How can I convert an image URL from images/generations for use in images/edits?

Below is a breakdown of the steps and a sample solution using Python:

Key Points

• Direct URL Input Not Supported:
  The images/edits endpoint requires you to send a local file upload. You cannot pass a URL directly.

• Convert and Validate:
  You’ll need to download the image from the URL, convert it to a PNG if it isn’t already, and ensure that it’s a square image under 4MB. The API documentation states that the image must be a square PNG image.

Sample Python Workflow

Below is an example that downloads an image from a URL, verifies it's a square, converts it to a PNG (if needed), and saves it locally before uploading:

PYTHONCopied
import requests
from PIL import Image
from io import BytesIO

def download_image(url):
    response = requests.get(url)
    response.raise_for_status()  # Ensure we got a valid response
    return Image.open(BytesIO(response.content))

def ensure_square(image):
    width, height = image.size
    if width != height:
        # Crop to the smallest dimension to make it square
        min_dim = min(width, height)
        left = (width - min_dim) // 2
        top = (height - min_dim) // 2
        right = left + min_dim
        bottom = top + min_dim
        image = image.crop((left, top, right, bottom))
    return image

def convert_to_png(image, output_path):
    # Ensure the image is in RGBA mode for PNG
    if image.mode != "RGBA":
        image = image.convert("RGBA")
    image.save(output_path, format="PNG")

# Example URL returned from images/generations
image_url = "https://example.com/path/to/generated_image.webp"

try:
    img = download_image(image_url)
    img = ensure_square(img)
    output_file = "converted.png"
    convert_to_png(img, output_file)
    print(f"Image saved and converted to PNG: {output_file}")
except Exception as e:
    print("Error processing the image:", e)

Next Steps

Once you have the local file (converted.png in this case), you can pass it to the images/edits endpoint as required by the API. This ensures you’re sending a valid PNG that meets the API’s criteria.

By following these steps, you create a clean and reproducible process for handling images from the generations endpoint so that they can be edited using the images/edits endpoint.
