SK也对应了文生图的功能，本文中分别使用的是GPT的DALL·E 2和DALL·E 3来生成图版，虽然不如专业的文生图那么专业，但提示词到位，在一些场景中还是可用的。
下面是最简单的文生图的代码实现，通过TextToImage服务来完成生成，GPT中生成图的尺寸要求是：256x256, 512x512, 1024x1024, 1024x1792,'1792x1024]
代码：
public static class TextToImageSample
{public static async Task Exec(){
#pragma warning disable SKEXP0010var builder = Kernel.CreateBuilder().AddOpenAITextToImage(Config.OpenAiKey, modelId: "dall-e-2");
#pragma warning restore SKEXP0010var kernel = builder.Build();var prompt1 = $"背景是白色，用墨水，画一匹腾空跃起的骏马。要求马位中图的中央，显示完整。"; await CreateImageAsync(kernel,prompt1);Console.ReadKey();}private static async Task CreateImageAsync(Kernel kernel,string prompt){
#pragma warning disable SKEXP0001var dallE = kernel.GetRequiredService<ITextToImageService>(); var imageUrl = await dallE.GenerateImageAsync(prompt, 1024, 1024); await DownLoadImageAsync(imageUrl);}private static async Task DownLoadImageAsync(string imageUrl){ var localPath = "downloaded_image.jpg"; using (var client = new HttpClient()) { var response = await client.GetAsync(imageUrl); response.EnsureSuccessStatusCode(); var imageBytes = await response.Content.ReadAsByteArrayAsync(); await File.WriteAllBytesAsync(localPath, imageBytes); Console.WriteLine("图片下载成功，保存在：" + localPath); } Process.Start(new ProcessStartInfo(localPath) { UseShellExecute = true });}}
生成图片：
接下来把上面代码第10行修改成DALL·E 3，来看一下效果：
.AddOpenAITextToImage(key,modelId: "dall-e-3)
