jsfx v0.0.1

jsfx

An image effects library, heavily inspired by https://github.com/evanw/glfx.js. I needed something that could fallback to a canvas, and additionally, I needed the same effects to render server side.

This library is currently in heavy development, and not tested. You should probably refrain from using it in production until it becomes stable.

todo

• Need to move jsfx.Filter and jsfx.FilterInterface into the jsfx.filter namespace, but the compilation doesn't work as the single output file is not ordered (BrightnessContrast gets defined before the interface or base class)
• Get feedback on usage of Typescript (the way files are separated, lack of Uint8TypedArray in UnsharpMask, etc).
• Figure out how to have certain static variables per WebGL Rendering context. I am currently casting to any, and assigning a variable. (vertexBuffer and texCoordBuffer in Shader, frameBuffer in Texture, and shaderCache in Renderer)
• Add more filters
• A lot of the filter files have the comments and the webgl shaders copied from glfx.js. I should probably attribute the single files as well as mentioning it in the credits.
• Add tests
• Test server side rendering with node-canvas, and add documentation
• Add minified build

future

• Currently, only the Canvas filters take advantage of IterableFilter. Perhaps implement something similar for WebGL whereby shaders for a combination of filters are generated, and applied once. This is not very important as these filters are fairly light weight, and the WebGL implementation is already considered much faster (relative to Canvas).
