Add missing fields to OutputImageGenerationToolCall

[Androbin]

What:

• Bug Fix
• New Feature

Description:

Add missing fields (action, background, output_format, quality, revised_prompt, size) to OutputImageGenerationToolCall (available in the official Python SDK).

Example Request:

import openai
response = openai.responses.create(
    model="gpt-5",
    input="Generate an image of gray tabby cat hugging an otter with an orange scarf",
    tools=[{"type": "image_generation"}],
)
image_generation_call = next(output for output in response.output if output.type == "image_generation_call")
print(image_generation_call)

Example Response:

ImageGenerationCall(
    id='ig_123',
    result='...',
    status='completed',
    type='image_generation_call',
    action='generate',
    background='opaque',
    output_format='webp',
    quality='high',
    revised_prompt='A gray tabby cat hugging an otter. The otter is wearing an orange scarf. Both animals are cute and friendly, depicted in a warm, heartwarming style.',
    size='1536x1024'
)

Could we augment a test and assert on these new properties?

thanks! This looks good, I'll run a quick sample with my test code to confirm before merging. I think I could probably replicate this with my stream image response test - https://github.com/iBotPeaches/openai-php-laravel-test/blob/master/app/Console/Commands/ResponsesStreamImageGenerationTest.php

Confirmed working with a real test.
