Feature request #21251

Set output file resolution option and CRS options to Processing Clip Raster to Mask Layer - ClipRasterByMask.py

Pull Request or Patch supplied:Yes Resolution:fixed/implemented
Easy fix?:No Copied to github as #:29069


This is a feature request to add the output file resolution option to Clip Raster to Mask Layer. This was possible in QGIS 2.18 Raster -> Extraction -> Clipper, but not in the Processing implementation of gdalwarp.

I also propose the introduction of -s_srs and -t_srs options, to overcome this issue, that will only be fixed in GDAL 2.4.1:



I'm making a proposal patch, but please make a review, because it is fully functional, but the code can be not too polite.

The only problem I see is, as they are QgsProcessingParameterBoolean (and not radio buttons), a user can check both KEEP_RESOLUTION and SET_RESOLUTION at the same time. Is there any form to put them mutually exclusive in Processing? If not, I think a user needs to know what is doing when activate an option that is, by default, unselected.

Thank you very much!

works fine here (tested on Windows only), are you comfortable submitting a pull request on Github?

#2 Updated by Pedro Venâncio almost 2 years ago

This version of the patch adds the -multi option, already added to master by Giovanni.

This way should work in master and 3.4.4 without problems.

  • Resolution set to fixed/implemented
  • Status changed from Open to Closed

The patch was merged into 3.6 and master, while for 3.4 was closed is not really a bug fix.

Anyway here https://github.com/qgis/QGIS/pull/9445 a few comments were made, and possibly this could lead to tweak the already committed patches to 3.6 and master.
