Packages

• ImageSharp.Web
  • Contains the middleware to integrate a dynamic image manipulation workflow into an ASP.NET Core application.

Once installed you will need to add the following code to ConfigureServices in your Startup.cs file.

This installs the the default service and options.

// Add the default service and options.
services.AddImageSharp();

Or add the default service and custom options.

// Add the default service and custom options.
services.AddImageSharp(
    options =>
        {
            // You only need to set the options you want to change here.
            options.Configuration = Configuration.Default;
            options.MaxBrowserCacheDays = 7;
            options.MaxCacheDays = 365;
            options.CachedNameLength = 8;
            options.OnParseCommands = _ => { };
            options.OnBeforeSave = _ => { };
            options.OnProcessed = _ => { };
            options.OnPrepareResponse = _ => { };
        });

Or you can fine-grain control adding the default options and configure other services.

// Fine-grain control adding the default options and configure other services.
services.AddImageSharp()
        .RemoveProcessor<FormatWebProcessor>()
        .RemoveProcessor<BackgroundColorWebProcessor>();

There are also factory methods for each builder that will allow building from configuration files.

// Use the factory methods to configure the PhysicalFileSystemCacheOptions
services.AddImageSharpCore(
    options =>
        {
            options.Configuration = Configuration.Default;
            options.MaxBrowserCacheDays = 7;
            options.MaxCacheDays = 365;
            options.CachedNameLength = 8;
            options.OnParseCommands = _ => { };
            options.OnBeforeSave = _ => { };
            options.OnProcessed = _ => { };
            options.OnPrepareResponse = _ => { };
        })
    .SetRequestParser<QueryCollectionRequestParser>()
    .SetMemoryAllocator(provider => ArrayPoolMemoryAllocator.CreateWithMinimalPooling())
    .Configure<PhysicalFileSystemCacheOptions>(options =>
    {
        options.CacheFolder = "different-cache";
    })
    .SetCache<PhysicalFileSystemCache>()
    .SetCacheHash<CacheHash>()
    .AddProvider<PhysicalFileSystemProvider>()
    .AddProcessor<ResizeWebProcessor>()
    .AddProcessor<FormatWebProcessor>()
    .AddProcessor<BackgroundColorWebProcessor>();

Manual build

If you prefer, you can compile ImageSharp.Web yourself (please do and help!), you'll need:

• Visual Studio 2017 (or above)
• The .NET Core SDK Installer - Non VSCode link.

Alternatively on Linux you can use:

• Visual Studio Code with C# Extension
• .Net Core

To clone it locally click the "Clone in Windows" button above or run the following git commands.

git clone https://github.com/SixLabors/ImageSharp.Web
