require 'chilkat'

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.
bdImageData = Chilkat::CkBinData.new()
success = bdImageData.LoadFile("qa_data/jpg/kid_blue_coat.jpg")
if (success == false)
    print bdImageData.lastErrorText() + "\n";
    exit
end

ai = Chilkat::CkAi.new()

ai.put_Provider("openai")

# Use your provider's API key.
ai.put_ApiKey("MY_API_KEY")

# Choose a model.
ai.put_Model("gpt-5")

askParams = Chilkat::CkJsonObject.new()
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.put_IdleTimeoutMs(120000)

# Ask the AI for image output.
success = ai.Ask("image")
if (success == false)
    print ai.lastErrorText() + "\n";
    exit
end

# Get the image response data.;
success = ai.GetOutputBd(bdImageData)
if (success == false)
    print ai.lastErrorText() + "\n";
    exit

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

print "Success." + "\n";
