My request : I want to Liquid Rescale just a part of an image.
The param "-liquid-rescale" seems it only applies to the whole image.
Can anyone tell me any other solutions?
Thanks for any hint

There was talk of improving the Liquid rescale but I do not think it happened as the developers are very busy.
Maybe a bit of lateral thinking; crop the part of the image you want to rescale and then composite or append it back onto the original?

Have you tried -region?
Alternately, crop the section you want, process with liquid-rescale and then composite the result back. Or create a mask for the region you want, use liquid rescale on the whole image, then use the mask to composite between the original and rescaled result.

Yes, I've tried this, but the effect is not good.
Sometimes there will be a gap on the image after compositing.
