- Project mention: Quest for Permissively Licensed PDF Library in C# | news.ycombinator.com | 2025-11-04
It seems the PDFSharp rabbit hole goes even deeper than I've realized!
Latest MigraDoc & PDFSharp seem to have been updated and ported to .NET 6 after a lot of the forks happened, so it was unclear to me whether there's merits in looking at other, mostly abandoned forks.
I might add PdfSharpCore, though the use of SixLabors.ImageSharp and SixLabors.Fonts leads to a disqualification from the "quest", given their custom split license [1]

What is PixiEditor? As the name suggests, it's a 2D editor focused on pixel art. However, it also supports procedural graphics, image editing, vector graphics, and animation. Notably, it's an open-source project under active development, meaning anyone can contribute to its evolution.

SkiaSharp
SkiaSharp is a cross-platform 2D graphics API for .NET platforms based on Google's Skia Graphics Library. It provides a comprehensive 2D API that can be used across mobile, server and desktop models to render images.
If you've read any of the other articles this month, you've likely seen SkiaSharp mentioned already. While drawing and text aren't usually a combination I consider, I figured it was worth a shot. I asked Copilot first for an analysis of what the improvement might be along with a plan.

OpenTK
The Open Toolkit library is a fast, low-level C# wrapper for OpenGL, OpenAL & OpenCL. It also includes windowing, mouse, keyboard and joystick input and a robust and fast math library, giving you everything you need to write your own renderer or game engine. OpenTK can be used standalone or inside a GUI on Windows, Linux, Mac.

The user interface has been entirely developed using immediate mode gui dear-imgui library, with the ImGui.NET wrapper. This allows for a fast and bloat free experience but, at the same time, harder customization for a task of this size, since the library isn't really suited to the development of end-user applications. On the other side, it's what I'm most familiar to work with.

- Project mention: Do you need to be a programmer to contribute to open source projects? | dev.to | 2025-07-08
A common misconception is that only programmers can contribute to open source project. Being a programmer of course make it possible for you to make changes to the source code of the application, but there are tons of other things that need to be done in a project. Especially if it is a large, end-user facing project such as Firefox, VLC, Moodle, or mdbook.
