Bug in pdf/pdftables.w
by Lars Hamren 12 Sep '16

Hi, Those who enjoy such things can try to find the bug in this code, which happes to have for quite some time: int pdf_create_obj(PDF pdf, int t, int i) { int a; char *ss = NULL; if (pdf->obj_ptr == sup_obj_tab_size) overflow("indirect objects table size", (unsigned) pdf->obj_tab_size); if (pdf->obj_ptr == pdf->obj_tab_size) { a = pdf->obj_tab_size / 5; if (pdf->obj_tab_size < sup_obj_tab_size - a) pdf->obj_tab_size = pdf->obj_tab_size + a; else pdf->obj_tab_size = sup_obj_tab_size; pdf->obj_tab = xreallocarray(pdf->obj_tab, obj_entry, (unsigned) pdf->obj_tab_size); } pdf->obj_ptr++; obj_info(pdf, pdf->obj_ptr) = i; obj_type(pdf, pdf->obj_ptr) = t; It is both simple and potentially fatal. Answer in my next post. /Lars ------------------------------------------------------------------- Lars Hamrén WWW...: www.sdu.se Vadmöllan 211 Mobile: +46(705)189090 S-225 94 Lund Sweden

/Basefont written in varying order to PDF file
by Lars Hamren 06 Sep '16

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

Varying behaviour for ligatures
by Lars Hamren 05 Sep '16

05 Sep '16

Hi, Sometimes some ligatures are recognised, sometimes not. Here is part of the diff for two runs of attributes/boxes-001.pdf.diff *** 4485,4491 **** <0071> <0057> <0072> <0077> <0076> <0079> ! <007A> <00660066> <011B> <2014> endbfchar endcmap --- 4485,4491 ---- <0071> <0057> <0072> <0077> <0076> <0079> ! <007A> <FB00> <011B> <2014> endbfchar endcmap There are also some very small differences on coordinates, but I guess that they are the results of different widths. This happens for 283 out of the 324 .tex files. /Lars
