cmapbash

A Minecraft map renderer written in C.

Uses the following libraries:

• cNBT - https://github.com/FliPPeh/cNBT
• LodePNG - http://lodev.org/lodepng

Supports orthographic and isometric rendering.

Options so far:

• -i - Isometric mode.
• -d - Dark mode.
• -s - Render sunlight shadows in isometric mode.
• -b - Render biome colours.
• -t - Tiny mode. Renders a quick minimap of all existing chunks.
• -n - Render nether dimension. Overrides -e.
• -e - Render end dimension.
• -w <directory> - The path to the Minecraft world folder (required).
• -o <filename> - The path at which to save a single image. Defaults to map.png, unless -g is specified, in which case defaults to none.
• -g <directory> - The directory in which to save a set of tiles, suitable for use with Google Maps. This will create subfolders for a number of zoom levels, depending on the map's size.
• -r <#> - Rotate the map # x 90 degrees clockwise. By default, north is at the top in orthographic mode, and northwest is at the top in isometric mode.
• -F <Y> -T <Y> - Render only the vertical slice from one height to the other.
• -F <X>,<Z> -T <X>,<Z> - Render only the rectangular area from one corner to the other.
• -F <X>,<Y>,<Z> -T <X>,<Y>,<Z> - Render only the cuboid from one set of coordinates to the other.

This happens to be my first C project.
