Flipping image coordinates to cartesian coordinates

I am new to mablab. I have an image (the size is mxnx3) with a few human-selected points on the image. For example:

p1 = [267,79];

p2 = [96,372];

These points are image coordinates with (1,1) at the top left. I'm trying to convert this to cartesian coordinates with (0,0) on the bottom left. How can I do this? Thanks in advance!

Try

set(gca,'YDir','reverse')

or

set(gca,'YDir','normal')

until things work the way you want.
