White III > Head of St. Margarets Bay, Nova Scotia, Canada Having checked the pdfTeX documentation, doesn't the internal parameter \pdfcompresslevel deal with this? The documentation says: "compress level This integer parameter specifies the level of text and in-line graphics compression. pdfTEX uses zip compression as provided by zlib. A value of 0 means no compression, 1 means fastest, 9 means best, 2..8 means something in between. Just set this value to 9, unless there is a good reason to do otherwise - 0 is great for testing macros that use \pdfliteral." Best regards, Mats Broberg
