Hi,

Please add gdalinfo of the source image. Even better if you can share the image.

Aihe: [gdal-dev] oblique cuts on a raster using python GDAL

Hi ,

I have problems with oblique cuts on a raster using python GDAL (3.6.2)

- with this line i obtain black borders around :
gdal.warp('raster-dst' , raster-src', cutLineDSName='geometry-extraction.shp', cropToCutline=True)

- with this one, the crop is not clean on closer inspection: residual black pixels around image and white pixels appear in the image.
gdal. warp( 'raster-dst' , raster-src', cutLineDSName='geometry-extraction.shp', cropToCutline=True, copyMetaData=True, dstNodata=0)

I tried, without success, to refine with outputBounds=[minX, maxX, minY, maxY], under QGIS directly ….
I've run out of ideas :/
A (naive) question comes to mind: Is it possible to make oblique cuts with gdal.warp() & co?
