The library has a wide set of built-in-filters including brightness/contrast, curves, sepia, hue/saturation, noise, lens blur, tilt shift, hexagonal pixelate and much more.
glfx.js has 3 parts:
- texture: a raw source of image data (created from an <img> tag)
- filter: an image effect (represents one or more WebGL shaders)
- canvas: an image buffer that stores the results (a WebGL <canvas> tag)
