Generate and install png icons from svg file

genicons.sh

#!/usr/bin/bash

src=$1
dst=${1%.*}.png

[[ -z "$2" ]] && type="apps" || type=$2

for i in 16 22 24 32 64 128
do
  inkscape -z -e $dst -w $i -h $i $src
  xdg-icon-resource install --context $type --size $i $dst
  rm $dst
done

In case someone stumbles upon this gist there seems to be a couple changes since this was posted 7 years ago:

The Inkscape flag changes, -e is now -o and -z doesn't appear to exist or be needed any longer.

xgd-icon-resource needed a --novendor flag to process names that didn't meet a particular naming convention, due to a vendor prefix now being required. I updated the prefix in the name, however and skipped the flag.

I converted it to a function and added it to my .zshrc and made a couple changes to suit my needs.

function genicons() {
  src=$1

  [[ -z "$2" ]] && type="apps" || type=$2

  for size in 16 22 24 32 48 64 128 256 512 1024
  do
    output=${1%.*}-icon_$size.png
    inkscape -o $output -w $size -h $size $src
    xdg-icon-resource install --context $type --size $size $output
    echo "Added icon ~/.local/share/icons/hicolor/${size}x${size}/apps/${output}"
    rm $output
  done
}

why no 48x48?

why no 48x48?

You can add any size you want to the for loop. I updated it to include 48x48 for you, but add any more you think you'd need.

These are all the ones that currently exist on my machine:
