DIFFIMG(1)                  General Commands Manual                  DIFFIMG(1)

NAME
       diffimg - Calculates intersection between two images

SYNOPSIS
       diffimg image1 image2 [outimage]

DESCRIPTION
       diffimg  generates  an  image where each pixel is the difference between
       the corresponding pixel in each of the two source images.  Thus, if  the
       source  images are the same the resulting image will be black, otherwise
       it will have regions of non‐black where the images differ.

       Currently supports: .png, .gif, .jpg, and .ps by using ghostscript

Title: diffimg - Calculates Intersection Between Two Images
Summary
The `diffimg` command calculates the pixel-by-pixel difference between two images and generates a new image representing this difference. Identical images will result in a black image, while differences will be shown as non-black regions. It supports common image formats like .png, .gif, .jpg, and .ps.
