This page hosts a formal specification of .bmp file format of Heroes of Might and Magic using Kaitai Struct. This specification can be automatically translated into a variety of programming languages to get a parsing library.


See the usage examples in the JavaScript notes.

Parse structure from an ArrayBuffer:

var arrayBuffer = ...;
var data = new HeroesOfMightAndMagicBmp(new KaitaiStream(arrayBuffer));

After that, one can get various attributes from the structure by accessing fields or properties like:

data.magic // => get magic
