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