CompressionLevel enumeration

Specifies ZIP compression levels for OpenXML file. Higher levels provide better compression at the cost of slower processing.

The CompressionLevel type exposes the following members:

Fields

Field	Description
NONE	No compression is applied. Files are stored as-is.
LEVEL1	Fastest compression with the lowest compression ratio.
LEVEL2	Faster compression with slightly better compression ratio than `CompressionLevel.LEVEL1`.
LEVEL3	Provides better compression than `CompressionLevel.LEVEL2` with moderate performance impact.
LEVEL4	Provides better compression than `CompressionLevel.LEVEL3`.
LEVEL5	Provides improved compression over `CompressionLevel.LEVEL4` with additional processing time.
LEVEL6	Standard compression, offering a good balance between compression speed and file size. The default compression level.
LEVEL7	Provides higher compression than `CompressionLevel.LEVEL6` with slower processing.
LEVEL8	Provides higher compression than `CompressionLevel.LEVEL7`.
LEVEL9	Maximum compression. Produces the smallest file size with the slowest processing speed.
