Decompress Bytes

See more Compression Examples

Demonstrates how to decompress binary data. Swift

func chilkatTest() {
    var success: Bool = false

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

    // See this example to compress bytes: Compress Bytes

    let fac = CkoFileAccess()!

    var compressedBytes: NSData
    compressedBytes = fac.readEntireFile(path: "qa_data/compressed/compressedBmp.dat")
    if fac.lastMethodSuccess != true {
        print("\(fac.lastErrorText!)")
        return
    }

    let compress = CkoCompression()!
    compress.algorithm = "deflate"

    var decompressedBytes: NSData
    decompressedBytes = compress.decompressBytes(bData: compressedBytes)
    if compress.lastMethodSuccess != true {
        print("\(compress.lastErrorText!)")
        return
    }

    success = fac.writeEntireFile(path: "qa_output/decompressed.bmp", fileData: decompressedBytes)
    if fac.lastMethodSuccess != true {
        print("\(fac.lastErrorText!)")
        return
