[07:13] <grogbot> [discord] <scemino> If someone wants to help me on this, he's welcome
[07:43] <grogbot> [discord] <_lman_> But isnt the game screen set to 1280x720? Or is it due to the textures being clamped? If the latter case w we could change the textures to next power of two to also get OpenGL ES support
[08:27] <grogbot> [discord] <scemino> Yes the game screen is set to 1280x720

[13:13] <grogbot> [discord] <paolo86cripple> Hi, non-crt shaders are behaving quite weirdly for me . Cannot have a clue as to why. Here's a screenshot of a golden wake running with 6xbrz-linear . Using Arch linux with 3070 on it.

[14:23] <grogbot> [discord] <lephilousophe> you should check with retroarch how it behaves

[17:06] <grogbot> [discord] <scemino> I don't see any difference between scummvm and the original (except the color brightness).

[17:40] <Scummette> scummvm/master e16cc61 scemino: TWP: Add missing final on BreakWhileCond
[17:49] <grogbot> [discord] <eientei> Not an issue, it's just that if you look closely at the game, each "pixel" of the screen is 3px but it has an extra 1px on each side to make it 1280px wide, so if you ignore the extra 2px, it doesn't downscale neatly. Again, just a me problem and not an issue with the engine at all
[17:49] <grogbot> [discord] <eientei> *if you don't remove the extra 2px
[18:11] <Scummette> [scummvm] AndywinXp pushed 1 new commits to master: https://is.gd/xJnZE2
[18:11] <Scummette> scummvm/master 56ae4e9 AndywinXp: SCUMM: DIG: Fix #15067
[18:35] <grogbot> [discord] <scemino> That's because of this, I suppose, the height of the bridge "room" is 172, so the virtual screen size is 428x240:
[18:35] <grogbot> [discord] <scemino> ```c++
[18:35] <grogbot> [discord] <scemino> Math::Vector2d Room::getScreenSize() {
[18:35] <grogbot> [discord] <scemino> switch (_height) {
[18:35] <grogbot> [discord] <scemino> case 128:
[18:35] <grogbot> [discord] <scemino> return {320, 180};
[18:35] <grogbot> [discord] <scemino> case 172:
[18:35] <grogbot> [discord] <scemino> return {428, 240};
[18:35] <grogbot> [discord] <scemino> case 256:
[18:35] <grogbot> [discord] <scemino> return {640, 360};
[18:35] <grogbot> [discord] <scemino> default:
[18:35] <grogbot> [discord] <scemino> return {_roomSize.getX(), (float)_height};
[18:35] <grogbot> [discord] <scemino> }
[18:35] <grogbot> [discord] <scemino> }
[18:35] <grogbot> [discord] <scemino> ```
[18:37] <grogbot> [discord] <codengine_de> When I look at those pictures the colors seem to be slightly different
[18:37] <grogbot> [discord] <scemino> Yes, I agree
[18:37] <grogbot> [discord] <codengine_de> Thats especially noticable in the sky
[18:37] L555BAT (L555BAT@user/L555BAT) left #scummvm (WeeChat 4.2.2).
[18:37] --> James|GlideM joined #scummvm.
[18:37] <James|GlideM> Evening folks
[18:38] <grogbot> [discord] <codengine_de> The right one is a bit more saturated
[18:39] <James|GlideM> Havent used IRC in a long time, but now using it on my Amiga A500 is even more strange :)
[18:49] <grogbot> [discord] <scemino> Maybe if I tweak the room shader parameters I can find the correct style (not in this screenshot for sure 😉 , it was just an example)
[18:49] <grogbot> [discord] <scemino> https://cdn.discordapp.com/attachments/581224061091446795/1229141488684896346/Screenshot_2024-04-14_at_20.47.34.png?ex=662e9a37&is=661c2537&hm=131af5b2b84cb0918f377689b0ed7962c326f65195be2391c3e855e875a19101&
[18:52] <grogbot> [discord] <codengine_de> In direct comparison, I also noticed at the bridge that while scrolling, in the original version the graphics are much more "stable"?
[18:52] <grogbot> [discord] <codengine_de> In the ScummVM version the straight lines are somehow jagged... hard to explain what I mean.
[18:55] <grogbot> [discord] <codengine_de> Here is a diff-ed image (ignore the verbs) but I think something is a teenie tiny bit off
[18:55] <grogbot> [discord] <codengine_de> https://cdn.discordapp.com/attachments/581224061091446795/1229143006863556770/grafik.png?ex=662e9ba1&is=661c26a1&hm=882fec4c44a7aec3f55a68040518c3f8704026190e09088ea9e7b02859dce23f&
[18:55] <grogbot> [discord] <codengine_de> (also ignore the moving parts :D)
[19:00] <grogbot> [discord] <codengine_de> Here is another Diff where everything is mostly still:
[19:00] <grogbot> [discord] <codengine_de> https://cdn.discordapp.com/attachments/581224061091446795/1229144159219093574/grafik.png?ex=662e9cb3&is=661c27b3&hm=4932b3cbd886afdcabfed52e22638608fa4f6ac0bd786f7aa4d5c070177c2876&
[19:01] <grogbot> [discord] <scemino> Interesting
[19:01] <grogbot> [discord] <scemino> I never thought of doing an image comparison, that's a good idea
[19:03] <grogbot> [discord] <codengine_de> but overall, for a very first release, the result is already impressive 👍

[19:04] <Scummette> scummvm/master 595d708 sluicebox: SCI: Add Betrayed Alliance Book 2 Demo detection and workarounds
[19:05] <grogbot> [discord] <scemino> By doing image comparison, do you think we can find the right parameters for the colors?
[19:06] <grogbot> [discord] <scemino> I know nothing about image stuff.
[19:11] <grogbot> [discord] <codengine_de> Hm I don't know how to do a scientifically correct calculation of the parameters 😄
[19:14] <grogbot> [discord] <codengine_de> Well, there is a way, by brute forcing you could change the numbers in a loop, sample the colors of some pixels and compare where its closest to the original 😛
[19:16] <grogbot> [discord] <scemino> I change the parameters by hand, I can be close to the final result but is it enough?
[19:16] <grogbot> [discord] <scemino> If I change the parameters by hand, I can be close to the final result but is it enough? (edited)
[19:21] <-- James|GlideM left irc: Read error: Connection reset by peer
[19:21] <grogbot> [discord] <codengine_de> I guess its enough if its close enough to the original, I also only saw it in a direct comparison
[19:22] <grogbot> [discord] <codengine_de> maybe its more noticable in colorful scenes, like the circus
[19:22] <grogbot> [discord] <codengine_de> in some scenes its much less of an issue
