Herbie, Pierre and others, A treacherous tailwind blowing in the direction of PDF has been encountered by many. And unfortunately I have not yet solved several problems regarding working with, and going to/from PDF. I agree that the pricey Illustrator is fairly good at importing and exporting numerous other formats. But few of your your collaborators will have it. For me *batch* conversions of high precision bitmaps to/from PDF have been elusive. They haven't worked with Illustrator. (But maybe there is a plugin for that?) However a friend suggested that Open Office(=OO) may offer some good batch solutions. Here is his recipe for extracting 'all' the bitmaps from one PDF file. > 1. Load the PDF file into OO. > 2. Save current document as ODF Drawing (*.ODG). > 3. Close document. > 4. Rename *.ODG file as *.ZIP. > 5. Unzip *.ZIP ---> all pages at once I get all PNG and TIFF-G4 graphics it seems. Intact. But not yet JPG... . I abhore the hazy JPGs that T.Lemke's GraphicsConverter imports from PDF. There's hope of going the other way using OO, since the ODG (=Open Office Graphics) format is an XML and more modern than PDF. If anyone has deeper knowlege of ODG, I'll be listening. What about iWork's "Pages" application in place of Open office? Another tack:- Metapost is a pretty good 2-dim, programmable, vectorial, graphics language, from which one can get to PDF. It is by John Hobby. Pierre could probably have his FB programs write metapost files. There's a distribution of Metapost in A. Trevorrow's OzTeX: http://www.trevorrow.com/oztex/#sysreq It outputs PS and EPS, from which one can get to PDF. Comments? Laurent S.
