Usage
Setup
Install the StableDiffusion.NET-Nuget and at least one of the Backend-Packages.
StableDiffusion.NET is using semantic versioning. Backend-packages are compatible as long as the version does only differ in the last digit.
If GPU-support is available it will prefer this over CPU.
If you want to add your own native-libraries or need more control over which backend to load, check the static Backends class.
Example
1. Create a model
stable diffusion:
// Enable the Log- and Progress-events StableDiffusionCpp.InitializeEvents(); // Register the Log and Progress-events to capture stable-diffusion.cpp output StableDiffusionCpp.Log += (_, args) => Console.WriteLine($"LOG [{args.Level}]: {args.Text}"); StableDiffusionCpp.Progress += (_, args) => Console.WriteLine($"PROGRESS {args.Step} / {args.Steps} ({(args.Progress * 100):N2} %) {args.IterationsPerSecond:N2} it/s ({args.Time})"); Image<ColorRGB>? treeWithTiger; // Load a StableDiffusion model in a using block to unload it again after the two images are created using (DiffusionModel sd = new(DiffusionModelParameter.Create() .WithModelPath(@"<path to model>") // .WithVae(@"<optional path to vae>") .WithMultithreading() .WithFlashAttention())) { // Create a image from a prompt Image<ColorRGB>? tree = sd.GenerateImage(ImageGenerationParameter.TextToImage("A beautiful tree standing on a small hill").WithSDXLDefaults()); // (optional) Save the image (requires the HPPH System.Dawing or SkiaSharp extension) File.WriteAllBytes("image1.png", tree.ToPng()); // Use the previously created image for an image-to-image creation treeWithTiger = sd.GenerateImage(ImageGenerationParameter.ImageToImage("A cute tiger in front of a tree on a small hill", tree).WithSDXLDefaults()); File.WriteAllBytes("image2.png", treeWithTiger.ToPng()); } // Load the qwen image edit model using DiffusionModel qwenContext = new(DiffusionModelParameter.Create() .WithDiffusionModelPath(@"<Qwen-Image-Edit-2509-path>") .WithQwen2VLPath(@"<Qwen2.5-VL-7B-Instruct-path>") .WithQwen2VLVisionPath(@"<Qwen2.5-VL-7B-Instruct.mmproj-path>") .WithVae(@"<qwen_image_vae-path>") .WithMultithreading() .WithFlashAttention() .WithFlowShift(3) .WithOffloadedParamsToCPU() .WithImmediatelyFreedParams()); // Perform an edit on the previously created image Image<ColorRGB>? tigerOnMoon = qwenContext.GenerateImage(ImageGenerationParameter.TextToImage("Remove the background and place the tree and the tiger on the moon.") .WithSize(1024, 1024) .WithCfg(2.5f) .WithSampler(Sampler.Euler) .WithRefImages(treeWithTiger)); File.WriteAllBytes("image3.png", tigerOnMoon.ToPng());
To process the resulting image further you can write your own extensions or install one of the HPPH-extension sets:
HPPH.System.Drawing
HPPH.SkiaSharp
