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. There's lots of great options for image processing on. NOTE that on Ubuntu (and other Linuxes) you may need to install some native dependencies as System.Drawing sits on top of native libraries sudo apt install libc6-dev Graphics.DrawImage(image, 0, 0, width, height) Graphics.CompositingMode = CompositingMode.SourceCopy Graphics.InterpolationMode = InterpolationMode.HighQualityBicubic Graphics.CompositingQuality = CompositingQuality.HighSpeed Using (var graphics = Graphics.FromImage(resized)) ![]() Using(FileStream pngStream = new FileStream(args,FileMode.Open, FileAccess.Read)) NET Core app and it runs in both Windows and Linux (Ubuntu!) using System Here's a super simple app that resizes a PNG to 128x128. 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. The " Windows Compatibility Pack" is a package meant for developers that need to port existing. Using System.Drawing was one of those things. There is a lot of existing code - mine included - that makes assumptions that. However, since then Microsoft has released to provide access to GDI+ graphics functionality cross-platform.

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. 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.Drawing to do the work.
