- The Core Graphics framework is based on the Quartz advanced drawing engine. It provides low-level, lightweight 2D rendering with unmatched output fidelity. You use this framework to handle path-based drawing, transformations, color management, offscreen rendering, patterns, gradients and shadings, image data management, image creation,.
- Core Image is a powerful framework offering image processing and analysis for both iOS and OS X. It offers Swift developers a simple API to a wide range of image based effects. Core Image for Swift is a comprehensive guide to Core Image for iOS Swift developers. It covers all areas of working with Core Image for processing still images.
- There's lots of great options for image processing on.NET Core now! It's important to understand that this System.Drawing layer is great for existing System.Drawing code, but you probably shouldn't write NEW image management code with it. Instead, consider one of the great other open source options.

I've been doing .NET image processing since the beginning. In fact I wrote about it over 13 years ago on this blog when I talked about Compositing two images into one from the ASP.NET Server Side and in it I used System.Drawingto do the work. For over a decade folks using System.Drawing were just using it as a thin wrapper over GDI (Graphics Device Interface) which were very old Win32 (Windows) unmanaged drawing APIs. We use them because they work fine.

Core Image is an image processing and analysis technology that provides high-performance processing for still and video images. Use the many built-in image filters to process images and build complex effects by chaining filters. For details, see Core Image Filter Reference. Current supported version 0.6.2. What is OpenCore and who is this guide for. OpenCore is what we refer to as a 'boot loader', this is a complex piece of software that we use to prepare our systems for macOS.
For a while there was a package called CoreCompat.System.Drawing that was a .NET Core port of a Mono version of System.Drawing.
However, since then Microsoft has released System.Drawing.Common to provide access to GDI+ graphics functionality cross-platform.
There is a lot of existing code - mine included - that makes assumptions that .NET would only ever run on Windows. Using System.Drawing was one of those things. The 'Windows Compatibility Pack' is a package meant for developers that need to port existing .NET Framework code to .NET Core. Some of the APIs remain Windows only but others will allow you to take existing code and make it cross-platform with a minimum of trouble.
Here's a super simple app that resizes a PNG to 128x128. However, it's a .NET Core app and it runs in both Windows and Linux (Ubuntu!)
Here it is running on Ubuntu:
NOTE that on Ubuntu (and other Linuxes) you may need to install some native dependencies as System.Drawing sits on top of native libraries

- ImageSharp - A cross-platform library for the processing of image files; written in C#
- Compared to
System.Drawing
ImageSharp has been able to develop something much more flexible, easier to code against, and much, much less prone to memory leaks. Gone are system-wide process-locks; ImageSharp images are thread-safe and fully supported in web environments.
- Compared to
Here's how you'd resize something with ImageSharp:
- Magick.NET -A .NET library on top of ImageMagick
- SkiaSharp - A .NET wrapper on top of Google's cross-platform Skia library
It's awesome that there are so many choices with .NET Core now!

Disclaimer: I am not on the .NET Core Team. I used the tools available publicly and have no insights into the future of .NET Core. It looks very bright though. :)
The working source code for this project can be found here.
Intro
A complete list of post in this series is included below :
In this post, we’re going to look at running the app from the command line and then the Mac.
Running the App in the Windows Command Prompt
While you can obviously run the app inside of Visual Studio with the F5 command. You should also know that you can run the app inside of the console. Before we begin, make sure you have the app found here. After opening the app or downloading it, open the folder containing the project in the command prompt.
You can run your application here by simply typing :
You will the following output :
The exact same result from running the console app in Visual Studio.
Using dotnet publish to get the app ready for Mac
Go ahead and type
dotnet publish
on the command prompt and then type tree
to look at your directory listing as shown below :You should see the publish directory. Navigate into it and list out the files in the directory :
Take note that the dlls listed below are related to the package reference that we added in the last blog post.

- Newtonsoft.Json.dll
- System.Runtime.Serialization.Primitives.dll
This only leaves the NetCoreConsoleApp.dll which is the Console application that we can run on a Mac (or any other platform that supports .NET Core).
Running the app on a Mac
Finally! It is about time you might say. I agree. Before you can run the app on your Mac, you’re going to need to head back over to the .NET Core downloads page and install OpenSSL and then the SDK (or runtime) if you remember the difference from the first post.
To run this on your Mac, you’ll need to copy the ‘publish’ folder to your Mac. Then open Terminal and you can run the app by just typing :
This is awesome! Now you have an app that run on another platform and you used your existing .NET skillset to create it. I’m LOVING .NET Core!
