How to cut many images by coordinates?

Question

bash

I wonder how to automate the process of cutting many .tif images from one .tif image, if there are coordinates of the upper left corner of each of these images in a format, for example, excel or simply listed in a text document.
I'm going to use ImageMagick's convert -crop, and the question arises, how can I pass a lot of coordinates there instead of entering them manually?
All cut out images are the same size, square.

Answer 1

Write a bash script that will read your text document and call imageMagic:

IFS=','
while read i val; do
  вызов imageMagic $i, $val #$i - первый размер $val - второй размер
done < input.txt

the values ​​of the coordinates of the corners must be in the lines of the input.txt file, separated by commas:

0,100
100,200

Answer 2

Obviously write a small script. On bash it is most likely possible to do this, but I would use Python.
He always helps me out where bash can't.
You can use both the PIL library and call convert for each image.
