Using Aspose.Drawing in Azure Function

Azure Functions allows you to quickly create a module to run on the cloud infrastructure.

You can use Aspose.Drawing in your Azure Function to draw vector graphics, text, and generate resulting images as demonstrated in this tutorial.

1. Create a C# function app project.

Create an HTTP trigger function from Azure Functions project template as described in Quickstart: Create your first function in Azure using Visual Studio.

2. Add the Aspose.Drawing package to project dependencies.

3. Add image drawing code.

Replace the main Function1.cs file with the following code that draws a gradient and returns the resulting image for an HTTP request:

4. Add an Aspose.Drawing license file.

Copy your Aspose.Drawing.NET.lic file with Aspose.Drawing licensing information to the project directory, open this file properties from Solution Explorer and set Copy to Output Directory to Copy always.

5. Publish the project to Azure.

Publish your project to Azure as described in Quickstart: Create your first function in Azure using Visual Studio.

6. Test your function in Azure.

In the address bar in the browser, append the string /api/Function1 to the base URL and run the request (the full request will look like https://azurefunctionapp123456789.azurewebsites.net/api/Function1).

The browser will display the drawing result:
