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.


Runtime library

All parsing code for Java generated by Kaitai Struct depends on the Java runtime library. You have to install it before you can parse data.

The Java runtime library is published in the Maven Central Repository. Refer to the artifact page for instructions how to add it into your project with the build tool that you use.


Parse a local file and get structure in memory:

HeroesOfMightAndMagicBmp data = HeroesOfMightAndMagicBmp.fromFile("path/to/local/file.bmp");

Or parse structure from a byte array:

byte[] someArray = new byte[] { ... };
HeroesOfMightAndMagicBmp data = new HeroesOfMightAndMagicBmp(new ByteBufferKaitaiStream(someArray));

After that, one can get various attributes from the structure by invoking getter methods like:

data.magic() // => get magic
