IFFChunkTool

IFFChunkTool is a command-line tool for manipulating chunks of IFF files. It is intended mainly to be used for automated processing in scripts, makefiles etc.

With IFFChunkTool one can:

• List chunk IDs, lengths and IFF type.
• Extract specified chunk contents to a file.
• Dump specified chunk contents to standard output in a definable format.
• Insert a new chunk at specified position in file.
• Append a new chunk to a file.
• Replace chunk contents with new data.
• Remove a chunk.

For insert, append and replace, chunk contents may be loaded from a file or specified directly as text.

Requirements

The only requirement is AmigaOS 3.0+. Only standard system libraries are used. Runs on any M680x0 processor (or emulation).

Limitations

Version 0.1 has only LIST and EXTRACT modes implemented.

IFFChunkTool handles only flat IFF FORM files. Compound files like IFF LIST, IFF CAT or nested FORMs are not supported.

Examples of use
