Decompress Gzip Data In-Place Using BinData

See more Gzip Examples

This example demonstrates how to use the UncompressBd method to decompress Gzip data stored in a BinData object.

The compressed .gz file is first loaded into memory. The UncompressBd method then decompresses the data in-place, meaning the original compressed bytes in the BinData object are replaced with the uncompressed data.

After decompression, the example writes the resulting data to a file. This approach is useful when working entirely in memory before saving or further processing the uncompressed data.

Go

    success := false

    // This example demonstrates how to decompress Gzip data stored in a BinData object.
    // The decompression is done in-place, replacing the compressed data with the original data.

    gzip := chilkat.NewGzip()
    bd := chilkat.NewBinData()

    // Load a .gz file into BinData:
    success = bd.LoadFile("example.txt.gz")
    if success == false {
        fmt.Println(bd.LastErrorText())
        gzip.DisposeGzip()
        bd.DisposeBinData()
        return
    }

    fmt.Println("Compressed size (bytes): ", bd.NumBytes())

    // Uncompress the data in-place:
    success = gzip.UncompressBd(bd)
    if success == false {
        fmt.Println(gzip.LastErrorText())
        gzip.DisposeGzip()
        bd.DisposeBinData()
        return
    }

    fmt.Println("Decompressed size (bytes): ", bd.NumBytes())

    // Save the uncompressed data to a file:
    success = bd.WriteFile("example.txt")
    if success == false {
        fmt.Println(bd.LastErrorText())
        gzip.DisposeGzip()
        bd.DisposeBinData()
        return
    }

    fmt.Println("File successfully uncompressed to example.txt")

    gzip.DisposeGzip()
    bd.DisposeBinData()
