Hello readers and followers,

Today we are going to learn how to build an icns icon file.

First:

Let’s create an iconset folder:

Now, let’s use a code script to work on, it’s a gist that I found:

mkdir icon.iconset

output_path=~/Projects/ringsce/icon.iconset

# the convert command comes from imagemagick
for size in 16 32 64 128 256; do
half=”$(($size / 2))”
convert RINGSCE_V2.png -resize x$size $output_path/icon_${size}x${size}.png
convert RINGSCE_V2.png -resize x$size $output_path/icon_${half}x${half}@2x.png
done

iconutil -c icns $output_path

Now, we are going to run this script. We are going to improve that.
