func chilkatTest() {
    var success: Bool = false

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

    // Load the data from an existing image.
    let bdImageData = CkoBinData()!
    success = bdImageData.loadFile(path: "qa_data/jpg/kid_blue_coat.jpg")
    if success == false {
        print("\(bdImageData.lastErrorText!)")
        return
    }

    let ai = CkoAi()!

    ai.provider = "openai"

    // Use your provider's API key.
    ai.apiKey = "MY_API_KEY"

    // Choose a model.
    ai.model = "gpt-5"

    let askParams = CkoJsonObject()!
    askParams.updateString(jsonPath: "image.output_format", value: "jpeg")
    ai.setAskParams(json: askParams)

    ai.inputAddImageData(bd: bdImageData, summary: "")
    ai.inputAddText(text: "Modify the image by replacing the blue coat with a Metallica T-shirt.")

    // Give the AI some time (2 minutes).
    ai.idleTimeoutMs = 120000

    // Ask the AI for image output.
    success = ai.ask(outputType: "image")
    if success == false {
        print("\(ai.lastErrorText!)")
        return
    }

    // Get the image response data.;
    success = ai.getOutputBd(bd: bdImageData)
    if success == false {
        print("\(ai.lastErrorText!)")
        return
    }

    bdImageData.writeFile(path: "c:/aaworkarea/out.jpg")
