'  This example requires the Chilkat API to have been previously unlocked.
'  See Compression UnlockComponent for sample code.

'  First create some binary data to compress.
set binData = Server.CreateObject("Chilkat_9_5_0.BinData")

For i = 1 To 16
    success = binData.AppendEncoded("000102030405060708090A0B0C0D0E0F","hex")
Next

set compress = Server.CreateObject("Chilkat_9_5_0.Compression")
compress.Algorithm = "deflate"
compress.EncodingMode = "base64"

uncompressedBytes = binData.GetBinary()

'  Compress and return the compressed bytes in base64 format.
compressedBase64 = compress.CompressBytesENC(uncompressedBytes)
Response.Write "<pre>" & Server.HTMLEncode( "compressed and base64 encoded: " & compressedBase64) & "</pre>"

'  Compress and return in hex format:
compress.EncodingMode = "hex"
compressedHex = compress.CompressBytesENC(uncompressedBytes)
Response.Write "<pre>" & Server.HTMLEncode( "compressed and hex encoded: " & compressedHex) & "</pre>"

'  Now decompress..
set binData2 = Server.CreateObject("Chilkat_9_5_0.BinData")

'  Decompress the base64..
compress.EncodingMode = "base64"
uncompressedBytes = compress.DecompressBytesENC(compressedBase64)
success = binData2.AppendBinary(uncompressedBytes)
'  Show the uncompressed bytes in hex format:
Response.Write "<pre>" & Server.HTMLEncode( binData2.GetEncoded("hex")) & "</pre>"

'  Decompress the hex..
