Aspose.Drawing for .NET is a cross-platform 2D drawing engine with System.Drawing compatible API.

Our drawing engine supports rendering vector graphics (such as lines, curves, and figures) and text (in a variety of fonts, sizes, and styles) onto raster images represented by an array of pixels in memory. Images can be saved in some of the popularly used graphics file formats (BMP, PNG, JPEG, GIF, TIFF).

Aspose.Drawing for .NET is a 2D graphics library with System.Drawing compatible API. It allows your cross-platform .NET Apps to render vector graphics such as lines, curves, and figures as well as text onto raster images.

Aspose.Drawing is a pure .NET library that does not rely on any external native rendering engine. It allows running your existing C# and VB Apps on various supported platforms having identical rendering results.

Aspose.Drawing for .NET can be used in .NET Framework, .NET Core or Xamarin applications in Windows, Linux, Android, Azure Functions or Blazor WebAssembly. It can be safely run from any restricted environment such as Windows or ASP.NET service.

With Aspose.Drawing you can create bitmaps from scratch or load from existing files; draw lines, Bézier curves, splines, arcs, rectangles, polygons, eclipses, etc.; work with graphics paths; render text with different fonts and styles. It allows using different pen widths and styles; solid, texture, gradient and hatch brushes; clipping regions and matrix transformations. Images are stored in memory as managed arrays of pixels and can be saved in various image formats including BMP, PNG, JPEG, GIF, and TIFF.

Graphic File Processing Features

• Creating bitmaps from scratch or loading from files.
• Drawing lines, Bézier curves, splines, and arcs.
• Drawing shapes such as rectangle, polygon, eclipse, etc.
• Processing and drawing graphics paths.
• Rendering text with different fonts and styles.
• Using different pen widths and styles.
• Using solid and texture brushes.
• Alpha blending and anti-aliasing lines and shapes.
• Working with clip regions.
• Using affine transformations.

What's new in v22.1.0

Image.Tag Property

Added the Image.Tag property that provides additional data regarding the image.

Improved Performance while Saving in PNG

Performance has been optimized for PNG rendering and saving. The following C# code renders PNG using API:

// Example to create a new drawing in C# .NET and render as a PNG. 
// See https://github.com/aspose-drawing/Aspose.Drawing-for-.NET and https://docs.aspose.com/drawing/net/ for more examples.
// Create a new drawing
Bitmap bitmap = new Bitmap(1000, 800, System.Drawing.Imaging.PixelFormat.Format32bppPArgb);
Graphics graphics = Graphics.FromImage(bitmap);
// Save drawing
bitmap.Save(RunExamples.GetDataDir() + @"drawing.png");

Improved Arc Drawing

Made improvements to the Arc drawing to have a more accurate outcome. The following C# code demonstrates how to draw Arc and save as PNG using API:

// For complete examples and data files, please go to https://github.com/aspose-drawing/Aspose.Drawing-for-.NET

using System.Drawing;

Bitmap bitmap = new Bitmap(1000, 800, System.Drawing.Imaging.PixelFormat.Format32bppPArgb);
Graphics graphics = Graphics.FromImage(bitmap);

Pen pen = new Pen(Color.Blue, 2);
graphics.DrawArc(pen, 0, 0, 700, 700, 0, 180);

bitmap.Save("DrawArc.png");

Supported Read & Write Drawing Formats

BMP, PNG, JPEG, GIF, TIFF

Platform Independence

The project is based on managed .NET core and does not have dependencies on native code and libraries, with the rendering algorithms working the same way on all supported platforms.

Aspose.Drawing for .NET supports any 32-bit or 64-bit operating system where .NET Framework or .NET Core is installed including, but not limited to:

• Microsoft Windows desktop (XP, Vista, 7, 8, 10) and server operating systems (2003, 2008, 2012, 2016, 2019)
• Windows Azure

It also supports .NET Framework version 2.0 and .NET Core 2.0 or later. You can use Aspose.Drawing for .NET to develop applications in any development environment that targets the .NET platform. However, Microsoft Visual Studio 2012, 2013, 2015, 2017, 2019 are explicitly supported.

Get Started

Are you ready to give Aspose.Drawing for .NET a try? Simply execute Install-Package Aspose.Drawing from Package Manager Console in Visual Studio to fetch the NuGet package. If you already have Aspose.Drawing for .NET and want to upgrade the version, please execute Update-Package Aspose.Drawing to get the latest version.

Create New Bitmap using C# Code

You can execute the below code snippet to see how Aspose.Drawing API performs in your own environment or check the GitHub Repository for other common usage scenarios.

// For complete examples and data files, please go to
// https://github.com/aspose-drawing/Aspose.Drawing-for-.NET
Bitmap bitmap = new Bitmap(1000, 800, System.Drawing.Imaging.PixelFormat.Format32bppPArgb);
Graphics graphics = Graphics.FromImage(bitmap);

Pen pen = new Pen(Color.FromKnownColor(KnownColor.Blue), 2);
graphics.DrawArc(pen, 0, 0, 700, 700, 0, 180);

bitmap.Save(RunExamples.GetDataDir() + @"LinesCurvesShapes\DrawArc_out.png");
