JPEGlitch test suite

Well, it's been a while, but I finally got an improved test suite together for my JPEG glitching experiments.

The code available here includes the previously released JPEGlitch and JPEGlitch for HYPE, as well as the source for the 'decode glitching', where the JPEG bytes are mangled to add glitches before being loaded.

The interface allows you to control various glitch parameters and you can either process continuously or one step at a time. Each module has a pre-made set of parameters - choose 'example' in the snapshots drop-down of a module window to select them. You can also load /save JPEG images to your local file-system.

The UI might have some minor bugs, but it's usable. I've modified the lovely minimalcomps UI component set from bit-101, adding a custom framework for easy creation of parameter based interfaces. I also added bitmap icons to minimalcomps - compiling the 1000 famfamfam silk icons into a handy SWC - with all icons pre-compiled into buttons for importing into the project. Read more about creating the icon library, read the set-up guide, and get the code to do it separately, here.

This update is a step on the way to a larger suite of byte-glitching tools for images, audio, video, text, or any other file you might want to mess with... no eta. on that, but it's in the brain pipes.

JPEGlitch update…

Just a quick update on some new features and improvements to my JPEG glitching code for AS3.

Check out a little demo of newly added 'decode glitching' here and see some test images saved from the Flash, here.

It should work with most JPEGs -  I've implemented and tested parsing for progressive/baseline/optimised etc. But if you find one that won't load, let me know and I'll see if I can add support for it.

This is still a work in progress, so all the user control of glitching and the source code will come at a later date.

Enjoy.

JPEGlitch

glitchGrab5

I've been experimenting with glitched JPEG encoding in Flash and have created a version of Thibault Imbert's optimised JPEG encoder that gives control over various glitch parameters.

JPEGlitch Example

A simple test suite that lets you control parameters, experiment with the JPEGlitch class, and load/save images locally. This example uses the minimalcomps ui component library from bit-101.

JPEGlitchRhythm for HYPE

I also made a rhythm for the HYPE framework using the JPEGlitch encoder.

This example is an audio visualiser based on a HYPE sound analyser example and plays 2 short tunes endlessly. The rhythm encodes and re-encodes a bitmap, adding the freshly rendered oscillator canvas on top each time.

This is also my entry to the HYPE 'Friday 13th' competition.

Feed your code-eyes :)

Update 14/01/10 - JPEGlitch get's an honorable mention in the HYPE competition :)
