Generate .iconset and relative .icns directly from the Terminal

Generate .iconset and .icns files

This is a small shell script that allows you to create .iconset and .icns files. For the .iconset file, the script will generate 16x16, 32x32, 64x64, 128x128, 256x256, 512x512 and 1024x1024 px images. This can be modified in the generate_icns.py file's size array.

Prerequisites

• Python 3.x
• cv2 (which can be downloaded from the Terminal using the following command: pip3 install opencv-python)

How to use it

1. Place the file mkicon.sh in /usr/local/bin and remove its extension (this can be done by using the command: mv ./mkicon.sh /usr/local/bin/mkicon);
2. Place the file generate_icns.py in the home directory (this can be done by using the command: mv ./generate_icns.py ~);
3. Logout of your machine in order to save the changes;
4. Now you can use the command mkicon [-i | -h] image destination wherever you are
