Processing + JPGs
After meeting Ted Davis (FFD8) and attending his panel with Paul Hertz at Gli.tc/h in Chicago earlier this month, I decided that I should get over my personal aversion to programming.
Using Processing, I’ve written a primitive (and probably poorly structured) program that will enable me to go through a file byte by byte and sequentially change the value of a particular byte.
The GIF above started as a JPG. By stepping byte number 0xC4 (or the 196th byte in the file) through values 128 through 220, the alignment of the image raster was thrown askew.
Writing a program to proceduralize the restructuring of data doesn’t seem antithetical to the glitch ethos. Though, somehow there’s a line that is crossed once that code becomes packaged and sold, used only for a particular effect, rather than extended further. At that point, the process seems little different from the ritualized produce/consume (prosume) paradigm established by large “productivity” software firms. For me, anyways, glitch has been about skirting the usual channels of productivity. Creating your own tools is part of that.
