IFF 24 BIT Data Structure

[Schattenwald]

I am an old Amiga fanboy and I am glad that XnView can generate this format. I have created a series of 24-bit IFF files that are displayed correctly on my old Amigas.

Now I have also started to get into Microsoft C#. I am currently working on a small Windows app that can display these 24-bit IFF files as generated by XnView. I can read the BMHD correctly, but I am struggling with the BODY. The image just turns into data garbage. Unfortunately, the documentation I found on the web doesn't really help me.

Is there any documentation on how these files are structured exactly? I am looking to get an understanding of these files. It would be a good start if I could display them correctly.
