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.

Perl

use chilkat();

$success = 0;

# 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->new();
$sb = chilkat::CkStringBuilder->new();
$bd = chilkat::CkBinData->new();

# 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 == 0) {
    print $gzip->lastErrorText() . "\r\n";
    exit;
}

# The BinData now contains the Gzip-compressed bytes.
print "Compression successful." . "\r\n";
print "Compressed size (bytes): " . $bd->get_NumBytes() . "\r\n";

# (Optional) Save to a .gz file:
$success = $bd->WriteFile("text.gz");
if ($success == 0) {
    print $bd->lastErrorText() . "\r\n";
    exit;
}

print "Gzip file written to text.gz" . "\r\n";
