Compressed resource data in 'dcmp' (0) format,
as stored in compressed resources with header type 8 and decompressor ID 0.
The 'dcmp' (0) decompressor resource is included in the System file of System 7.0 and later.
This compression format is used for most compressed resources in System 7.0's files.
This decompressor is also included with and used by some other Apple applications,
such as ResEdit.
This compression format supports some basic general-purpose compression schemes, including backreferences to previous data, run-length encoding, and delta encoding. It also includes some types of compression tailored specifically to Mac OS resources, including a set of single-byte codes that correspond to entries in a hard-coded lookup table, and a specialized kind of delta encoding for segment loader jump tables.
Almost all parts of this compression format operate on units of 2 or 4 bytes. As a result, it is nearly impossible to store data with an odd length in this format. To work around this limitation, odd-length resources are padded with an extra byte before compressing them with this format. This extra byte is ignored after decompression, as the real (odd) length of the resource is stored in the compressed resource header.
The 'dcmp' (1) compression format (see dcmp_1.ksy) is very similar to this format,
with the main difference that it operates mostly on single bytes rather than two-byte units.
This page hosts a formal specification of Compressed Macintosh resource data, Apple `'dcmp' (0)` format using Kaitai Struct. This specification can be automatically translated into a variety of programming languages to get a parsing library.
