Yes it should be changed to PPI. The pdftocairo manpage and --help text uses PPI. ___ poppler mailing list poppler@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/poppler

Probably the manpage and --help text are inaccurate and should say PPI instead of DPI, since pdftoppm is outputting to an image and not a printer. ___ poppler mailing list poppler@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/poppler
[poppler] Question about setting PPI when generating image from pdftoppm
Hi All, I'm trying to set PPI when generating image from pdftoppm,but it seems like we only have parameters to set DPI "-r". I think the "r" here means resolution and the value should be a DPI. Since DPI is different from PPI, what if I want to set resolution by using PPI? Is there a way to translate them or there's another parameter which can take PPI? Thanks, Min ___ poppler mailing list poppler@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/poppler
