Image to h3m (v0.0.0)| Convert images into maps for Heroes 3

This tool allows you to convert images into terrain in downloadable, editable h3m files for Heroes of Might and Magic 3. Use the settings in the sidebar to map the image's color clusters to terrain types and more. (Note: Map outputs are in Horn of the Abyss format by default. Disable HotA in the sidebar for Shadow of Death compatibility.)
