Citacop

Aka. Convert Image to Amiga Color Palette (and then Save as IFF ILBM)
By Arda 'ref' Erdikmen

A simple tool to do the actual work.
Citacop is written for OCS Systems. Deluxe Paint, Personal Paint, Amos, and other OCS/ESC image viewers will love your exported image files. :D
Citacop exports highly compatible, uncompressed raw ILBM.

Supports Amiga Low-Res, Med-Res and Laced saving. Aspect ratio compansation when previewing Med-res images. 2 to 32 Colors are supported. EHB and HAM modes are NOT supported.

Features

• 🖼️ Color Quantization: Reduce the color depth of images to a specified number of colors.
• 🎨 Amigafy an Image: Generate Amiga palettes and apply them to your image to constrain colors to 4096 Amiga colors (this is not Amiga-compatible, of course—it’s for an authentic Amiga 500 look).
• ✨ Advanced Dithering: Apply ordered dithering (Bayer matrix), Floyd-Steinberg dithering, or no dithering (dithering is kind of crap, but it’s what I want actually 😄).
• 📏 Flexible Image Resizing and Cropping: Resize or crop images dynamically with aspect ratio locking.
• 🔄 Undo/Redo States: Save and revert to previous states for non-destructive editing.
• 🖌️ Palette Visualization: Preview reduced palettes in a dedicated floating window.
• 💾 Export Options: Save images in multiple formats, including BMP, JPG, PNG, and Amiga IFF (ILBM).

V1.1: Added functions:

• Load/Save palette files of Deluxe Paint 4 (SET), Personal Paint (PAL, COL), ILBM CMAP chunks (IFF), Adobe Color Table (ACT)
• Can edit palette
• Lock a palette and apply to any image
• 64color EHB is now supported. (Still no HAM though)
• New Dithering Modes
