imageflow-dotnet-server | A super-fast image server for ASP.NET

You can look at examples/Imageflow.Server.ExampleMinimal to see the result. These steps assume you want to serve and modify images from the wwwroot folder. You can call .SetMapWebRoot(false).MapPath("/", physicalPath) to map a different physical folder. For examples on serving files from S3 or Azure, see the full example after this.
Create a new ASP.NET Core 3.1 project using the Empty template.
Create a directory called "wwwroot" and add a file "image.jpg"
Install Imageflow.Server dotnet add package Imageflow.Server
Open Startup.cs and edit the Configure method. Add app.UseImageflow(new ImageflowMiddlewareOptions() .SetMapWebRoot(true) .SetMyOpenSourceProjectUrl("https://github.com/my/project"));
Replace the endpoint with something that generates an image tag, like app.UseEndpoints(endpoints => { endpoints.MapGet("/", async context => { context.Response.ContentType = "text/html"; await context.Response.WriteAsync("<img src=\"image.jpg?width=450\" />"); }); });
Run your project and see the image be dynamically resized.
If you're not open-sourcing your project, get a trial license key: app.UseImageflow(new ImageflowMiddlewareOptions() .SetMapWebRoot(true) .SetLicenseKey(EnforceLicenseWith.RedDotWatermark, "License 50913....")); Then visit /imageflow.license to verify your license status. This page will be publicly available and show whether you are choosing AGPLv3 mode or using a license key.
