CompressionLevel

The algorithm and level properties are used together in the following combinations.

• Disabled—Compression is disabled if the level equals -1. The algorithm value is ignored when level equals -1.
• Low compression—Compression is enabled at a low level if level equals 0 and algorithm equals 10.
• Medium compression—Compression is enabled at a medium level if level equals 1 and algorithm equals 21.
• High compression—Compression is enabled at a high level if level equals 2 and algorithm equals 31.
