What I tried My first attempt was to play around with the offset values for -crop to set the focus point of the image: convert photo.jpg -resize 1440x560 -crop '1440x560+25+25' result. Got 353 and 356 in dimension 3 at /opt/conda/conda-bld/pytorch-nightly_1540496378087/work/aten/src/TH/generic/THTensorMoreMath. ImageMagick Command-line Options Annotated List of Command-line Options Below is list of command-line options recognized by the ImageMagick command-line tools. 4 Answers Sorted by: 61 Assuming that you always know the size of your image you can do it like this: convert original.jpg -crop 640圆20+0+0 cropped.jpg With the -crop operator you specify the size of the cut out image and the offset from the upper left corner of the old image. As you can see, the crop has its center point where the focus point on the original image is. RuntimeError: invalid argument 0: Sizes of tensors must match except in dimension 0.
