Imports an external image file (PNG) and converts it to authentic 2D retro pixel art with downsampling, palette quantization, and dithering.

Initializes a new in-memory pixel canvas with specified dimensions and palette.

Lists all active canvases and their metadata in the current session.

Returns metadata, dimensions, and palette information for a specific canvas.

Deletes a canvas from memory.

Sets a single pixel at (x, y) with a hex color or palette index.

Efficiently sets multiple pixels at specified coordinates.

Draws a pixel-art rasterized geometric primitive (line, rect, circle).

Fills a contiguous area of matching color starting at (x, y).

Procedurally synthesizes a 2D retro pixel art texture (wood, stone, brick, grass, metal, water) using deterministic algorithms.

Applies ordered Bayer matrix dithering across the canvas.

Generates a 1px pixel-perfect outline around shapes on the canvas.

Exports the pixel canvas to a PNG file, Base64 Data URI, ASCII preview grid, or JSON grid.

Lists all available built-in retro palettes (PICO-8, DB32, Endesga32, GameBoy, NES, Cyberpunk).
