Hi I talked about this at the foss4g 2 years ago and shared a bash script where I do exactly what you are asking for. I don't know if you consider it to be easy, but the example is this script: https://gist.github.com/LarsSchy/9ecb31eb964dd83820c139b2f2769a7c (https://gist.github.com/LarsSchy/9ecb31eb964dd83820c139b2f2769a7c)
Look at the function: retile_with_mask() in the script. The script is doing other things as well like creating a tile index for Mapserver usage and trimming the tiles from nodata parts. Have fun / Lars S. 11 november 2021 kl. 15:46, "Lorenzo Di Giacomo" <[email protected] (mailto:[email protected]?to=%22Lorenzo%20Di%20Giacomo%22%20<[email protected]>)> skrev: Hi, i can't find a simple way (not to choose the cut coordinates manually) in order to crop an entire raster image into N images given a fixed size of pixel, how can this be achieved? Thanks
