Application icons
Application icons should be installed to $out/share/icons/hicolor
.
Example code for the now outdated scribus v1.4 app:
{ lib
, stdenv
, fetchurl
, imagemagick
}:
let
icon = fetchurl {
url = "https://gist.githubusercontent.com/ejpcmac/a74b762026c9bc4000be624c3d085517/raw/18edc497c5cb6fdeef1c8aede37a0ee68413f9d3/scribus-icon-centered.svg";
sha256 = "0hq3i7c2l50445an9glhhg47kj26y16svfajc6naqn307ph9vzc3";
};
in
stdenv.mkDerivation rec {
pname = "scribus";
nativeBuildInputs = [
imagemagick # convert
];
# ...
postInstall = ''
for i in 16 24 48 64 96 128 256 512; do
mkdir -p $out/share/icons/hicolor/''${i}x''${i}/apps
convert -background none -resize ''${i}x''${i} ${icon} $out/share/icons/hicolor/''${i}x''${i}/apps/${pname}.png
done
'';
}
-background none
will create transparent icons.
Alternative: -background white
.
