Let's dive into the specific action available and explore how you can leverage it in your projects.

Generate Image from Excalidraw Notes

The "Generate Image from Excalidraw Notes" action allows you to create visual representations based on Excalidraw-style sketches. This action is designed to solve the challenge of converting conceptual sketches into detailed images, making it an essential tool for developers looking to enhance their applications with rich visual content.

Input Requirements

To use this action, you need to provide a structured input that includes the following key elements:

  • Prompt: A detailed description of what the image should depict, ideally including specific styles or objects to enhance the output’s relevance.
  • Image Aspect Ratio: Choose from predefined aspect ratios or specify a custom size for your generated image.
  • Output Quality: Specify the desired quality level for the images produced, ranging from 0 to 100.
  • Image Output Format: Select the format for the output images (e.g., webp, jpg, png).
  • Additional parameters include options for controlling randomness, guidance scale, and inference steps, which can be tailored to suit your specific requirements.

Expected Output

Upon successful execution, the action returns an array of image URLs corresponding to the generated visuals. Each URL points to a high-quality image created based on the provided prompt.

Example Input

{
  "prompt": "A handrawn sketch in the style of EXCALIDRAW shows a computer operating system with title text “LLM OS”. The sketch is divided into sections, each with a different function of the operating system. The sections include keyboard shortcuts, game controller, and a summary of the operating system. The drawing is done in a cartoon style, making it visually appealing and easy to understand.",
  "outputsCount": 4,
  "guidanceScale": 3.5,
  "outputQuality": 100,
  "imageAspectRatio": "1:1",
  "imageOutputFormat": "jpg"
}

Example Output

import requests
import json

# Replace with your actual Cognitive Actions API key and endpoint
# Ensure your environment securely handles the API key
COGNITIVE_ACTIONS_API_KEY = "YOUR_COGNITIVE_ACTIONS_API_KEY"
# This endpoint URL is hypothetical and should be documented for users
COGNITIVE_ACTIONS_EXECUTE_URL = "https://api.cognitiveactions.com/actions/execute"

action_id = "69a3a8de-324f-42e6-939b-6410e5deabe0" # Action ID for: Generate Image from Excalidraw Notes
