That's right, but the resolution loss is very minor for these cases. > > > OO.o failed with the conversion -- parts of the image do not appear in > > the output file -- as did conversion with ImageMagick. > > Did you use the "+repage" option of ImageMagick?

The image is flattened, so I do think the image should be all on one canvas. But I am certainly not familiar with the details of the program, and one of those how is how they count what is in that canvas or not. > In general, it is rather pointless to request that > groff -Tps accepts images in formats other than EPS > since it would have to convert them internally to > a representation effectively identical to EPS in any > case.

Any idea why groff could not accept an eps file generated by Acrobat? I would have thought that Adobe's own product would turn out proper code. Frank
