TSFSCompressionLevel type

Top 

Indicates the compression level.

Unit
SingleFileSystem

type TSFSCompressionLevel = (sfsNone, zlibFastest, zlibNormal, ppmNormal, ppmMax, zlibMax, ppmFastest, bzipFastest, bzipNormal, bzipMax);

Description
TSFSCompressionLevel represents the values that may be in the CompressionLevel property of any TSFSBaseCompressedStream descendant. The following table lists all the possible values in the TSFSCompressionLevel type and describes what they indicate in the CompressionLevel property:

Value    Meaning    
sfsNone    No compression   
zlibFastest   ZLib algorithm, Fastest compression   
zlibNormal   ZLib algorithm, Normal balance between speed and compression rate   
zlibMax    ZLib algorithm, Maximum compression, rather slow speed   
ppmFastest   PPM algorithm, Fastest compression
   
ppmNormal   PPM algorithm, Normal balance between speed and compression rate   
ppmMax    PPM algorithm, Maximum compression, rather slow speed   
bzipFastest   BZIP algorithm, Fastest compression
   
bzipNormal   BZIP algorithm, Normal balance between speed and compression rate   
bzipMax   BZIP algorithm, Maximum compression, rather slow speed
