hqx Pixel Art Scaling Algorithm for JavaScript/Canvas

This project is a fork of phoboslab/js-hqx, adding support to Node, through node-canvas.

Live example

CLI Usage

Install hqx:

npm install -g hqx

Run with input + scale ratio:

hqx test.png 2 > test-2x.png
hqx test.png 3 > test-3x.png
hqx test.png 4 > test-4x.png


var scaledCanvas = hqx( originalImage, 3 );

The second argument is the scaling factor. hqx supports 2, 3 and 4. See index.html for an example.
