1371969 - Images without embedded color profile render incorrectly

Status: RESOLVED DUPLICATE of bug 455077

(Core :: Graphics: ImageLib, defect, P3)

Description

[u596779]

User Agent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/59.0.3071.86 Safari/537.36

Steps to reproduce:

Open any local or web-hosted color image not tagged with a color profile.


I use MozillaFirefox-52.1.1-57.9.1.x86_64 on openSUSE Leap 42.2

I am also using oyranos with correctly selected monitor profile. My monitor is wide-gamut and calibrated properly. In gwenview and RawTherapee I see colors correctly for all untagged images.

The test shows the same result in the latest stable Windows version.


Actual results:

The untagged images are oversaturated (incorrectly color managed)


Expected results:

The untagged images should appear as if tagged with sRGB profile.

If you go to about:config and change gfx.color_management.mode from 2 to 1, it will solve the problem for you (note that already decoded images will be wrong, restart to be sure). Many years ago it was determined it was too costly to enable all the time, although I do wonder if that is still true today. Something to investigate. I note that Chrome 59 has the same behaviour as us, untagged is not adjusted for sRGB, from what I could tell at http://cameratico.com/tools/web-browser-color-management-test/.

I know that about:config workaround but it is not a fix. 99.9999% of people won't do it and will keep seeing wrong color.

But how come in Windows it is ok but in Linux it is too costly? I hope you can fix this.

I know and I have reported that one too.
