| Shreya | +Robin_Watts: Hey, I am trying to implement MuPDF in my android project and I was wondering what the updatePageInternal function is for? I tried reading the documentation and all but i could not find it. Thanks! | 10:01.12 |
| | +Robin_Watts: I am using mupdf 1.2 btw. I tried compiling 1.7a and using it in my project but it kept giving me error saying filr fitz.h could not be found. it gave me the same error for 1.6 and 1.4 version also. | 10:02.27 |
| Robin_Watts | Shreya: That's because you haven't set the include paths up correctly. | 11:12.58 |
| | You need to add the 'include' directory to the include paths for your project. | 11:13.26 |
| | updatePageInternal is the C implementation of updatePage. | 11:14.59 |
| | And that's called by MuPDFPageView.getUpdatePageTask | 11:16.26 |
| Robin_Watts | has just been to the doctors to get tetanus booster after having been bitten by a dog while running yesterday. | 11:17.49 |
| | chrisl: ping | 13:11.22 |
| | I'm writing a device in gs, and including zlib.h, and it's telling me "Cannot include file zlib.h" | 13:11.50 |
| | but other devices are doing so. | 13:11.56 |
| | I'm guessing there is some special makefile sauce I'm missing. | 13:12.07 |
| chrisl | Robin_Watts: erm, give me a sec | 13:16.13 |
| | Robin_Watts: the only device I see that includes zlib.h is gdevfpng.c which is, erm, yours.... | 13:18.31 |
| Robin_Watts | gdevxps.c | 13:18.58 |
| kens | Also gsiorom.c | 13:19.23 |
| chrisl | gsiorom.c isn't a really device | 13:19.42 |
| Robin_Watts | kens: but that's not a device, so might be 'special'. | 13:19.43 |
| kens | Yeah I know, just thought I'd mention it | 13:19.51 |
| chrisl | Robin_Watts: $(II)$(PI_)$(_I) in the compiler flags should do it | 13:21.11 |
| kens | was lookign at that... | 13:21.22 |
| | Maybe _I is enough | 13:21.53 |
| chrisl | No, _I marks the end of an include path (so is normally empty) | 13:22.31 |
| kens | Oh OK | 13:22.37 |
| chrisl | What I don't understand is why we have both 'I_' and 'II' for the beginning of an include path.... | 13:23.17 |
| Robin_Watts | chrisl: Thanks. | 13:23.32 |
| kens | Its hte Ghostscript way | 13:23.33 |
| chrisl | Yeh :-( | 13:24.00 |
| Robin_Watts | WTF is PI_ ? | 13:24.49 |
| chrisl | It's really the include paths for PNG | 13:25.41 |
| | PI_=$(PNGSRCDIR) $(II)$(ZSRCDIR) | 13:25.55 |
| | I'm thinking we should have a 'Z_=$(ZSRCDIR)' | 13:26.29 |
| | But using PI_ should get you going for now | 13:26.43 |
| Robin_Watts | That would feel less arcane. | 13:26.47 |
| | Indeed it does. Thanks! | 13:26.50 |
| chrisl | Robin_Watts: if you pull master, there's a 'ZI_' macro defined that you can use in place of 'PI_' | 14:16.57 |
| Robin_Watts | chrisl: Thanks. | 14:24.02 |
| | mvrhel: Ok, so I have a gproof device for gs now. | 16:36.56 |
| | It produces files that seem plausible. | 16:37.09 |
| | It's essentially a hacked about version of gdevpsd.c | 16:39.44 |
| mvrhel | Robin_Watts: nice! | 16:42.44 |
| | bbiab. moving venues | 16:46.47 |
| Robin_Watts | kens: (For the logs): Warning device first_lastpage implements obselete procedure get_alpha_bits/image_data/end_image | 16:53.48 |
| | And I have pages being displayed. | 17:39.55 |
| | Multicolored pages where the contents are not at all what I would have expected, but... :) | 17:40.13 |
| mvrhel_laptop | Robin_Watts: that is great! I am almost out of my complete tear down and rebuild of gsview. The deep zooming and the screwy scrolling work made me want to completely refactor the code to make it easier | 17:40.56 |
| | Hopefully I can jump in to help you shortly | 17:41.14 |
| | and of course I broke a few things in all this work.. | 17:46.05 |
| | Robin_Watts: so when can I pull what you have? | 17:46.15 |
| Robin_Watts | mvrhel_laptop: Let me bash through the more embarassing mistakes first. | 17:46.51 |
| mvrhel_laptop | How hard to you think it will be to hack away at the android app to 1) include gs library 2) rework the interface | 17:46.52 |
| | Robin_Watts: np | 17:46.58 |
| Robin_Watts | mvrhel_laptop: The android work is the big unknown for me. | 17:47.15 |
| | Including gs in some way should be doable. | 17:47.26 |
| | interface work is the unknown. I may have to call on fred for that. | 17:47.48 |
| mvrhel_laptop | Robin_Watts: ok. I can probably muddle my way through the android ui stuff | 17:47.51 |
| Robin_Watts | ah, cool. | 17:47.58 |
| mvrhel_laptop | or if fred can get it done in short time all the better | 17:48.07 |
| Robin_Watts | But I've got it so that mudraw can generate .gproof files, and mupdf on windows or linux can read them. | 17:48.25 |
| | so we can test it all. | 17:48.34 |
| mvrhel_laptop | cool. I could easily get that up and running in gsview | 17:48.48 |
| | coffee place made a mistake and gave me leaded this morning.... | 17:49.24 |
| | maybe I will get gsview fixed up here today actually at the rate I am typing | 17:49.49 |
| | we were thinking of going camping for a couple days next week, monday and tuesday. after 15 days of 80+ degree weather (tied previous record) and no rain in many weeks it is supposed to rain on monday | 17:51.24 |
| | go figure | 17:51.42 |
| Robin_Watts | mvrhel_laptop: I've seen Greys Anatomy. I know how dangerous seattle can be. Lots of plane crashes, earthquakes etc. | 17:52.21 |
| | mud slides. | 17:52.24 |
| mvrhel_laptop | yes. actually they just had a ice cave collapse north of here | 17:52.41 |
| | several people injured | 17:52.47 |
| Robin_Watts | That's next series. No spoilers! | 17:52.58 |
| mvrhel_laptop | it is the lowest elevation glacier in the lower 48 states | 17:53.10 |
| Robin_Watts | Which one? | 17:53.30 |
| mvrhel_laptop | Near granite falls. Part of mt. baker snoqualmie national forest | 17:53.52 |
| | I had never been there | 17:53.59 |
| Robin_Watts | wonders if I have. | 17:54.03 |
| mvrhel_laptop | but I had heard about it | 17:54.04 |
| | you may have | 17:54.11 |
| | Its in a lot of the tourist books | 17:54.21 |
| Robin_Watts | I'm terrible with names. | 17:54.23 |
| | Columbia! | 17:55.22 |
| mvrhel_laptop | I know they have the facebook app that lets you mark where you have been, but it would be nice to have an app that you can just keep track for yourself and not broadcast where you are or have been | 17:55.23 |
| | there probably is an app | 17:55.34 |
| Robin_Watts | There's no mileage in an app that won't virally share and pull in your friends details for them to advertise to. They are selling eyeballs after all. | 17:56.15 |
| mvrhel_laptop | yes. but I would pay $ for an app that would do what I described above | 17:56.55 |
| | basically a travel app, that lets me store what interesting place I am visiting. maybe with a picture | 17:57.58 |
| | stores the date and time | 17:58.07 |
| | and lets me add other details | 17:58.12 |
| | and does not share it with the entire world | 17:58.21 |
| Robin_Watts | mvrhel: That's a camera with GPS :) | 17:58.23 |
| | and audio notes :) | 17:58.35 |
| mvrhel_laptop | I suppose, but it does not tie it all together | 17:58.47 |
| | with the landmarks etc | 17:58.58 |
| | most people just have a phone | 17:59.23 |
| Robin_Watts | Phones will GPS tag these days. | 17:59.44 |
| mvrhel_laptop | anyway, back to work on gsview | 17:59.44 |
| | yes. but I am thinking more along the lines of the facebook checkin which I like, but I have issues with facebook | 18:00.18 |
| | which is why I am never on there | 18:00.29 |
| | its like I want that part but without facebook | 18:01.05 |
| Robin_Watts | mvrhel_laptop: You want a facebook account with no friends :) | 18:01.07 |
| mvrhel_laptop | hehe | 18:01.10 |
| | oh | 18:01.13 |
| | that reminds me | 18:01.15 |
| | ask siri what 0 divided by 0 is | 18:01.26 |
| Robin_Watts | I would need a siri capable device for that... | 18:01.50 |
| mvrhel_laptop | I guess the mac does not have siri access | 18:02.20 |
| | windows 10 is supposed to have cortona | 18:03.36 |
| | it is funny to ask cortona who siri is | 18:03.44 |
| | now I have forgotten where I was.... | 18:04.59 |
| Robin_Watts | YESS!!!! Proper images. | 18:45.51 |
| | and only moderate heap corruption :) | 18:46.01 |
| | I think I found the heap corruption. | 18:51.44 |
| | So, mvrhel, if you want to play with this stuff... | 18:51.53 |
| | grab the latest gs from robin/master, and build that. That will have a gproof device in it. | 18:52.08 |
| | Then grab the latest mupdf from robin/master, and build that. | 18:52.23 |
| | Then you can do: mudraw -o temp.gproof input.pdf | 18:52.41 |
| | (and that will generate you the index file). | 18:52.49 |
| | Then copy gswin32c.exe and gsdll32.dll into the current directory, and do: | 18:53.10 |
| | mupdf input.pdf | 18:53.16 |
| | I do appear to still have some leaks in mupdf though. | 18:55.12 |
| mvrhel_laptop | Robin_Watts: great. I will get it all this afternoon | 19:12.09 |
| Robin_Watts | I haven't tested it with anything more complex than tiger.eps and pdf_reference17.pdf yet. | 19:13.10 |
| | so the separations stuff should be treated with extreme suspicion. | 19:13.32 |
| | ok, so there are a couple of leaks left. Will look for them on monday, hopefully nothing that should get in your way. | 19:22.41 |
| mvrhel_laptop | thanks Robin_Watts have a great weekend | 19:24.58 |
| | off to lunch.... | 19:25.18 |
| kens | Robin_Watts : you shold only get that warning on a debug build. And I know about t, but I'm going to leave it for now. Because we should eliminate the deprecated methods, and if we haven't (and are still warning) then the device subclassing needs to carry them forward in case someone is still using them | 19:34.11 |
| | I am curious how you are getting the devices loaded though. | 19:34.23 |
| Robin_Watts | by using -dFirstPage and -dLastPage :) | 20:24.00 |
| halabund | Does Ghostscript allow rescaling PDFs without any other modifications? | 20:41.00 |
| | PDFs come with a physical size, e.g. 10 cm. I would like to rescale them without affecting anything else but this size. On-screen they will look the same. However, printing them at 100% will print at a different size. Including them in LaTeX without specifying an explicit size will include at a different size. | 20:42.02 |
| Robin_Watts | halabund: gs is not the tool for that. | 20:47.17 |
| halabund | Robin_Watts: Do you know any tool that can do it? I actually asked about this right here several years ago and I got an answer. But I forgot what it was :( | 20:47.52 |
| Robin_Watts | halabund: I don't know of any tool that can do it trivially. | 20:50.18 |
| | I'd do it by hand hacking the files :) | 20:50.30 |
| halabund | Hm, maybe I can do it with Illustrator. At the moment fortunately I do not need to do this with many PDFs and each is one-page. | 20:52.32 |
| rayjj | halabund: I think gs will do it with: -dDEVICEWIDTHPOINTS=??? -dDEVICEHEIGHTPOINTS=??? -d -dFIXEDMEDIA and using -dFitPage -sDEVICE=pdfwrite -o new.pdf in.pdf | 21:12.51 |
| | he left as I was typing :-( | 21:13.04 |
| | some users have no stamina ;-) | 21:14.00 |
| mvrhel_laptop | whew. I think I finally have the deep zooming and scrolling stuff working and stable | 22:53.40 |
| | I do need to chat with you for a few minutes on Monday Robin_Watts | 22:53.52 |
| | I need to make sure that what I am doing mupdf wise when rendering the tiles makes sense | 22:54.10 |
| | or if there is some performance issue with what i have done | 22:54.22 |
| | more details later | 22:54.25 |
| Robin_Watts | hi | 22:56.19 |
| 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. | 22:56.19 |
| Robin_Watts | you still here? | 22:56.23 |
| mvrhel_laptop | Robin_Watts: I am | 22:57.24 |
| | let me see if I can explain what I did | 22:57.40 |
| | ok. so basically I have a render function that takes a top_left point, a scale factor and the width and height that I want to render to and it adjusts the ctm appropriately , creates the pixmap and runs the display list | 23:03.23 |
| | if you pull gsview from golden and look in muctx.cpp at RenderPageMT it will show you | 23:03.46 |
| | I was just worried that I might be having some penalty or need to supply a bounding box or something | 23:04.05 |
| Robin_Watts | We should be smart enough to calculate the bbox from the pixmap. | 23:04.45 |
| mvrhel_laptop | yes. I had hoped that was the case | 23:04.59 |
| Robin_Watts | I can't see how we wouldn't be (famous last words) | 23:05.20 |
| mvrhel_laptop | but when I make assumptions like that, they bite me sometimes | 23:05.22 |
| | it is pretty fast in release mode | 23:06.01 |
| | debug was a little slow so I was worried but I think I am fine | 23:06.11 |
| | oops I left in some debug stuff | 23:06.29 |
| | ok so zooming is from 1% to 6400% | 23:07.32 |
| | I will build a new installer and do the certification this week | 23:07.45 |
| | weekend | 23:07.54 |
| Robin_Watts | cool. | 23:08.01 |
| mvrhel_laptop | maybe I can work on adding in the proofing stuff.... | 23:09.34 |
| Robin_Watts | I'd better go to bed. gotta get up early (for me) :) | 23:10.06 |
| mvrhel_laptop | ok. have a good night | 23:10.12 |
| Robin_Watts | have a good weekend. | 23:10.17 |
| mvrhel_laptop | you too | 23:10.21 |
| | Forward 1 day (to 2015/07/11)>>> | |
