Afterwards 'convert' encapsulates the bitmap image into a PDF. I agree that from an end-user point of view "It would be very nice if the different conversion methods could give the same results all the way through the display and printing stages in different computers" but the present situation is that there is neither such a thing as a general guideline or specification nor is there a general agreement which same result all those different conversion methods should give. As matters stand the different conversion tools are made by different open source software projects with different use-cases in mind where each has its own reasoning behind what each particular default behaviour is. I am not involved in the ImageMagick open source software project so that I cannot decide about the 'convert' default behaviour. According to http://www.imagemagick.org "ImageMagick is a software suite to create, edit, compose, or convert bitmap images." That means the primary focus are bitmaps (and not vector graphics like PostScript usually has) and I assume that for bitmaps the 'convert' default behaviour is best. In contrast the main focus of Ghostscript is PostScript and PDF in particular regarding printing output so that the 'ps2pdf' default behaviour fits better for printing output. Bottom line from my point of view: Regardless that 'convert' works to convert PS/EPS into PDF it is not the best tool for it because it is meant to work with bitmap images. In contrast 'ps2pdf' is primarily meant to convert PS/EPS into PDF. I close the issue again as "invalid" because there is no actual bug. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
