PNGlitch

Build Status

PNGlitch is a Ruby library to destroy your PNG images.

With normal data-bending technique, a glitch against PNG will easily fail because of the checksum function. We provide a fail-proof destruction for it. Using this library you will see beautiful and various PNG artifacts.

For more details about glitching PNG image, see my documentation The Art of PNG Glitch.

Usage

  require 'pnglitch'

  PNGlitch.open('/path/to/your/image.png') do |p|
    p.glitch do |data|
      data.gsub /\d/, 'x'
    end
    p.save '/path/to/broken/image.png'
  end

The Art of PNG Glitch includes the usage of this library.
