This is only needed for Companion (for testing purposes).
As soon as @Taifun has adjusted his extension (TaifunFile) accordingly, this is no longer needed:

How to make not to CROP but just scale to fit screen...like this

Taifun · October 28, 2021, 5:39pm

read the documentation of the Scale method from the image extension App Inventor Extensions: Image | Pura Vida Apps
there are also other methods available...

Scale a jpg image file in the ASD - application specific directory.
The parameter scalingLogic expects the value FIT or CROP. CROP keeps the aspect ratio, resulting either in the width or the height of the source image being cropped.
