# See Global Unlock Sample for sample code.

# First create some binary data to compress.
$binData = New-Object Chilkat.BinData

    $binData.AppendEncoded("000102030405060708090A0B0C0D0E0F","hex")
}

$compress = New-Object Chilkat.Compression
$compress.Algorithm = "deflate"
$compress.EncodingMode = "base64"

$uncompressedBytes = $binData.GetBinary()

# Compress and return the compressed bytes in base64 format.
$compressedBase64 = $compress.CompressBytesENC($uncompressedBytes)
$("compressed and base64 encoded: " + $compressedBase64)

# Compress and return in hex format:
$compress.EncodingMode = "hex"
$compressedHex = $compress.CompressBytesENC($uncompressedBytes)
$("compressed and hex encoded: " + $compressedHex)

# Now decompress..
$binData2 = New-Object Chilkat.BinData

# Decompress the base64..
$compress.EncodingMode = "base64"
$uncompressedBytes = $compress.DecompressBytesENC($compressedBase64)

# Decompress the hex..

$binData2.Clear()
$binData2.AppendBinary($uncompressedBytes)
# Show the uncompressed bytes in hex format:
