Compress Text from StringBuilder to Gzip (BinData Output)

See more Gzip Examples

This example demonstrates how to use the CompressSb method to compress text stored in a StringBuilder into Gzip format.

The text is first converted to its byte representation using the specified character set (in this case, UTF-8). These bytes are then compressed, and the resulting Gzip data is written to a BinData object in memory.

This approach is useful when working with dynamically generated text that you want to compress without first writing it to a file. The example also shows how the compressed data can optionally be saved to a .gz file.

import sys
import chilkat

success = False

# This example demonstrates how to compress text contained in a StringBuilder
# into Gzip format, storing the compressed result in a BinData object.

gzip = chilkat.CkGzip()
sb = chilkat.CkStringBuilder()
bd = chilkat.CkBinData()

# Add some text to the StringBuilder:
sb.Append("The quick brown fox jumps over the lazy dog.")

# Compress the text using UTF-8 encoding:
success = gzip.CompressSb(sb,"utf-8",bd)
if (success == False):
    print(gzip.lastErrorText())
    sys.exit()

# The BinData now contains the Gzip-compressed bytes.
print("Compression successful.")
print("Compressed size (bytes): " + str(bd.get_NumBytes()))

# (Optional) Save to a .gz file:
success = bd.WriteFile("text.gz")
if (success == False):
    print(bd.lastErrorText())
    sys.exit()

print("Gzip file written to text.gz")
