nud2dlib NuGet

This library is a fork of jingwood's d2dlib.

Main difference: This library supports only .NET 5 (d2dlib supports .NET FW and .NET Standard 2.1) and uses the types from System.Numerics.* where appropriate (for example, Vector2 and Matrix3x2). We do this because they are easier to work with and come with intrinsic JIT support (and thus, hardware acceleration).


A .NET library for hardware-accelerated, high performance, immediate mode rendering via Direct2D.

By using the graphics context to draw anything on windows form, control or draw in memory via Direct2D. The graphics interface is designed like the normal Windows Form graphics interface, it's easy-to-learn and user-friendly.

Project Language Description Output DLL
d2dlib VC++ Wrapper host-side library, calling Windows SDK and Direct2D API d2dlib.dll
d2dlibexport C# Wrapper client-side library, export the interface provided from d2dlib d2dlibexport.dll
d2dwinform C# Provides the D2DWinForm and D2DControl classes that use Direct2D hardware-acceleration graphics context during rendering d2dwinform.dll


Get binary from NuGet

install-package nud2dlib

Or install for x64 platform:

install-package nud2dlib-x64


The Direct2D API is a platform-associated API that requires the application to be targeted to either x86 or x64 platform. To run the application uses this library correctly, the Platform target of the project settings must be set to x86 or x64.

Install manually

Learn how to install manually

Getting Started

  1. Make windows form or control inherited from D2DForm or D2DControl class
  2. Override OnRender(D2DGraphics g) method (do not override .NET OnPaint method)
  3. Draw anything inside OnRender method via the g context


Draw rectangle

protected override void OnRender(D2DGraphics g)
  var rect = new D2DRect(0, 0, 10, 10);
  g.DrawRectangle(rect, D2DColor.Red);

Draw ellipse

var ellipse = new D2DEllipse(0, 0, 10, 10);
g.DrawEllipse(ellipse, D2DColor.Gray);

Draw text

g.DrawText("Hello World", D2DColor.Yellow, this.Font, 100, 200);

Using brush object

Solid color brush

var brush = Device.CreateSolidColorBrush(new D2DColor(1, 0, 0.5));
g.DrawEllipse(rect, brush);

Linear and radio gradient brush

var brush = Device.CreateLinearGradientBrush(new D2DPoint(0, 0), new D2DPoint(200, 100),
  new D2DGradientStop[] {
    new D2DGradientStop(0, D2DColor.White),
    new D2DGradientStop(0.5, D2DColor.Green),
    new D2DGradientStop(1, D2DColor.Black),

Draw bitmap

g.DrawBitmap(bmp, this.ClientRectangle);

Convert GDI+ bitmap to Direct2D bitmap for getting high-performance rendering

// convert to Direct2D bitmap
var d2dbmp = Device.CreateBitmapFromGDIBitmap(gdiBitmap);

// draw Direct2D bitmap
g.DrawBitmap(d2dbmp, this.ClientRectangle);

Drawing on GDI+ bitmap

// create and draw on GDI+ bitmap
var gdiBmp = new Bitmap(1024, 1024);
using (Graphics g = Graphics.FromImage(gdiBmp))
  g.DrawString("This is GDI+ bitmap layer", new Font(this.Font.FontFamily, 48), Brushes.Black, 10, 10);

// draw memory bitmap on screen
g.DrawBitmap(gdiBmp, this.ClientRectangle);

Learn more about Bitmap. See Example code

Drawing on Direct2D memory bitmap

var bmpGraphics = this.Device.CreateBitmapGraphics(1024, 1024);
bmpGraphics.FillRectangle(170, 790, 670, 80, new D2DColor(0.4f, D2DColor.Black));
bmpGraphics.DrawText("This is Direct2D device bitmap", D2DColor.Goldenrod, this.Font, 180, 800);

// draw this device bitmap on screen
g.DrawBitmap(bmpGraphics, this.ClientRectangle);

Note: When creating a Direct2D Device bitmap, do not forget call BeginRender and EndRender method.

Using transform

By calling PushTransform and PopTransform to make a transform session.


// rotate 45 degree
g.RotateTransform(45, centerPoint);

g.DrawBitmap(mybmp, rect);
