First off, check if Preview.png already exists. If so, don't bother with the rest of this.
Regex this part in the Index.ini file to get the path to the IconFile:
IconFile = ContentFile\n<whitespace>Path = (.*)\n
Note: IconFiles can be any size, they don't even have to be rectangular!
Get the color of the top-left pixel in the image and use that color to fill the left and right sides.
Assuming you have a 23x23 px one, it could be scaled by a factor of 9 in the width and height to get a 207x207 image.
By then making the canvas the width of the image * 16 / 9, the new width of the canvas becomes 368x207. This is a perfect 16:9 ratio, which is what mod.io recommends.
Now fill in the left and right sides with the color gotten before and save the image as Preview.png to the converted mod's folder.
