Where should icons for desktop files be stored? Some packages use
/usr/share/pixmaps. Others use subdirectories under
/usr/share/pixmaps (some directories are unowned too). Some use a
private directory under /usr/share/<name>. Still others use
/usr/share/icons/.
Icon=/usr/share/sane/xsane/xsane-logo.xpm
rpm -ql gnome-utils | grep /usr/share/pixmaps
/usr/share/pixmaps/gsearchtool/thumbnail_frame.png
file /usr/share/pixmaps/gsearchtool is not owned by any package
How should the icon be referred to in a desktop file? Some use
absolute paths, others no path at all. desktop-file-install complains
if there is a relative or partial path.
Icon=/usr/share/system-config-lvm/pixmaps/lv_icon.png
Icon=/usr/share/system-config-selinux/system-config-selinux.png
Some desktop file icons don't use an extention, but some do:
Icon=accessories-calculator
Icon=accessories-dictionary.png
It looks like the majority of the desktop files on my F9 system are
using the form without an extension.
All of this is confusing. For new applications, what should they use?
What are the semantics for the various syntaxes that are used? What
should be done for upstream packages that have icons? What if they
are in xpm format rather than png?
Thanks.
