Hi Folks, This isn't really a poppler issue, but I was hoping that someone on the list might have some experience dealing with this edge case.
The PDFs that we process with pdftoppm are regularly sized 42" x 30" and often contain scans of rasterized data. Once in a while, whomever made the scans screws up and puts in 8.5 x 11, even though it's *actually* 42" x 30". Obviously the 150 dpi is far too low and the output quality is horrible. There's a slight chance that the PDFs might actually be 8.5" x 11" so doing a brute force DPI increase might not be a good idea. Does anyone have any good workflows for these sorts of mess-ups? Or is scaling the DPI based on the size difference (544 x 388 -> 3168x2448) the only approach? Here's the pdfinfo dump of the failure: ---- Tagged: no Pages: 1 Encrypted: no Page size: 544.32 x 388.8 pts Page rot: 0 File size: 881061 bytes Optimized: no PDF version: 1.6 ---- Here's a pdf dump of what we expect: ---- Pages: 1 Encrypted: no Page size: 3168 x 2448 pts Page rot: 0 File size: 523131 bytes Optimized: no PDF version: 1.4 ---- I'd be happy to mail anyone the original files if needed (there semi-sensitive, so I didn't want to post them to the list). Thanks for anything :) We *really* enjoy using poppler. -- Ralph _______________________________________________ poppler mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/poppler
