Quick install

  1. Download the desired skin from the releases page (see Notes below regarding the sizes), and extract the files form the ZIP.

  2. Copy the extracted .gif and .layout files to the Free42 skin folder.

  3. Select the newly installed skin in the Free42 simulator.

Building from source

  1. Install python pillow dependency:

     pip install pillow

  2. Run the generate.py script with the desired parameters (see Notes below regarding size):

     ./generate.py 3

  3. Copy the generated .gif and .layout files from skins/<NAME>/ to the Free42 skin folder[.

  4. Select the newly installed skin in the Free42 simulator.

Notes

TL;DR: You probably want size 2 or 3 on your Laptop if the size of the simulator is fixed by the size of the skin. On your phone where the simulator adapt to the size of the screen, you probably want the best image quality, go for 12.

The GTK version of Free42 for Linux can not — as far as I know — be scaled manually, that means the size of the GIF defines the size of the simulator on screen. People have personal preferences regarding the on-screen size of their calculator, so I made a script to generate different desired skin sizes.

It is not always possible to use a floating-value display scales (source):

Non-integer display scales are supported in Free42 for Android, iOS, and MacOS, release 2.0.24g and later.

That means the display can only be a multiple of — the original — 131 pixels wide. And if we want the labels on screen to be aligned with the buttons bellow, the skin can only be scaled up and down by integer values as well.

The solution I made is the generate.py scripts that take 3 parameters:

./generate.py [<x_magnification>] [<y_magnification>] [<skin_name>]

The x magnification constrains and defines the final size of the skin. The y magnification can be used to have taller (or smaller) digits on screen, but it does not have impact on the skin size. If omitted if defaults to twice the x magnification. Finally the skin name can be optionally given, allowing you to give meaningful names to your skins.
