Description

This pull request introduces improved handling of ICC color profiles and default encoder settings for web image processing in ImageSharp.Web. It adds new sample images and UI for testing ICC profile handling, and updates the middleware to better manage color profile conversion and compression settings for JPEG, PNG, and WebP formats.

ICC Profile Handling and Sample Updates:

• Added a new section to the sample app UI (Index.cshtml) to demonstrate ICC profile handling, including new test images and scenarios for both JPEG and WebP output formats.
• Added a new sample image issue_2723.jpg to wwwroot for use in ICC profile testing.

Middleware and Configuration Enhancements:

• Updated ImageSharpMiddleware to set ColorProfileHandling dynamically: if using the default configuration, color profiles are converted to avoid color loss in JPEGs; otherwise, profiles are compacted to remove unnecessary metadata.
• Modified ImageSharpMiddlewareOptions to use a custom default Configuration with optimized encoder settings for JPEG (quality 75, progressive, YCbCr), PNG (best compression, adaptive filter), and WebP (quality 75, best quality method). [1] [2] [3]
• Added imports for specific format encoders in ImageSharpMiddlewareOptions.cs to support the new configuration.
