Application Features

Version 2.0
V2 introduces enhanced speed, new features, and a refined interface:

• ⚡ Highly Optimized: Instant results for most images, even at larger sizes.
• Auto-Refresh Toggle: See changes live as you tweak the settings.
• Dithering Options: Choose between Floyd-Steinberg,2x2 Bayer, 4x4 Bayer, Ordered,Clustered 4x4 and atkinson, and adjust dithering strength in real-time.
• ? Palette Support: Use default palettes from Lospec or import custom ones via Lospec's API using a palette slug (e.g., rgbg-36 from Lospec Palette).
• ? Custom Palette Management: Create custom palettes, save them to local cache, or download and upload them in JSON format.
• ? Resolution Control: Download your pixelated image at the input image’s resolution or as actual pixel art.
• ? Auto-Detect Image Size: Easily set the pixel width to match the original image size (great for spritesheets).

Using the API

You can use the image-to-pixel library in your own projects. Pass an image and options to the pixelate function, and get a beautifully dithered image in return.
Note: The API is still a work in progress; official documentation is under development.

Example Usage

Add the library to your project:

Use via CDN;

<script src="https://cdn.jsdelivr.net/gh/Tezumie/Image-to-Pixel@main/image-to-pixel.js"></script>

Or use locally (Recommended);

<script src="image-to-pixel.js"></script>

JavaScript Example

ditheredCanvas = await pixelate({
  image: myCanvas,             // Accepts HTML canvas, image elements, or q5/p5.js image objects
  width: 128,                  // Set pixelation width
  dither: 'Floyd-Steinberg',   // Dithering method ('Floyd-Steinberg', 'Ordered','2x2 Bayer', '4x4 Bayer',`Clustered 4x4` or `atkinson`)
  strength: 20,                // Dithering strength (0-100)
  //palette: 'rgbg-36',        // Optional: Lospec palette slug (depends on Lospec API availability)
  //Recommended: Define a custom palette //  // You can also set `palette: null,` to use the colors from your original image //
  palette: [ 
    '#1b1b1e', '#f4f1de', '#e07a5f',
    '#3d405b', '#81b29a', '#f2cc8f',
    '#8d5a97', '#ef3054'
  ],
  resolution: 'original'       // Use 'original' for full resolution, or 'pixel' for pixelated size
});

You can also set it up with p5/q5 through p5.prototype.registerMethod.

Try a Demo Using image-to-pixel API with p5play here.

let myCanvas; // add a reference for the input canvas 

function setup() {
	myCanvas = createCanvas(windowWidth, windowHeight);
}
...
...
async function draw() {
}

//-----------------------Function to pixelate entire sketch-----------------------//
p5.prototype.registerMethod('post', async function pixelateAndRender() {
	ditheredCanvas = await pixelate({
		image: myCanvas,
		width: 320,
		dither: 'ordered',
		strength: 11,
		palette: [
			'#1b1b1e', '#f4f1de', '#e07a5f',
			'#3d405b', '#495c92', '#596da7', '#81b29a', '#f2cc8f',
			'#8d5a97', '#ef3054', '#d3d0be', '#4a7762', '#364e43',
		],
		resolution: 'pixelated'
	});
	image(ditheredCanvas, 0, 0, width, height);
});
