Readme.md

#Rgb2Hires This program coverts an RGB image to the Apple II's "HiRes" format. Provided it complies with its constraints:

  • Source image must be 140x280. Pixels are anamorphic: twice wider than tall.
  • Source image must contains six colors : BLACK, WHITE, ORANGE, GREEN, BLUE and PURPLE

For more information about the "Hires" format and its limitations, please refer to Wikipedia: https://en.wikipedia.org/wiki/Apple_II_graphics#High-Resolution_.28Hi-Res.29_graphics

Compiling

Rgb2Hires

The source is provided as a Visual Studio project. It's standard C++11 without any Windows dependency so it should compile on Linux and macOs without any modification.

Dependencies

  • Magick++ : On Windows, you have provide an environment variable called MAGICK_HOME and pointing to the ImageMagick folder.

Loader (for Apple II)

This program will compile as an Apple II executable that you can run on the actual hardware.

Dependencies

  • CC65: Please provide an environment variable, CC65_HOME, pointing to your CC65 folder.

Running

A correct source image, test.png, is provided as an example. Convert it into a file named test.picture as the Apple II Loader will try to load and display a file called like that.
