Re: [NTG-pdftex] Creating identical PDF files with different pdfTeX runs

Comparing bitmaps, as some people already suggested, is a good thing.

It shouldn't be too difficult to write a script which produces a bitmap file for each page (using ghostscript) and then creates a file which consists of lines like

<pagenumber> <md5sum of the bitmap file>

The bitmap files can be removed by the script when it is finished and standard UNIX tools can be used to examine the output files.

Particularly, diff(1) can be used efficiently. It will tell you the numbers of the pages which are different.

That's a very good suggestion, thanks! Regards, Frank -- Frank Küster Single Molecule Spectroscopy, Protein Folding @ Inst. f. Biochemie, Univ. Zürich Debian Developer (teTeX)
