(Chilkat2-Python) Compress Bytes to Base64 (or any other encoding)

Compresses bytes to base64 or any other encoding. Also decompress to return the original.

Chilkat2 Python Downloads install with pip pip3 install chilkat2 or download... Python Module for Windows, Linux, Alpine Linux, MacOS, Solaris

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

# First create some binary data to compress.
binData = chilkat2.BinData()

for i in range(1,17):
    binData.AppendEncoded("000102030405060708090A0B0C0D0E0F","hex")

compress = chilkat2.Compression()
compress.Algorithm = "deflate"
compress.EncodingMode = "base64"

# uncompressedBytes is a memoryview
uncompressedBytes = binData.GetBinary()

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

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

# Now decompress..
binData2 = chilkat2.BinData()

# Decompress the base64..
compress.EncodingMode = "base64"
# uncompressedBytes is a memoryview
uncompressedBytes = compress.DecompressBytesENC(compressedBase64)
binData2.AppendBinary(uncompressedBytes)
# Show the uncompressed bytes in hex format:
print(binData2.GetEncoded("hex"))
print("--")

# Decompress the hex..
compress.EncodingMode = "hex"
# uncompressedBytes is a memoryview
uncompressedBytes = compress.DecompressBytesENC(compressedHex)
binData2.Clear()
binData2.AppendBinary(uncompressedBytes)
# Show the uncompressed bytes in hex format:
print(binData2.GetEncoded("hex"))
print("--")
