image-to-ascii is a Node.js module that converts raster images into character-based terminal artwork. Input can come from a local file, remote URL, or in-memory Buffer. The converter maps pixel brightness to a configurable sequence of ASCII characters. It can preserve the original colors through ANSI foreground or background styles or generate plain monochrome output. Options control width, height, screen fitting, aspect ratio, transparency, reversed brightness, and custom background colors. Developers can receive a final string or work with the underlying pixel matrix through custom processing functions. ...

...The library is structured around three components: textures (image sources), filters (shader pipelines), and canvases (render targets), making it easy to compose multiple effects. A demo page showcases a variety of filters, from basic brightness/contrast adjustments to more advanced distortions and color manipulations. glfx.js remains a handy reference and solution for anyone needing client-side photo editing, visual effects, or generative graphics powered by WebGL.
