ArtChanger

Paper plugin mapping internet images into item frames with auto aspect-based grids, high-quality dithering+sharpen, persistence across restarts, anti-dup drops, multi-source URLs, rotation, EN/RU locales, safe and fast by bdiev_.

Key Features:

- Load images from URLs (Instagram, Discord CDN, Telegram, Imgur, ImgBB, any direct link) - Auto grid sizing by aspect ratio (e.g., 1:1 → 3x3, 16:9 → 4x2, 4:3 → 4x3; manual 3x2 / 5x5 also supported) - Rectangular grids with placement validation and chunk-load restoration (tile metadata stored) - High-quality pipeline: multi-step downscale, sharpening, Floyd–Steinberg dithering, palette mapping to Minecraft maps - Rotate with right-click; delete with left-click (clears group, keeps main frame) - Anti-dup: auto-created frames do not drop; only one frame drops per grid - Persistence across restarts (image ID + grid metadata stored in frames) - Asynchronous downloads (non-blocking for the server)

Commands:

- /artchanger set <url> [size] - size formats: 3 (square), 3x2 (rectangular). If omitted → auto-sized by aspect ratio. - /artchanger help — show help

Usage:

- Shift + Right click to paste item in the frame - Run /artchanger set <url> [size] - Right-click an item frame to place the image - Right-click again to rotate - Left-click to remove the picture (main frame stays; grid auto-frames are removed without drops)

Grid Sizing:

- Auto: aspect-ratio based (1:1→3x3, 16:9→4x2, 4:3→4x3, 3:2→3x2, 2:3→2x3, 9:16→2x4, panorama>2.5→5x2) - Manual: /artchanger set <url> 4x3 or /artchanger set <url> 5 - Max recommended grid: 10x10
