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.

Go

    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.NewGzip()
    sb := chilkat.NewStringBuilder()
    bd := chilkat.NewBinData()

    // 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 {
        fmt.Println(gzip.LastErrorText())
        gzip.DisposeGzip()
        sb.DisposeStringBuilder()
        bd.DisposeBinData()
        return
    }

    // The BinData now contains the Gzip-compressed bytes.
    fmt.Println("Compression successful.")
    fmt.Println("Compressed size (bytes): ", bd.NumBytes())

    // (Optional) Save to a .gz file:
    success = bd.WriteFile("text.gz")
    if success == false {
        fmt.Println(bd.LastErrorText())
        gzip.DisposeGzip()
        sb.DisposeStringBuilder()
        bd.DisposeBinData()
        return
    }

    fmt.Println("Gzip file written to text.gz")

    gzip.DisposeGzip()
    sb.DisposeStringBuilder()
    bd.DisposeBinData()
