| | ?? | 12:39.45 |
| kundan | HELP | 12:50.11 |
| kens | Stop shouting | 12:50.19 |
| kundan | oops | 12:50.51 |
| kens | If you have a question ask it, nobody is going to reply to you shouting help | 12:50.52 |
| kundan | I want to add signature over pdf with mupdf. | 12:52.07 |
| | but i am very stuck | 12:52.22 |
| kens | And what, exactly, do you mean by 'signtature' ? | 12:52.31 |
| kundan | i mean digital image over pdf | 12:53.10 |
| kens | A bitmap image ? | 12:53.17 |
| kundan | yes | 12:53.23 |
| kens | You'll have to wait for one fo the MuPDF developers to have some time then, I don't know enough to help you. | 12:53.48 |
| kundan | okey Thanks | 12:54.21 |
| ipecac | hello | 13:41.16 |
| mubot | Welcome to #mupdf, the channel for 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. | 13:41.16 |
| ipecac | I am using mupdf 1.12.0-2, and while viewing one pdf file, there is this warning poping in my terminal: "warning: assert: overwrite hash slot with different value!" | 13:50.20 |
| kens | Hmm, I thought that was a debug only message | 13:50.38 |
| | I also thought it was harmless, just a warning | 13:50.51 |
| | I'm afraid you'll need to wait until someone better informed than me is available though, sorry. | 13:51.13 |
| ipecac | This happens only with one specific pdf file, and it happens only when i "scroll back". This message do not appear when i am going through the file unsing 'j' or scrolling, but just when i go up | 13:52.03 |
| kens | I'm fairly sure someone mentioned something similar over the last couple of days, you could look back through the IRC logs to see if it helps | 13:52.47 |
| ipecac | Okay, thanks | 13:53.33 |
| Kundan | Help | 13:58.09 |
| kens | Kundan : you're going to have to wait. | 13:58.30 |
| | The channel is logged and someone will reply when they have spare time | 13:58.44 |
| | I notice you have also opened a Stack Overflow question. You should add the detail I asked you for earlier. You need to make it plain you want to add a bitmap image to an existing PDF file. Your qeustion is ambiguous since it could refer to digitally signing a PDF file, adding an annotation, or adding an image. | 13:59.49 |
| ipecac | Someone reported a similar issue the february 05, except the application does not crash (yet) in my case | 14:06.15 |
| | Should I also send the incriminated file to someone? | 14:07.02 |
| sebras | ipecac: yes, please attach it to a bug report over at bugs.ghostscript.com | 14:17.14 |
| | ipecac: I don't think we have yet found out where the previously reported issue stems from. | 14:17.33 |
| | ipecac: also describe exactly what you need to do inte mupdf viewer to reproduce the issue. and whether you are using mupdf-x11 or mupdf-gl (it doesn't sound like you are using mupdf on android or ios) | 14:18.27 |
| ipecac | I am using the mupdf package present on the "community" repository of the ArchLinux distribution | 14:20.51 |
| Kundan | currently i am usring mupdf-x11 | 14:21.08 |
| sebras | ipecac: that's fine, just describe the issue as detailed as possible. we might ask you for further information via e-mail later if we are having a hard time reproducing the issue. | 14:23.02 |
| tor8 | Kundan: there is no pdf editing capabilities in mupdf-x11 | 14:24.44 |
| | you'll need to either write a tool using the mupdf library, or a script using 'mutool run' | 14:25.02 |
| | doing either will be difficult without a good understanding of the PDF format | 14:25.33 |
| ipecac | sebras: Okay, I'll do that | 14:26.28 |
| sebras | ipecac: excellent, thank you. | 14:26.36 |
| Kundan | tor8 can you please suggest me any tutorial or other resources which helped me | 14:26.37 |
| tor8 | I suggest you study the PDF reference first, then you can look at the documentation and examples on https://mupdf.com/docs/manual-mutool-run.html | 14:27.38 |
| | If you want to add an image to an existing page, you will need to add an image resource to the PDF document, and add some graphics drawing commands to the page content stream that will draw the image | 14:28.23 |
| | you can find the pdf reference on adobe's website. if you want easier reading, you can read version 1.3 (it's ancient, but it covers all the basics without getting bogged down in fancy new features) | 14:29.26 |
| | version 1.7 is the last version released by Adobe | 14:29.55 |
| sebras | Kundan: your stack overflow question is tagged android and jni. do you want to do this for an android app or for the mupdf-x11 destkop viewer? | 14:30.10 |
| Kundan | sebras i want this for android app | 14:31.24 |
| tor8 | Kundan: then why did you say "i am using mupdf-x11"? | 14:31.47 |
| Kundan | sorry it was my fault | 14:32.17 |
| sebras | Kundan: so this is an app where a user can add an image as a signature and then then use that to digitally sign a PDF document? | 14:32.19 |
| Kundan | yes | 14:32.49 |
| sebras | Kundan: what license will the android app be released under? | 14:32.50 |
| Kundan | yes sir i will | 14:33.49 |
| | but currently i am stuck to implement it | 14:34.24 |
| sebras | Kundan: I'm not sure I understand your answer. what license will the app be released under? | 14:35.26 |
| Robin_Watts | Kundan: MuPDF is released under 2 licenses. The first one, is the GNU AGPL. If you use this license, then you can use MuPDF for free. This means that your app will have to be released under the GNU AGPL too. That means all the source for the entire app has to be made public. Are you prepared to do that? | 14:36.20 |
| | If not, then either you'll need to take a commercial license for the app (which will you cost you money), or you can't use MuPDF at all. | 14:36.51 |
| Kundan | i have not more knowledge about that but i am using this for public not commercial | 14:37.49 |
| Robin_Watts | I don't understand what you mean by that. | 14:38.48 |
| | Either you will undertake to abide by all the terms and conditions of the GNU AGPL, or you won't. | 14:39.15 |
| sebras | Kundan: the licensing must be followed regardless of thi is commercial or public use. | 14:39.22 |
| Kundan | i will do MuPDF is released under 2 licenses | 14:40.11 |
| sebras | Kundan: ok. under what two licenses? | 14:41.04 |
| Kundan | sorry for GNU AGPL this licence | 14:41.40 |
| | can you please solve my problem | 14:41.55 |
| Robin_Watts | Kundan: The GNU AGPL comes with no guarantee of support or warranty. | 14:44.00 |
| | We try to help people out where we can, but our priority has to be on paying customers. | 14:44.40 |
| | The clearer, and more specific you can be in a) what you are trying to do, and b) exactly what your problem is, the more chance you have of getting help. | 14:45.13 |
| | i.e. if we have to guess what you're doing, and what you're trying to do, and what you've tried... we'll probably just go back to the work we have to do. | 14:46.04 |
| tor8 | Kundan: I can't solve your problem because you still haven't told us what it is. | 14:46.15 |
| | If your problem is "please do my homework for me" then the answer is "no, we can't do that". | 14:46.29 |
| Kundan | I want to add digital bitmap in the place of signature over pdf with Mupdf but i am very stuck with above issue please | 14:47.04 |
| | i think now you understand verrey | 14:47.34 |
| tor8 | that sounds an awful lot like "do my homework". | 14:47.37 |
| Kundan | well | 14:47.39 |
| tor8 | what is a digital bitmap, and "in the place of signature" could mean just about anything. | 14:47.57 |
| Kundan | forget about digital | 14:48.23 |
| | i want to just add a bitmap | 14:48.31 |
| | over pdf | 14:48.38 |
| tor8 | I told you how to do that 20 minutes ago. | 14:49.05 |
| | "If you want to add an image to an existing page, you will need to add an image resource to the PDF document, and add some graphics drawing commands to the page content stream that will draw the image" | 14:49.42 |
| Kundan | can you please suggest me some link or other resources | 14:51.08 |
| kens | tor8 did that too | 14:51.27 |
| Kundan | okey | 14:51.46 |
| | Thanks for your time | 14:54.22 |
| sebras | titanous: several oss-fuzz issues have been automagically closed but I haven't yet looked into whether the claimed fix is indeed the valid fix for the issue or whether it just prevents the issue from manifesting itself. | 15:27.39 |
| | titanous: when I have looked into them I'll add comments as I have done previously. | 15:27.59 |
| ipecac | hello again | 20:17.11 |
| | I tried to report the bug I described earlier, however when i try to send the form on bugs.ghostscript.com, the page freeze, and I get a 500 Internal Server Error few minutes after | 20:21.32 |
