TECLCompressionLevel type

 


Indicates the compression level.

 

Unit

 

EasyCompression

 

type TECLCompressionLevel = (eclNone, zlibFastest, zlibNormal, ppmNormal, ppmMax, zlibMax, ppmFastest, bzipFastest, bzipNormal, bzipMax);

 

Description

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

Value

Meaning

eclNone

 

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
