How to Use the DALLE3 API Key

There are three API endpoints with regard to DALLE3 API

• Generations: generates an image or images based on an input caption
• Edits: edits or extends an existing image
• Variations: generates variations of an input image

How to Setup DALLE3 API (Easily)

• Import the packages you'll need
• Import your OpenAI API key: You can do this by running export OPENAI_API_KEY="your API key" in your terminal.
• Set a directory to save images to

# imports
from openai import OpenAI  # OpenAI Python library to make API calls
import requests  # used to download images
import os  # used to access filepaths
from PIL import Image  # used to print and edit images

# initialize OpenAI client
client = OpenAI(api_key=os.environ.get("OPENAI_API_KEY", "<your OpenAI API key if not set as env var>"))

# set a directory to save DALL·E images to
image_dir_name = "images"
image_dir = os.path.join(os.curdir, image_dir_name)

# create the directory if it doesn't yet exist
if not os.path.isdir(image_dir):
    os.mkdir(image_dir)

# print the directory to save to
print(f"{image_dir=}")

Image Generations with DALLE3 API

The generation API endpoint creates an image based on a text prompt.

OpenAI's Official API Reference for DALLE3 API

Required inputs:

• prompt (str): A text description of the desired image(s). The maximum length is 1000 characters for dall-e-2 and 4000 characters for dall-e-3.

Optional inputs:

• model (str): The model to use for image generation. Defaults to dall-e-2
• n (int): The number of images to generate. Must be between 1 and 10. Defaults to 1.
• quality (str): The quality of the image that will be generated. hd creates images with finer details and greater consistency across the image. This param is only supported for dall-e-3.
• response_format (str): The format in which the generated images are returned. Must be one of "url" or "b64_json". Defaults to "url".
• size (str): The size of the generated images. Must be one of 256x256, 512x512, or 1024x1024 for dall-e-2. Must be one of 1024x1024, 1792x1024, or 1024x1792 for dall-e-3 models. Defaults to "1024x1024".

    n=2,
    size="1024x1024",
    response_format="url",
)

# print response
print(variation_response)

# save the images
variation_urls = [datum.url for datum in variation_response.data]  # extract URLs
variation_images = [requests.get(url).content for url in variation_urls]  # download images
variation_image_names = [f"variation_image_{i}.png" for i in range(len(variation_images))]  # create names
variation_image_filepaths = [os.path.join(image_dir, name) for name in variation_image_names]  # create filepaths
for image, filepath in zip(variation_images, variation_image_filepaths):  # loop through the variations
    with open(filepath, "wb") as image_file:  # open the file
        image_file.write(image)  # write the image to the file

# print the original image
print(generated_image_filepath)
display(Image.open(generated_image_filepath))

# print the new variations
for variation_image_filepaths in variation_image_filepaths:
    print(variation_image_filepaths)
    display(Image.open(variation_image_filepaths))

How to Edit Image Generated by DALLE3 API

The edit endpoint uses DALL·E to generate a specified portion of an existing image. Three inputs are needed: the image to edit, a mask specifying the portion to be regenerated, and a prompt describing the desired image. API Reference

Required inputs:

• image (str): The image to edit. Must be a valid PNG file, less than 4MB, and square. If mask is not provided, image must have transparency, which will be used as the mask.
• prompt (str): A text description of the desired image(s). The maximum length is 1000 characters.

Optional inputs:

• mask (file): An additional image whose fully transparent areas (e.g. where alpha is zero) indicate where image should be edited. Must be a valid PNG file, less than 4MB, and have the same dimensions as image.
• model (str): The model to use for edit image. Only dall-e-2 is supported at this time.
• n (int): The number of images to generate. Must be between 1 and 10. Defaults to 1.
• size (str): The size of the generated images. Must be one of "256x256", "512x512", or "1024x1024". Smaller images are faster. Defaults to "1024x1024".
• response_format (str): The format in which the generated images are returned. Must be one of "url" or "b64_json". Defaults to "url".
• user (str): A unique identifier representing your end-user, which will help OpenAI to monitor and detect abuse.

Set Edit Area in the DALLE3 API

An edit requires a "mask" to specify which portion of the image to regenerate. Any pixel with an alpha of 0 (transparent) will be regenerated. The code below creates a 1024x1024 mask where the bottom half is transparent.

# create a mask
width = 1024
height = 1024
mask = Image.new("RGBA", (width, height), (0, 0, 0, 1))  # create an opaque image mask

# set the bottom half to be transparent
for x in range(width):
    for y in range(height // 2, height):  # only loop over the bottom half of the mask
        # set alpha (

A) to zero to turn pixel transparent
        alpha = 0
        mask.putpixel((x, y), (0, 0, 0, alpha))

# save the mask
mask_name = "bottom_half_mask.png"
mask_filepath = os.path.join(image_dir, mask_name)
mask.save(mask_filepath)

Perform Edit with DALLE3 API

Now we supply our image, caption and mask to the API to get 5 examples of edits to our image

# edit an image

# call the OpenAI API
edit_response = client.images.edit(
    image=open(generated_image_filepath, "rb"),  # from the generation section
    mask=open(mask_filepath, "rb"),  # from right above
    prompt=prompt,  # from the generation section
    n=1,
    size="1024x1024",
    response_format="url",
)

# print response
print(edit_response)

# save the image
edited_image_name = "edited_image.png"  # any name you like; the filetype should be .png
edited_image_filepath = os.path.join(image_dir, edited_image_name)
edited_image_url = edit_response.data[0].url  # extract image URL from response
edited_image = requests.get(edited_image_url).content  # download the image

with open(edited_image_filepath, "wb") as image_file:
    image_file.write(edited_image)  # write the image to the file

# print the original image
print(generated_image_filepath)
display(Image.open(generated_image_filepath))

# print edited image
print(edited_image_filepath)
display(Image.open(edited_image_filepath))

This section is a continuation of how to perform image edits using the DALL·E API, focusing on saving and displaying the edited images.

After obtaining the edited image from the DALL·E API, as shown in the previous steps, you can proceed to save the image to a designated directory and then display it for verification or further actions. The steps provided illustrate how to manage the image files effectively, ensuring they are accessible for any subsequent processing or review.

Save the Edited Image with DALLE3 API

Once you receive the response from the DALL·E API's edit endpoint, you can save the edited image using the following Python code snippet. This code demonstrates how to extract the image URL from the API response, download the image, and save it to a file within your specified directory.

# Save the edited image
edited_image_name = "edited_image.png"  # Define the filename for the edited image
edited_image_filepath = os.path.join(image_dir, edited_image_name)  # Create the full filepath
edited_image_url = edit_response.data[0].url  # Extract the URL of the edited image from the response

# Download the image from the URL
edited_image = requests.get(edited_image_url).content

# Open the file in binary write mode and save the downloaded image
with open(edited_image_filepath, "wb") as image_file:
    image_file.write(edited_image)

Display the Edited Image

After saving the edited image, you may want to display it within your Jupyter notebook to visually confirm the editing results. The following code snippet uses the Image class from the PIL package to load and display the edited image file.

# Display the edited image
print("Edited Image:")
display(Image.open(edited_image_filepath))

This section of the code reads the edited image from the file you saved earlier and displays it using the display function, which is particularly useful in Jupyter notebooks for inline visualization of images and other multimedia elements.
