Question 1

How to draw a gradient-filled circle in NGraphics?

Accepted Answer

Use a RadialGradientBrush or LinearGradientBrush with the FillEllipse method. For example, create a brush with gradient stops and apply it to an ellipse, as shown in the Pens and Brushes section for similar effects.

Question 2

NGraphics vs SkiaSharp: which is better for .NET graphics?

Accepted Answer

NGraphics offers a simpler, more unified API for cross-platform vector graphics with retained mode support, while SkiaSharp is more feature-rich and widely used but can be heavier. Choose NGraphics for lightweight, consistent APIs across .NET platforms, especially with Xamarin.

Question 3

Can NGraphics handle SVG animation?

Accepted Answer

No, NGraphics focuses on static vector graphics rendering and SVG import/export. It does not support SVG animations; you would need to implement animation separately using its drawing API or combine it with other libraries.

Question 4

How to export a drawing to PNG in NGraphics?

Accepted Answer

Create an IImageCanvas using Platforms.Current.CreateImageCanvas, draw your graphics, then call GetImage().SaveAsPng() with a file path. The Getting Started example demonstrates this with a simple house drawing.

Question 5

Is NGraphics good for game development?

Accepted Answer

It's suitable for 2D vector-based UI elements or simple graphics in games, but not for high-performance 3D rendering or complex game engines. Use it for HUDs or menu graphics where cross-platform consistency is key.

Question 6

How to use NGraphics with Xamarin.Forms?

Accepted Answer

Integrate by creating custom renderers or views that use NGraphics canvases for drawing. For example, override OnPaint in a custom control to render vector graphics, leveraging the platform-specific canvases like CGContextCanvas for iOS.
