Create Images using Semantic Kernel and Azure Open AI

dotnet AI

In this blog post, we’ll learn how to create images using Semantic Kernel and Azure Open AI in C#. We can use DALL-E model to generate the image. First we need to create a console application, we can use the command dotnet new console and then we need to add the Semantic Kernel nuget package. We can do it with dotnet add package Microsoft.SemanticKernel command.

Now we can write the following code.

#pragma warning disable SKEXP0010,SKEXP0001

using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Logging;
using Microsoft.SemanticKernel;
using Microsoft.SemanticKernel.TextToImage;

var configuration = new ConfigurationBuilder()
    .AddUserSecrets<Program>()
    .Build();

var deploymentName = configuration["Azure:OpenAI:DeploymentName"];
var apiKey = configuration["Azure:OpenAI:ApiKey"];
var endpoint = configuration["Azure:OpenAI:Endpoint"];

var builder = Kernel.CreateBuilder();

builder
    .AddAzureOpenAITextToImage(deploymentName!, endpoint!, apiKey!);

builder.Services.AddLogging(logging => logging.AddConsole());

var kernel = builder.Build();

var textToImage = kernel.GetRequiredService<ITextToImageService>();

var imageUrl = await textToImage.GenerateImageAsync("A cat sitting on a table", 1792, 1024, kernel);

Console.WriteLine($"Here is the generated image URL : {imageUrl}");

The generated image is a URL, which we can download and store in storage account or physical storage and use it. In this example, I am reading the configuration values from dotnet secret store and for logging I am using console.

Here is the updated project file.

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>net8.0</TargetFramework>
    <ImplicitUsings>enable</ImplicitUsings>
    <Nullable>enable</Nullable>
    <UserSecretsId>a6a4fa28-81f3-474f-9934-c0d16051f993</UserSecretsId>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="Microsoft.Extensions.Configuration.UserSecrets" Version="9.0.0" />
    <PackageReference Include="Microsoft.Extensions.Logging.Console" Version="9.0.0" />
    <PackageReference Include="Microsoft.SemanticKernel" Version="1.32.0" />
  </ItemGroup>

</Project>

This way we can generate images using Semantic Kernel and Azure Open AI in C# using DALL-E

Happy Programming
