Pollinations Watermark is a Node.js application that generates watermarked images using the Express framework, Axios for making HTTP requests, and Sharp for image processing. The application downloads an image from a given URL, crops it, and adds a watermark to the resulting image. This documentation provides an overview of the application's code structure and usage.

1. Clone the repository:

   git clone https://github.com/sachnun/pollinations_watermark.git

2. Navigate to the project directory:

   cd pollinations_watermark

3. Install the dependencies:

   npm install

1. Start the application:

   npm start

2. The server will start running on port 3000. You can access the root endpoint at http://localhost:3000/.

3. To generate a watermarked image, make a GET request to the /image/:parameter endpoint, where :parameter represents the desired image parameter. The application will download the image from the Pollinations AI website, crop it, add a watermark, and return the resulting image.

   Example request:

   GET /image/parameter-value

   Replace parameter-value with the desired image parameter.

4. The resulting watermarked image will be returned as the response.

The application code is structured as follows:

• The required modules (express, axios, and sharp) are imported at the beginning.
• An instance of the Express application is created and assigned to the app variable.
• The port number 3000 is assigned to the port variable.
• The root endpoint / is defined to respond with a JSON message indicating the image generation.
• The /image/:parameter endpoint is defined to handle image generation requests. It downloads the image from the specified Pollinations AI URL, crops it, adds a watermark, and returns the resulting image.
• The server is started by listening on the specified port.

The application relies on the following dependencies:

• Express: A minimal and flexible Node.js web application framework.
• Axios: A promise-based HTTP client for the browser and Node.js.
• Sharp: A high-performance Node.js image processing library.

These dependencies are automatically installed when running npm install.

The Pollinations Watermark application allows you to generate watermarked images by downloading an image from a specified URL, cropping it, and adding a watermark. By following the installation and usage instructions, you can easily run the application and integrate it into your own projects.
