# This example assumes the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

sb = chilkat.CkStringBuilder()

for i in range(1,21):
    sb.Append("This is the original uncompressed string.\r\n")

compress = chilkat.CkCompression()
compress.put_Algorithm("deflate")
# Indicate that the utf-8 byte representation of the string should be compressed.
compress.put_Charset("utf-8")

compressedBytes = chilkat.CkByteData()
success = compress.CompressString(sb.getAsString(),compressedBytes)

# If the compressed data is desired in string format, then get the base64 representation of the bytes.
compress.put_EncodingMode("base64")
compressedBase64 = compress.compressStringENC(sb.getAsString())
print("Compressed Bytes as Base64: " + compressedBase64)

# Now decompress...
decompressedString = compress.decompressString(compressedBytes)
print("The original string after decompressing from binary compressed data:")
print(decompressedString)

# To decompress from Base64...
compress.put_EncodingMode("base64")
decompressedString = compress.decompressStringENC(compressedBase64)
print("The original string after decompressing from Base64:")
print(decompressedString)
