files. The eps sometimes disappears when generating PDF, Arbotext may have issues to handle vectorised files.
I use Arbortext Editor with styler to generate my PDF files and I use Adobe Illustrator to create and edit illustrations. The issue with eps is specific to my working condition, I get some eps from my japanese colleagues and it is really heavy and highly vectorised with a lot of layers. Because of that sometimes the Editor does not generate the eps illustration in my PDF.
My solution so far is to work with illustrator to create and edit eps before to export the eps to a tiff file. I handle two library of illustrations, one in eps and one in tiff.
I use PNG for web output and EPS for PDF output. I include both formats in my dita files for multi-channel publishing. You can exclude one in the output using Profiling or a ditaval file.
