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.

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

my $gzip = Chilkat2::Gzip->new;
my $sb = Chilkat2::StringBuilder->new;
my $bd = Chilkat2::BinData->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:
my $success = $gzip->CompressSb($sb, 'utf-8', $bd);
if (!$success) {
    print $gzip->LastErrorText, "\n";
    exit;
}

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

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

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