In this project we've developed a converter that converts .bmp to .karol and then do the same, yet in the opposite direction. By default, Byte Run is performed. The conversion is accompanied by additional operations. First one is converting to Grayscale, to Imposed Color Palette or to Color Palette chosen by Median Cut algorithm. Those last two choices yield in return an image that has 64-color palette. After that, user is prompted to decide whether to use Floyd-Steinberg (a.k.a dithering) algorithm or not. Last option consists of choices for what to do with the output - save it as .bmp, .karol or not to save it at all.

In order to launch the converter make sure you have properly intialised SDL with Visual Studio 2017.
