Specifies the compression mode used for the BLOB or varchar field.
property BlobCompressionMode: Byte;
This property specifies compression level for BLOB fields. The correct values are integer numbers in range 0-9. Maximum value of CompressionMode corresponds to slow compression and best compression rate. The zero value means that files will not be compressed. If you need only to store BLOB data, set CompressionMode to 0. Compression rate of the data also depends on selected BlobCompressionAlgorithm.
The value of BlobCompressionMode is ignored unless DataType is not of any Blob or Varchar type.
Look at BLOB and Varchar fields topic in Developer's Guide to learn more about possible settings.
