How to crop and mask a image at a specific reagion

Hi Folks,

I have to compare two images, but the issue i'm seeing is the image has Date section which keeps on changing. I need to ignore that specific region and then compare to see the results.

Can someone please help me on this ??

If you know where the region is, you can paint over it, making it a constant colour in all the images. For example:

Code: Select all

convert in.png -fill Red -draw "X0,Y0 X1,Y1" out.png
... where X0,Y0 X1,Y1 are opposite corners of the region.
All times are UTC-07:00
