| timofonic | Hello | 16:51.17 |
| ghostbot | Welcome to #ghostscript, the channel for Ghostscript and MuPDF. If you have a question, please ask it, don't ask to ask it. Do be prepared to wait for a reply as devs will check the logs and reply when they come on line. | 16:51.17 |
| Asuran | hi | 16:51.35 |
| ghostbot | Welcome to #ghostscript, the channel for Ghostscript and MuPDF. If you have a question, please ask it, don't ask to ask it. Do be prepared to wait for a reply as devs will check the logs and reply when they come on line. | 16:51.35 |
| Asuran | oh was not my intention to trigger this | 16:51.47 |
| | ^^ | 16:51.48 |
| Robin_Watts | timofonic, Asuran: Hi | 16:51.55 |
| timofonic | What about this? Any plans to update it and make it a table as in mesamatrix? http://twiki.ghostscript.com/do/view/MuPDF/EPubCapabilities | 16:52.11 |
| Asuran | Robin_Watts, i solutioned the problem with fonts i guess | 16:52.12 |
| | if you can remember | 16:52.23 |
| Robin_Watts | timofonic: A wossat? | 16:52.45 |
| | Asuran: You'll have to be more specific, sorry. | 16:53.01 |
| Asuran | no problem i just got it working, nice looking fonts | 16:53.14 |
| timofonic | If MuPDF gets good EPub support, I'm sure many developers would fire Cool Reader 3 Engine :P | 16:53.15 |
| Robin_Watts | timofonic: What's a mesamatrix ? | 16:53.41 |
| Asuran | sounds cool honestly | 16:53.42 |
| | isn't epub mostly html? | 16:53.56 |
| timofonic | There's libmobi, but not sure if would be right to use ut... https://github.com/bfabiszewski/libmobi/ | 16:54.06 |
| | https://mesamatrix.net | 16:54.27 |
| | It parses files to show the features in a pretty way | 16:54.39 |
| Robin_Watts | epub is related to html, yes. | 16:54.41 |
| timofonic | It would be nice to have that for MuPDF | 16:54.53 |
| | MuPDF name is becoming outdated :D | 16:55.10 |
| Robin_Watts | timofonic: We have no plans to do that for MuPDF - too much real work to do :) | 16:55.25 |
| Asuran | if i may interrupt again: are there plans for pdf/a-3u support | 16:56.02 |
| timofonic | Robin_Watts: Just update the EPubCapabilities site a bit, please. I know KOreader developers are very interested on it | 16:56.10 |
| | Asuran: forms? | 16:56.12 |
| Asuran | timofonic, i ask because of attachment support | 16:56.48 |
| | or in general to be honest | 16:56.57 |
| Robin_Watts | Asuran: I have no clue what's involved in pdf/a-3u offhand. | 16:57.32 |
| psmlbhor | Hello, I have generated some PS files containing images with 7 different color models. All are displayed fine except color models adobeRGB 16 bit color depth and sgray with 16 bit depth. Why this would happen ? | 16:57.48 |
| Asuran | im not sure about this psmlbhor but did you specified color profiles? | 16:58.33 |
| | icc profiles to embed | 16:58.39 |
| | you can do this seperate for general, image, text, and idk | 16:58.52 |
| psmlbhor | yes. I did. adobergb 8 bit and sgray 8 bit are working fine | 16:59.09 |
| timofonic | Robin_Watts: I'm not a KOreader ddeveloper, I'm just tired of shitty ebook reader software. I'm just curious about how's the progress on EPub support, KOreader already uses MuPDF https://github.com/koreader/koreader-base/tree/master/thirdparty/mupdf | 17:00.01 |
| Robin_Watts | psmlbhor: Well, the probable answer is that you did it wrong. :) | 17:00.17 |
| timofonic | Robin_Watts: My biggest hope is to surpass cr3 engine at least :D | 17:00.32 |
| Asuran | http://www.ghostscript.com/doc/current/Use.htm# | 17:00.55 |
| | okay then sorry | 17:01.08 |
| Robin_Watts | You'd need to either figure it out yourself, or wait for someone to come along that both understands it enough to help you, and has the time and inclination to do so. | 17:01.17 |
| | I am not a postscript guru, sorry. | 17:01.26 |
| psmlbhor | Robin_Watts, okay. Thanks | 17:01.48 |
| Robin_Watts | timofonic: We have no interest in doing epub-3. | 17:01.48 |
| | but filling in the blanks for epub-2 is on our list. | 17:02.04 |
| | Any help you can offer in doing so would be much appreciated. | 17:02.13 |
| | EPub is not our priority at the moment. | 17:02.38 |
| timofonic | Robin_Watts: I see. I'm not a dev, just a luser. Maybe interested parties would like to provide better EPub support, as CR3 is getting really rusty... | 17:04.13 |
| | Thanks, anyway | 17:04.17 |
| Robin_Watts | We'd like to help, but limited time, etc. | 17:04.43 |
| | Especially given that epub has not been a great seller for us. | 17:05.07 |
| timofonic | Robin_Watts: Why? :( | 17:08.59 |
| Robin_Watts | why what? | 17:09.12 |
| timofonic | not a great seller | 17:09.22 |
| Robin_Watts | The development of mupdf is funded by commercial licensing. | 17:09.37 |
| timofonic | I see very few good EPub readers out there... | 17:09.40 |
| | I see | 17:09.48 |
| Robin_Watts | Yeah, but so far no one has been interested in the epub stuff. | 17:10.07 |
| | (or at least not interested enough to actually put their money where their mouth is) | 17:10.28 |
| timofonic | There's Moon+ Reader Pro, but the developer probably uses it's own code. It seems to be one of the best EPub readers out there | 17:10.56 |
| | http://moondownload.com/ | 17:15.01 |
| | It seems to support EPub3 stuff, yees. The developer is from Hong Kong and this app is sold very well. Anyway, I get it. It's a shame, because MuPDF is fast and renders nicely.. | 17:15.59 |
| | Thanks for all. See you | 17:16.05 |
| Asuran | Robin_Watts, by any chance, are you some kind of expert of pdfwrite? | 18:50.19 |
| Robin_Watts | ghostscript pdfwrite? I am not an expert, but I know something about it. | 18:50.44 |
| Asuran | my problem is still with fonts, i fixed it in one document, font look normal (color) but in my own ones not | 18:51.45 |
| | -dEmbedAllFonts=true ^ | 18:52.04 |
| | -dSubsetFonts=false ^ helped with the first one (ignore the ^) | 18:52.04 |
| | the font is just not as dark as it is in the original pdf | 18:52.46 |
| | like color problems | 18:52.51 |
| Robin_Watts | That would be very unusual. | 18:53.04 |
| Asuran | i guess | 18:53.10 |
| | but it is like that, i even analysed it with paint and saw the font is really lighter in color | 18:53.29 |
| Robin_Watts | What color is the font supposed to be, and in what colorspace? | 18:53.31 |
| Asuran | RGB and black | 18:53.40 |
| Robin_Watts | What is the full command line please? | 18:53.51 |
| Asuran | where can i paste? | 18:54.00 |
| Robin_Watts | pastebin.com | 18:54.10 |
| Asuran | http://pastebin.com/uiyNwtdJ | 18:54.32 |
| | if you remove the 2 lines i posted the one document hasthe problem, with them not... | 18:55.00 |
| | i really dont understand this at all | 18:55.11 |
| Robin_Watts | Well, the fact you're using an ICC profile stands out to me. | 18:55.58 |
| Asuran | i guess its needed for pdf/a | 18:56.19 |
| Robin_Watts | And the NOSUBSTDEVICECOLORS. and the /prepress setings and the the ColorCOnversionStrategy and the RenderIntent. | 18:56.21 |
| Asuran | i added them to try to fix that issue, no use | 18:56.47 |
| Robin_Watts | I think you should pare the options down to the minimum. | 18:56.53 |
| Asuran | i had already | 18:57.00 |
| | thats the problem | 18:57.04 |
| Robin_Watts | and then you might find the options that cause the problem. | 18:57.09 |
| | And if you do, you can talk to kens about them on monday., | 18:57.20 |
| Asuran | it happens with minimum command line as i know | 18:57.21 |
| Robin_Watts | OK, so give me the MINIMUM command line that it goes wrong with. | 18:57.37 |
| Asuran | http://pastebin.com/hvuqkmJ9 | 18:59.54 |
| Robin_Watts | And without the ColorConversionStrategy line it works OK? | 19:00.50 |
| Asuran | no change | 19:02.11 |
| Robin_Watts | Then take that line out. | 19:02.40 |
| Asuran | i did, no change | 19:02.47 |
| | same problem | 19:02.52 |
| | ^^ | 19:02.58 |
| Robin_Watts | keep taking lines out until I have the MINIMUM command line that it does wring. | 19:02.59 |
| Asuran | i posted you this already | 19:03.19 |
| | it was the minimum | 19:03.24 |
| | and now i removed as you sayed colorconversionstrategy | 19:03.37 |
| | still no change | 19:03.40 |
| | and for pdf/a you need to embed profile to be valid | 19:04.04 |
| | its not an option | 19:04.16 |
| Robin_Watts | You posted me a command line that included colorconversionstrategy. Then you told me that if you took it out, it would still go wrong. | 19:05.05 |
| | Thus it was not the minimum. | 19:05.16 |
| Asuran | i took it out after you told me to try so | 19:05.18 |
| Robin_Watts | Right, so are there any other lines you can take out, and it will still go wrong ? | 19:05.39 |
| Asuran | http://pastebin.com/f53YnkZS | 19:06.28 |
| | the minimum i can go to | 19:06.41 |
| | ah it still contains rgb convertion sorry | 19:07.05 |
| | forgot it. | 19:07.07 |
| | just imagine it without it, i tried it like that, exactly like that | 19:07.31 |
| Robin_Watts | OK, so go to bugs.ghostscript.com and open a bug. | 19:09.17 |
| | Add the (correct) minimum command line. | 19:09.33 |
| | Add the smallest example file you can. | 19:09.43 |
| | Explain the problem. | 19:09.48 |
| | Then if you're lucky, kens may look when he returns. | 19:10.09 |
| | The simpler you make it, the more likely it is to be looked at. | 19:10.17 |
