Nice post. Looks like I'll need to update the compatibility list: https://github.com/jpsingleton/ANCLAFS#image-manipulation NB: You shouldn't use System.Drawing in a web app. It can lead to memory leaks and lots of pain. Even the newer WPF equivalents are not safe for use on a web server.
Great to see the positive comments here. ImageSharp is my baby and it fills me with a lot of confidence that it's something that developers both want and need.
Out of curiosity what is your overall vision for the library? Are you looking for a System.Drawing high-level API or more of an OpenCV-like low-level API?
This might sound like a small thing but the .NET image processing stuff has traditionally depended a lot on Windows builtins. Mono shipped an entire mediocre rewrite of GDI (the graphics layer that's been Windows since the early nineties) just to support the .NET Framework image processing stuff. Note: not for image display (which is what GDI is mainly for) - even for headless image processing. In practice this meant…
It may just work on Windows but it won't keep working when used server-side in a web app. MS specifically recommend against using it in ASP.NET. I learned the hard way what happens if you ignore the warnings when I was supporting a site that did this.
Edit: I wrote about image optimization and resizing in chapter four of my book on ASP.NET Core - https://unop.uk/book/

Why would you expect negative comment? .NET Core is a solid platform for web development. It's easy to deploy and relatively fast compared to the usual Python/Ruby/PHP and co... only matched by Java(controlled by Oracle) and Go(which is obnoxious). .NET Core is growing at a fast pace, and it deserves it, C# and F# are phenomenal languages.
This isn't my first rodeo with Hacker News, I've unfortunately had negative responses before when sharing my work.

With your lib and a few hours of work, all that disappeared and CPU went way down. Thanks!
On a side note, users should try to send gratitude to open source authors in general. I know it's hypocritical of me, since I didn't take the time to email you before this! I've done it a few times in the past and the replies I've received indicated that I was the only one to ever thank them! That sucks. I've written some stuff I know more than a few companies built entire products and services with -- I've received about 2 notes in 6-7 years. It's not much but just a bit of thanks really provided motivation.
Cheers to you.
The quality settings should have been standardised to human-perceived image quality, given that's the purpose of an image.

If you don't register a provider you just get plain .NET code running serially (though it may user Vector in future versions).

I know this isn't exactly the right place to ask, but I've had no luck anywhere else...
What are the best resources for someone who wants to move from .NET desktop development to .NET web development? All the popular sites like Udacity and FreeCodeBootcamp rarely (if ever) touch the MS stack. I know this isn't exactly the right place to ask, but I've had no luck anywhere else...
Alternatively, you can just get Visual Studio and use their "ASP.NET Web Application" template and poke through what is generated, if you want something a bit smaller to start with.
