Image pixelate

POST /api/image-pixelate

Pixelate an image: replace each NxN block with the average colour. Configurable block size. Useful for privacy / redaction and stylisation.

Replaces every `blockSize × blockSize` patch in the image with a single solid colour (the patch's average), producing a mosaic / 8-bit effect. Common uses: - Privacy redaction (faces, license plates, screen content). - Aesthetic stylisation. - Pre-processing for low-resolution downstream displays.
