Image Resizer

Steps to reproduce

1. Create a new Image Resizer preset within the Settings application of 4000 by 4000 pixels with a Fit setting of "Fit"
2. In Explorer, right-click on any image smaller than 4000 x 4000 pixels
3. Select "Resize with Image Resizer" to open Image Resizer
4. Select the preset created in Step 2
5. Ensure "Make pictures smaller but not larger" is checked
6. Click the Resize button

✔️ Expected Behavior

Either:

1. No work is done because the image already fits within 4000 x 4000 pixels and does not need to be resized, or;
2. The original file is copied, following the filename format and file modified settings defined in the Settings application

❌ Actual Behavior

The image is 'resized' but with the same dimensions as it was originally. For lossy codecs like JPEG, this results in a generational degradation in quality.

Hello and thanks for your message. I think the result is as expected. The app applies a resize action on the image in any case. Just because it's already smaller than the target setting, doesn't make it skip this image or action. At least not currently. So, this would technically be a suggestion for improvement. It means the code will become a little bit more complicated, but the reason is good.

Suggestion for title with this in mind: "Don't touch file(s) if original = result"
