Changing aspect ratio - Ruprecht - 09-01-2020
I have an image with an aspect ratio of 0.62:1 and I want to change it to 0.71:1 and live with the distortion: the image includes text so it can't be cropped.
As a new user, I have spent what seems like hours Googling "changing aspect ratio with Gimp" and trying without success the few answers I found.
Can anyone please walk me through a method or point me to a tutorial? I use Windows 10 and Gimp 2.10.20.

Ruprecht: What happens if you scale the image (Image => Scale Image), changing only the height or width, and with the Height and Width values unlinked (broken chain icon). Does that give you the effect you want?
Cheers. . .

Do not want to crop, so need to scale down width by a multiplier ?
I make that 0.62 / 0.71 = 0.8732 (87.32 %)
Use Image -> Scale Image and in the dialogue break the link between Width and Height.
Gimp can do the arithmetic for you (*0.62/0.71) screenshot https://i.imgur.com/qHnJg2G.jpg
or
Change the units to percentage and enter
Note: Gimp works in pixels so there are often rounding up/down adjustments with image pixel size.
