| Zeroneca | Hey, love this pdf viewer! One (or two) question(s): Is it possible to change the background color of mupdf? I would like to change from this gray to black or even better to transparency. Do I need to touch the source for that or does some sort of extension for this exist? | 14:23.11 |
| | oh I forgot to mention I'm on linux, so I'm talking about the linux (OpenGL) viewer | 14:24.49 |
| | If this is the wrong place to ask just say so :) | 14:36.42 |
| pink_mist | this is the right place, but the people who work on mupdf are usually mostly around during european business hours | 14:41.58 |
| Zeroneca | So sunday is just a bad day to ask? | 14:52.33 |
| | Do I need to ask my question again at a better suited time or do some people also respond to messages in the log? | 14:53.47 |
| pink_mist | they should respond to the log | 14:54.40 |
| Zeroneca | ok cool thank you ping_mist ! | 14:54.53 |
| | *pink (how could this typo happen lol) | 14:56.15 |
| ator | Zeroneca: changing the background color is easy, if you edit the one line in the source and recompile :) | 16:03.41 |
| | Zeroneca: inverted mode changes to a black background too, IIRC | 16:03.52 |
| | in platform/gl/gl-main.c, in the function run_main_loop, the calls to glClearColor set the background color | 16:04.26 |
| Zeroneca | ator: nice, thank you! I guess transparency isn't supported? | 16:04.47 |
| ator | no, transparent windows aren't a thing in X11 (the ones that do, use really ugly hacks that do a screengrab without the window and then draw on top of that) | 16:05.39 |
| | but don't forget the shrinkwrap mode, to shrink the window to fit the page | 16:06.02 |
| pink_mist | if you're using a compositor, transparency would be properly supported ... but I have no idea about how people actually write programs for that | 16:07.02 |
| Zeroneca | I know about that, but that does not work as expected, but maybe that's something specific to i3 | 16:07.14 |
| pink_mist | I meant that to ator | 16:08.00 |
| Zeroneca | I do, but using the compositor to make the window transparent would not only make the background transparent but also the slides (which I don't want to be) | 16:08.06 |
| | pink_mist: sorry I replied to ator. I should reply with the username more often | 16:08.56 |
| pink_mist | so should I :P | 16:09.02 |
| Zeroneca | ator: So the window doesn't always actually fit the slide when hitting w even if my screen is big enough | 16:10.39 |
| pink_mist | Zeroneca: wait, I just picked up on the fact you're using i3? doesn't that mean nothing will be behind since it's a tiling wm? :P | 16:12.03 |
| Zeroneca | pink_mist: yeah sure, but I'm of course only hitting w when toggling floating mode for that window | 16:12.42 |
| | ator: wait, what is the 4th argument to glClearColor for? Isn't that the alpha value? | 16:13.44 |
| pink_mist | oh right, it does have a floating mode | 16:13.46 |
| | Zeroneca: yeah, if that's the alpha value it would make sense that's how you support transparency with a compositor | 16:15.18 |
| | (not that I know whether it is the alpha value or not) | 16:15.32 |
| Zeroneca | I just did a quick ddg and it seems to be. I'm quickly trying it out (thanks to gentoo patching is super easy) and reporting the result afterwards here :) | 16:16.17 |
| | Okay, changing the color succeeded but the alpha value doesn't seem to change anything | 16:22.08 |
| | anyways, thanks for your help! | 16:35.18 |
| avih | ator: orthogonal to the utf8 patch (i have more changes, but i'm waiting for any response first), here's a patch which removes string interning of String object value https://0x0.st/ic_a.txt . need to know your preferences on the TODO items, then i can clean it up of them | 17:50.11 |
| mendel_munkis | Is it possible to hide a layer in mupdf? | 22:32.44 |
| Robin_Watts | mendel_munkis: Using the library, or mutool, yes. If you're using mutool draw to render, look at the -y option. | 23:42.32 |
| | If you're using one of the example viewers, then no, not currently. | 23:42.46 |
