| kens | ator, sebras, Robin_Watts_ there's a question in comp.lang.postscript about MuPDF this morning. I'm happy to post an answer (assuming nobody else has easy access to UseNet newsgroups) but I don't know what to say, here's the question:: | 07:28.28 |
| | I'm only getting started investing how to turn a PDF into EPUB. | 07:28.46 |
| | By default*, "mutool draw" saves pictures within the HTML files as base64, and breaks paragraphs into indepdent lines with <p>…</p>. | 07:28.46 |
| | mutool draw -F html -o out.%d.html in.pdf | 07:28.46 |
| | I was wondering if there were a way to… | 07:28.51 |
| | 1. Have it keep paragraphs together | 07:28.51 |
| | 2. Save pictures as external JPG/PNG files instead of including them in the HTML f | 07:28.51 |
| | Its the business of saving the images as external files and (presumably) linking to them I don;'t know about | 07:30.30 |
| sebras | kens: saving images extnally to the html isn't something mupdf does today. | 07:41.26 |
| kens | sebras, thanks (sorry internet died) I'll write up a reply on UseNet | 07:58.26 |
| sebras | kens: I don't know if epub support is something ator has ever considered. | 08:03.59 |
| kens | As an outptu formt ? No idea :-) | 08:04.17 |
| sebras | yeah. nope, me neither. | 08:04.26 |
| kens | Just explaining in my reply why there are no paragraphs in a PDF file | 08:04.58 |
| paulgardiner | I think we may be encrypting the digest within the value of a signed signature. It's relatively harmless in that we do this only when trying to write out the initial, all-zero form which we later overwrite most of, but it means we now can see seemingly random data after the true digest. | 08:18.16 |
| | Presumably we aren't decrypting when we read the content from the value, otherwise the signatures wouldn't verify | 08:45.31 |
| pedr0 | hi all, I came across a very puzzling outcome while dealing with a PDF - apparently the rendering mode is set to '3' - namely invisible - yet the text appears on the page | 16:14.16 |
| | https://pastebin.com/sPcncSpL | 16:14.16 |
| | Would anybody in here be able to point me into the right direction ? I suspect that the 'ri' operation may affect somehow the rendering but the PDF reference wasn't very clear, at least at my level, about what that entails. | 16:15.52 |
| sebras | pedr0: do you mind waiting until monday when most of us mupdf devs are back after the weekend? | 16:18.11 |
| pedr0 | Guys - I am basically asking you a favor soaking in your knowledge. Not need to ask, reply when you can or feel about that | 16:19.31 |
| | Thanks for now :-) | 16:19.53 |
| sebras | pedr0: to make sure no one forgets you can register a bug at bugs.ghostscript.com and attach the PDF (let me know if you want me to mark it private so only you and us devs see it). | 16:25.30 |
| pedr0 | I don't want to open a bug as I am afraid the problem lies in my poor understanding of the matter - I will re-post the question here on Monday :-) | 16:33.51 |
| sebras | pedr0: alright, thanks for the patience. :) | 16:35.47 |
