Description Thomas Groman 2021-03-09 22:25:51 UTC
media-libs/libpng-1.6.37-r2 does not display images encoded with a Rec. 2020 PQ colorspace (High Dynamic Range) correctly, instead making the image incredibly dark and hard to view. This effects all dependent software, including libQt5
Comment 1 Sam James archtester Gentoo Infrastructure gentoo-dev Security 2021-03-09 22:29:07 UTC
Compared to what?

* -r2 fixed a broken symlink over -r1
* -r1 just bumped EAPI

Could you give some more information please? And emerge --info?

How about the rest? :)

I'm not sure exactly what your asking for. Do you want a side by side comparison of the raw source image in the editor, srgb encoded image in view, and rec. 2020 PQ encoded image in a viewer?

"Compared to what?

* -r2 fixed a broken symlink over -r1
* -r1 just bumped EAPI"

So, 1.6.37-r2 is broken. But what worked?

Oh, I'm not aware of any previous version that worked correctly. I just noticed some contacts in my XMPP roster had very dark icons, then a few weeks later I made some art in Krita and curiously enabled the 'Rec. 2020 PQ' option in PNG export, and noticed the same exact over-darkness happened to the exported png and this did not happen when that option was left disabled.

I contacted the developer in the XMPP client and they said it just uses what libQt5 uses for png support, which a quick ldd on libQt5.so reported that was libpng
