I have a close functionality in Mirone but it was developed mainly for
grids, though it works also with images.
With a grid/image loaded, load the polygon too. Next right-click on the
polygon line and select
ROI Crop Tools -> Crop Image (or any of the other related options)
and it's done. One thing you may not like is that the resulting image is
not of the same size (extent) as the original. This is so because I
(don't remember anymore why) decided to save only the extent
corresponding to the BoundingBox of the polygon.

Hi
I have exacly the same problem. It is resampling to the extent of the
polygon instead of croping just the pixels inside the polygon and
using the pixel frame of the original image. How can this be fixed?

Greetings
I have a raster image and a shapefile polygon and I wanted to crop the
raster for just to have valid pixels inside the polygon. I have used
crop_to_cutline but here is a problem:
It produces a raster map but pixels does not geographically match with
the original raster map. So, i produce a raster map but I'm not able to
compare with original image since there is a small displacement. How can
I obtain a raster map without this mismatch?
Thank you
Regards,
Antonio
