Petrus Posted April 20, 2019 Share Posted April 20, 2019 (edited) Hey! I'm having problem with Hexa colour, when exporting it ! So when I try to export something with the #808080, it usually becomes #7f7f7f. On my test, the #7f7f7f can become something else To check, I'm using the colour picker inside Firefox. I tried with Gimp too, same crazy result ! The goal was to use it as an alpha channel... in Gimp, because it can export it to a game texture .dds DXT5. The only format that can be ok to export the #808080 was on my case .gif Gray. You will be able to find all my files in the .zip file attached, to check the colour exported, and the .afphoto to be sure ! If gray file, I can't make #808080, or a pure 50% black............. Do I need to understand something I don't know ? Thx for your help ! 808080.7z Here are different export from the same file, you can use the browser colour picker if you want Edited April 20, 2019 by Petrus added attached files to show directly Quote Link to comment Share on other sites More sharing options...
walt.farrell Posted April 20, 2019 Share Posted April 20, 2019 I'm not sure I understand what you're saying. But I opened both the RGB .afphoto file and the gray .afphoto file from your attachment, and exported them as JPG files, and opened them in Firefox and in Affinity Photo. In both applications, the application color pickers show the #808080 part of the image as #808080. I also opened your .jpg8.jpg file, and I see the #808080 as #808080, too. If you're not seeing that then I'm not sure what's happening with you.

firstdefence Posted April 20, 2019 Share Posted April 20, 2019 Is the Firefox colour picker set right, I've just tried with Mac colour digital meter and it shows the correct hex numbers for each square. Actually I've just tested your png export and the 808080 reads 7f7f7f and 7f7f7f reads 7f7f7f Quote iMac 27" 2019 Sequoia 15.0 (24A335), iMac 27" Affinity Designer, Photo & Publisher V1 & V2, Adobe, Inkscape, Vectorstyler, Blender, C4D, Sketchup + more...

firstdefence Posted April 20, 2019 Share Posted April 20, 2019 I exported a png24 from the original afphoto file and on my Mac Firefox this reads correctly, a png8 reads as 7f7f7f Quote iMac 27" 2019 Sequoia 15.0 (24A335), iMac 27" Affinity Designer, Photo & Publisher V1 & V2, Adobe, Inkscape, Vectorstyler, Blender, C4D, Sketchup + more...

By the way, remember that the export preset named PNG-24 does not really say anything about the PNG format that is used. Specifically it does not say to produce a png24-format image. It basically just says not to palettize (dither) the output file to limit it to 256 colors, as the PNG-8 export preset does.

Petrus Posted April 21, 2019 Author Share Posted April 21, 2019 Thx all for your answers and tests on your computers ! I'm trying to manage those colours because a game is using this code on an alpha channel for a specific purpose, and I'm trying to hunt the problem that is causing the 0 result on my different tries. So I want just to be sure this is not a possible cause of my problem. And found this little "bug"... I'll go to the game forum to ask if it's a big problem to have this #808080 changing to #7f7f7f... Thx all :) Quote Link to comment Share on other sites More sharing options...
