ZLib.TCompressionLevel Enumeration

TCompressionLevel indicates the type of compression algorithm to be used when creating a compressed data stream.

Pascal

TCompressionLevel = (
  clNone,
  clFastest,
  clDefault,
  clMax
);

C++

enum TCompressionLevel {
  clNone,
  clFastest,
  clDefault,
  clMax
};

ZLib

The following table lists the possible values:

Value	Meaning
clNone	Specifies no compression; data is merely copied to the output stream.
clFastest	Specifies fastest compression, resulting in a larger archive.
clDefault	Compromise between speed and amount of compression.
clMax	Specifies maximum compression, resulting in a longer time to perform the operation.
