Description
ZCompressStr returns the compression of a string.
ZCompressStr will return the compressed version of a string specified by s as a pointer to a dynamic array of bytes (TBytes).
The level optional parameter represents the level of compression. ZCompressStr can be called without the level parameter. In this case, level is set to the default value: zcDefault. ZCompressStr may raise an EZCompressionError.
See sample:
function myCompress(mySource: string ): TBytes;
var
compressedString: TBytes;
begin
compressedString:= ZCompressStr(mySource);
Result:= CompressedString;
end;
