Hi, This is not really a bug, but it makes it effectively impossible to compare two PDFs, at least from a script. Here is a typical context diff, from 07-08-c3/widgets/xfdf-001.pdf.diff: *** 147,164 **** endobj 16 0 obj << ! /BaseFont /Times-Roman /Subtype /Type1 ! /Name /rmtf /Type /Font /Encoding 14 0 R >> endobj 17 0 obj << ! /BaseFont /Courier /Subtype /Type1 ! /Name /tttf /Type /Font /Encoding 14 0 R >> --- 147,164 ---- endobj 16 0 obj << ! /BaseFont /Courier /Subtype /Type1 ! /Name /tttf /Type /Font /Encoding 14 0 R >> endobj 17 0 obj << ! /BaseFont /Times-Roman /Subtype /Type1 ! /Name /rmtf /Type /Font /Encoding 14 0 R >> /Lars
