Nintendo pixelation
The example converts a static image into a stylized NES-style pixelation by averaging colors in blocks of pixels and mapping them to the closest NES palette color in LAB color space. It processes the image in shuffled batches, updating the canvas progressively to show the transformation over time. The code uses D3 for selection and shuffling, Canvas `getImageData` and `putImageData` for pixel manipulation, and the `requestAnimationFrame` loop to animate the batch processing. The source image is loaded from "magritte.jpg," and the palette comes from the included `nes-palette.js`.
AI-generated descriptionConvert image to a somewhat NES-style image:
- Get the colors of each square of n pixels.
- Convert those colors from RGB to LAB and average them.
- Round that color to the closest color in the NES palette.
- Convert back to RGB and set all n pixels to that color.
