AutoPalette (Client-Side)

Tired of sitting at an easel for hours, clicking pixel-by-pixel with dyes, just to paint a custom image in Minecraft?

AutoPalette is a lightweight, client-side Fabric mod for Minecraft 1.21.8 that automates painting custom images on server-side ArtMap (or DFArt) easels. Simply select your image, check the automatically generated shopping list of dyes, sit down, and let the mod paint for you!

Features

• Intuitive In-Game GUI: Press H (customizable) to open a control dashboard inside the game. Browse local images, tweak settings, and watch your image preview change in real-time.
• Quantization and Dithering: Choose between direct nearest-color matching or high-fidelity Floyd-Steinberg dithering to make pictures look incredibly crisp on the map.
• Max Colors Palette Limiter: Restrict your image's palette to the top Unlimited, 32, 16, or 8 most frequent colors. The GUI preview re-renders instantly to reflect your choice.
• In-Game Shopping List: The Materials tab calculates exactly how many dyes, coal, and feathers you need. It even renders live 16x16 Minecraft item icons next to each entry.
• Smart Pixel Skipping: The mod reads the canvas state before drawing and automatically skips painting any pixels that already match your image, saving you massive amounts of dye and drawing time.
• Coal and Charcoal Interchangeability: The mod intelligently treats coal and charcoal interchangeably for shading and base black steps, utilizing whatever is available in your inventory.
• Pixel-Perfect Alignment: Utilizes pre-serialized lookups (east.ser, west.ser, etc.) and a vanilla MapColor database (mappings.json) to guarantee 100% boundary alignment and color accuracy on the canvas.

How to Use

1. Import Images: Put your image files (PNG or JPG) into the .minecraft/config/autopalette/images/ directory.
2. Open the GUI: Sit on an ArtMap easel with a canvas, and press H to open the panel.
3. Set Up: Select your image, toggle dithering, set your drawing delay, and choose your color limit.

1. Collect Dyes: Click the Materials tab to check your shopping list, and gather the required items in your inventory.

1. Draw: Click Start Drawing! The mod will automatically swap tools/dyes into your hotbar, turn your camera, and paint the canvas.
