Compress Bytes to Base64 (or any other encoding)

See more Compression Examples

Compresses bytes to base64 or any other encoding. Also decompress to return the original. Go

    success := false

    // This example assumes the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    // First create some binary data to compress.
    binData := chilkat.NewBinData()

    var i int
    for i = 1; i <= 16; i++ {
        binData.AppendEncoded("000102030405060708090A0B0C0D0E0F","hex")
    }

    compress := chilkat.NewCompression()
    compress.SetAlgorithm("deflate")
    compress.SetEncodingMode("base64")

    var uncompressedBytes []byte
    uncompressedBytes = binData.GetBinary()

    // Compress and return the compressed bytes in base64 format.
    compressedBase64 := compress.CompressBytesENC(uncompressedBytes)
    fmt.Println("compressed and base64 encoded: ", *compressedBase64)

    // Compress and return in hex format:
    compress.SetEncodingMode("hex")
    compressedHex := compress.CompressBytesENC(uncompressedBytes)
    fmt.Println("compressed and hex encoded: ", *compressedHex)

    // Now decompress..
    binData2 := chilkat.NewBinData()

    // Decompress the base64..
    compress.SetEncodingMode("base64")
    uncompressedBytes = compress.DecompressBytesENC(*compressedBase64)
    binData2.AppendBinary(uncompressedBytes)
    // Show the uncompressed bytes in hex format:
    fmt.Println(*binData2.GetEncoded("hex"))
    fmt.Println("--")

    // Decompress the hex..
    compress.SetEncodingMode("hex")
    uncompressedBytes = compress.DecompressBytesENC(*compressedHex)
    binData2.Clear()
    binData2.AppendBinary(uncompressedBytes)
    // Show the uncompressed bytes in hex format:
    fmt.Println(*binData2.GetEncoded("hex"))
    fmt.Println("--")

    binData.DisposeBinData()
    compress.DisposeCompression()
    binData2.DisposeBinData()
