Released under GNU AGPL 3.0

A library for converting images to Commodore 64 bitmap formats. Supports both multicolor (160x200, 4 colors per cell) and hires (320x200, 2 colors per cell) bitmap modes with Floyd-Steinberg dithering and brightness bias controls.

Features

  • MulticolorConverter - Converts images to C64 multicolor bitmap format (160x200 pixels, 4 colors per 8x8 character cell)
  • HiresConverter - Converts images to C64 standard (hires) bitmap format (320x200 pixels, 2 colors per 8x8 character cell)
  • C64MulticolorData - Container for multicolor bitmap data (8KB bitmap, 1KB color RAM, 1KB screen RAM)
  • C64HiresData - Container for hires bitmap data (8KB bitmap, 1KB screen RAM)
  • C64Palette - C64 16-color palette with accurate RGB values and closest-color matching

Dependencies

  • Magick.NET (ImageMagick) - Image processing

Usage

using ImageMagick;
using Casasoft.Commodore;
using Casasoft.Commodore.Images;

// Load an image and convert to multicolor format
using var image = new MagickImage("input.png");
var converter = new MulticolorConverter();
var result = converter.ConvertImage(image, useDithering: true, brightnessBias: 0.35);

// Access the resulting data
byte[] bitmapData = result.BitmapData;  // 8KB
byte[] colorRam = result.ColorRam;      // 1KB
byte[] screenRam = result.ScreenRam;    // 1KB
byte bgColor = result.BackgroundColor;  // Background color (VIC-II $D021)
