If you look at the EPS it specifies a 235x235 bounding box, and a scale factor to shoehorn the diagram in it. the page.eps file that i am using has: %%BoundingBox: -1 -1 234 234 and identify says both the eps and convert gif are 235 by 235. gimp says the eps is 236 by 236 when i import it. If you edit the EPS to work with a 1:1 scale and a sufficient bounding box (2 lines to edit, no hard to script), the output of convert is OK. what should the values be for bounding box? can you show me the values that you used and the convert command that had the great result? thanks --- co-chair http://ocjug.org/ ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user
