The process is invertable, such that performing the operation twice produces the original image.
notch filter, noise, clipping, etc.) then demodulate it back into an image (emulating TV hardware functionality) with yet more tweakable parameters.įlips pixel quads to create a subtle blocking effect. The ultimate goal is to build upon this to the point where you can fully transform an image into a broadcast TV frame signal with all sorts of tweakable parameters, apply a number of transmission filters (e.g.
Right now this is a WIP and almost always produces very heavy glitches, but in future it will be significantly more powerful and precise. By shifting the demodulation carrier frequencies, you can gain different failure modes. Supersamples two selected channels of the image, applies a pair of 90-degree phase-shifted carrier waves of a specified frequency, combines the two channels, then performs a demodulation using specified carrier frequencies for each channel. Picks pixels at random and drags them (either horizontally or vertically) based upon a minimum and maximum drag distance.Įmulates a faulty Quadrature Amplitude Modulation system. Shifts pixels up to a certain distance, weighted by the luminance of the pixel.
Essentially a blur that targets detailed areas most heavily. Transforms the image into a digital signal and performs a low-pass filter. Sorts an image's pixels horizontally by value, using Intensity, Hue, Saturation, Luminance, Red, Green, or Blue as the sort key. Simple horizontal interlace effect with optional independent R/G/B channels. This can produce heavy glitch effects or ghost images. Performs a cumulative mathematical operation (add / or / xor) on source pixels given a loop bound amount and step, with an option for horizontal or vertical. Produces interesting effects when affecting only the Y channel, or only the UV channels. No demo image for this - converts between RGB888 and Y'UV444, mapping the channels respectively. Good for generating 3D-like effects that look a bit nicer than linear displacement.Įncrypts the image using AES in Electronic Codebook (ECB) mode, creating a heavy glitch effect that works best with images that have large sections of block colour. R/G/B channel displacement using source pixel intensity as an offset multiplier. I'll demonstrate each filter with the following source image: This library is copyright © 2011 CodeArtEng (Code Art Engineering) and distributed under MIT license. Now bundling the required file with the plugin. The name change is due to a re-architecture of the project namespaces, in line with future features relating to custom file types. IMPORTANT: As of version 1.3, the file name has changed from PolyGlitch.dll to - you will need to delete the old file and copy the new one in.
This DLL is now provided as of version 1.4b, and can be found in the DspToolbox directory of the ZIP archive. PolyGlitch will not work without it, as some of the effects now use various DSP functionality.
IMPORTANT: As of version 1.4, you will now need to download the file (DSP Toolbox, not DSP Lab) and place it in the main Paint.NET directory. They're a bit hacky, but then that's what glitch art is all about This plugin provides a collection of effects designed for glitch art.
