Glitch

Description

A simple program to apply common datamosh effects to images. This repo includes both the command line utility and a (horrible) GUI.

Requirements

• ImageMagick (http://www.imagemagick.org) version >= 7.0

Capabilities

The current supported functions are as follows

• Shifting random rows of pixels (uses data from the previous row to fill-in missing data on the end)
• RGB shift/Chromatic aberration, shift can be directed and scalled as desired.
• Dual image XOR/AND/OR/NOTXOR combinations.
• Also includes general data mosh/corruption effects founded on manipulating the byte/bit data of the pixels of the image.

Examples

A row shift effect:

A RGB shift (Chromatic aberration):

Of course these effects can be combined for interesting results.

RGB shift with the row shift effect:

or even all three effects applied together:

Plans and ideas:

• Optimizations, this project what created very early into my college career and so there is plenty of room for improvement.
• Unit tests.
• .gif support.
• The ability to set a number of iterations and have each one either exported to a folder or a .gif.
• More effects!
  • More general curruption of the image.
  • JPEG artifacting. Need to review the JPEG standard and possibly create a custom format manipulator.
• Finish the GUI.
• A GIMP plugin.
