Thank you..
I solved the problem. Cutting polygon has to be converted to pixel
coordinates. I have missed that point. now it works well ..

Hi,
I can’t really read the code, but based on what happens, maybe your cutline is
outside the image. So you
* create an output band
* fill it with zeroes
* and then you write pixels within the cutline into the output
Because the output stays all zeroes, and there are no errors, then
Thank you ,
I already worked on that code. But clipping was not succesful. output.tif
is blank on qgis.
