#794 program list icons: image resolution and path
Opened 2 years ago by sobek. Modified 2 years ago

Guideline page needing clarification:



The use case: an image with resolution of 512x512 px is put into the icon folder for images with 128x128 px resolution. Some desktop environments do not handle these misplaced images well, i.e. the icons are displayed multiples times bigger than other images.

As far as I can see there is no information if this is OK or not. I am not a native speaker, maybe that is why. The best information I could find is:

Each directory contains icons designed for a certain nominal icon size and scale, as described by the index.theme file.

from a reference specification that must be followed: https://specifications.freedesktop.org/icon-theme-spec/icon-theme-spec-latest.html#directory_layout

See https://bugzilla.redhat.com/show_bug.cgi?id=1223943 for more details and history about the use case.
See https://bugzilla.redhat.com/show_bug.cgi?id=1624292 for screenshots and the technical solution of Xfce's garcon, which did not handle those misplaced images well, prior to version 0.6.1-21.

A small diversion: I noticed a small typo at: https://pagure.io/packaging-committee
It should be changed to:
tracker is
fixed now

Technically I think that 512x512 icon in 128x128 folder is a bug and I've repeatedly reported such bugs (e.g. in qt5-qtttols).

I wonder whether we actually need guidelines for this. I mean, do we have guidelines that for example explicitly say that a PNG icon must be an actual PNG icon and not a text file that says trollolo?
