What compression algorithms does CDF support?
Compression may be specified for a single-file CDF and the CDF library can be instructed to compress a CDF as it is written to disk. This compression occurs transparently to the user. When a compressed CDF is opened, it is automatically decompressed by the CDF library. An application does not have to even know that a CDF is compressed. Any type of access is allowed on a compressed CDF. When a compressed CDF is closed by an application, it is automatically recompressed as it is written back to disk. The individual variables of a CDF can also be compressed. . The CDF library handles the compression and decompression of the variable values transparently. The application does not have to know that the variable is compressed as it accesses the variable’s values. The following compression algorithms are supported by the CDF library: – Run-Length Encoding – Huffman – Adaptive Huffman – GZIP See chapter 2 of the CDF User’s Guide for more detailed information for the compression algorithms ment
