CamoJack is a browser based tool for creating and editing camouflage patterns. It runs entirely in plain JavaScript with no framework behind it, and works as both a pattern generator and a tile editor, meaning you can create a pattern algorithmically and then paint over or adjust it by hand. For generating patterns, the tool includes fourteen different algorithms, covering styles like organic voronoi shapes, cloud like noise textures, digital pixel style patterns similar to military MARPAT, blotches, tiger stripes, brushstroke style patterns, and more geometric options like honeycomb and carbon fiber weaves. On top of these algorithms sit more than twenty five ready made presets, recreating recognizable looks such as woodland, multicam, desert, flecktarn, and kryptek, alongside playful novelty options like a volcano or zombie themed pattern. Color choices come from over thirty curated palettes grouped into military, biome, and novelty categories, and you can also pull a palette directly out of an uploaded image using a color clustering technique. Once a pattern exists, the built in tile editor lets you refine it with a full set of painting tools, including a brush, eraser, smear tool, clone stamp, spray tools, shape tools for lines, rectangles and gradients, flood fill, and an eyedropper for picking colors off the canvas. Brushes wrap around the edges of the tile and the software automatically smooths the seams, so the result can repeat without visible edges when tiled. There is also a stamp library for generating or importing small blob shapes that can be rotated, resized, and randomized, plus a feature for blending two separately generated patterns together. Standard editing conveniences like undo, redo, and detection of duplicate work are included as well. When finished, you can export a single tile or a repeated sheet made of up to an eight by eight grid of tiles. The project runs locally after installing its dependencies and starting a development server, and it can also be built into a standalone output folder. CamoJack is released under the MIT license.
