RockBox album cover appearing white'ish

(1/4) > >>

Hello, I recently started using Rockbox, when I noticed, that for some image files, which I have set as album artworks for some songs, appear slightly white'ish or much more grayer than the original image. Like the brightness of that image is messed up or something. Most of the images are ok, just like 10-20% have this defect. Any ideas what could cause this thing?

I also came across this issue. At first I thought there was some bug in display driver, but I took a screendump of a distorted image and it turned out pale on my PC, too. Then I thought the vulnerable images had been encoded by buggy software or with some exotic settings, so I re-encoded them with imagemagick (with the -strip option) and it didn't help. But the funniest thing is that I even took a screenshot of a certain image on my PC (where it looked properly) to eliminate previous encoders' influence. After saving the screenshot and copying it to my player, it was still pale / too bright. It seems as if some colors were not handled properly by Rockbox's image libraries.
I run 3.13 on Sansa Clip Zip.

[Saint]:
It /could/ be a problem with scaling perhaps?

You could test this by making sure the image doesn't need to be resized. You can open the .wps and find the size the theme is expecting, there's be a line along the lines of: %Cl(xpos,ypos,width,height).

I don't know, will try later. However, the images are also affected when viewed in Rockbox's image browser, in any scale.

Just tried, what [Saint] suggested - re-sized images to 96x96 resolution, which is Clip Zip's native one. Surprisingly, for one cover it worked and it appeared as it should. But when I tried to that to some others, they still had the same color defect as before.
