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∑∞T0ƒd Wÿ" ) ]
will result in the decompressed string: “123456789 123456789 123456789”
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.
