SYNOPSIS
ppmshift shift [file]
DESCRIPTION
ppmshift randomly shifts each row of a PPM image horizontally by a random amount up to the specified maximum. This creates a glitch-like distortion effect where the image appears to have horizontal tearing or displacement.
A random seed option allows reproducible results. The effect is similar to analog video signal interference or digital glitch art. Part of the Netpbm toolkit.
