NOTE: this function can only decompress text that was previously compressed with “Encr_Compress” function (ZLIB algorithm). Currently no other algorithms, like ZIP and Stuffit (.sit) are supported.


Set Field [ result ; Encr_Decompress ( "-Unused" ; "xú3426153∑∞T0ƒdWÿ" ) ]

will result in the decompressed string: “123456789 123456789 123456789”

Example 2

In a document database you have defined a text field named “letterCompressed” which contains the main part of a letter, compressed. Then you can define a calculation field:

letterContentsCalc   calculation    Unstored = Encr_Decompress ( "-Unused" ; letterCompressed )

this field will contain the uncompressed version of the contents.
