Skia VS nanovg

Android uses JNI to call native c functions to handle in scaling in pretty much any container derived from View. These C functions are provided by SKIA open source API. The specific function you're looking for is ScalePixels . They say that they use Bicubic in the comments

Flutter is much closer to a "game engine" as it draws it's components using Skia [1] compared to e.g. React Native that creates platform native elements. So you are right, you won't get the underlying platform's widgets. Flutter should act as an intermediary and make this as frictionless as possible though so OS level changes will be propagated or exposed by Flutter or you app directly accesses them but I have no practical experiance in this.

This is not always so cut and dry awful as you might think though. The platform native widgets also have limitations and expectations that might not fit your vision of the app so even fully "native" apps might re-invent the wheel in a couple of places to make things work as they want. Also I've hardly ever come accross an application that works by just combining the basic platform widgets and not look and feel pretty basic.

Also cross platform apps not respecting e.g. Zoom, Resolution, Orientation, A11y, etc. is more often than not, just the developer's not implementing the required things. The framework might support all of these use-cases but not fully automatic in some cases.

Chrome uses Skia which AFAIK is GPU accelerated. Not sure about the SVG part though.

I took a look at using Skia, but the C bindings are marked as not stable and it does not look like an easy to distribute library (plus compiling it takes a long time).

https://skia.org/ is the 2D Graphics library which is used by Chrome/Firefox/Flutter/Android

https://skia.org/ This is used by the sublime editor, so I think it'll match your use-case.

You could look into Skia (BSD), it's used in Chrome, Flutter, Firefox and I think LibreOffice also uses it for some platforms. The other big alternative I'm aware of is Cairo (LGPL).

I've been creating my own environment for generative art using SkiaSharp, which is a C# wrapper around the Skia 2D graphics library (https://skia.org).

Most browsers use Skia, an open source c++ 2d library

You may find nanovg of interest.

What is your take on the underlying library NanoVG stating

In terms of other people's projects: stb, microui, and nanovg come to mind

My library uses nanovg, a canvas API on top of OpenGL, written in C and stb_truetype for font rasterization.

Probably the easiest would be to use a library like nanovg: https://github.com/memononen/nanovg
