I have a huge picture with a length of 388800 pixels and a height of 1920 pixels. I want to crop this picture horizontally into multiple small pictures of 1080*1920 pixels.

convert 1-all.png -crop 1080x1920 repage -scene 1 doing1/1-d.png

What I got through the above command is only the first 20 pictures, not all 36 pictures

My original picture is as follows enter link description here

Re-page your input image before you start cropping:
