Uses an AI text prompt and uploaded image data to modify an existing image and receive the modified output. .NET Core C#

bool success = 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.
Chilkat.BinData bdImageData = new Chilkat.BinData();
success = bdImageData.LoadFile("qa_data/jpg/kid_blue_coat.jpg");
if (success == false) {
    Debug.WriteLine(bdImageData.LastErrorText);
    return;
}

Chilkat.Ai ai = new Chilkat.Ai();

ai.Provider = "openai";

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

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

Chilkat.JsonObject askParams = new Chilkat.JsonObject();
askParams.UpdateString("image.output_format","jpeg");
ai.SetAskParams(askParams);

ai.InputAddImageData(bdImageData,"");
ai.InputAddText("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("image");
if (success == false) {
    Debug.WriteLine(ai.LastErrorText);
    return;
}

// Get the image response data.;
success = ai.GetOutputBd(bdImageData);
if (success == false) {
    Debug.WriteLine(ai.LastErrorText);
    return;

bdImageData.WriteFile("c:/aaworkarea/out.jpg");

Debug.WriteLine("Success.");
