TECLCompressionLevel type

Delphi Database, Delphi Components from ComponentAce

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
