Convert Microsoft Visio Document to BMP in C#

Developers can convert any Microsoft Visio document to BMP (Bitmap Image File) in C# (or in any other .NET Framework supported language e.g. VB.NET etc.) using Aspose.Diagram which is a light-weight, extensible, easy to use API and helps developers to create, manipulate and convert Microsoft Visio files to various formats on client side and server-side without any need to install Microsoft Visio or using any sort of Microsoft Office automation.

Supported Platforms

Aspose.Diagram supports both .NET and Java platforms. Please see Aspose.Diagram for .NET and Aspose.Diagram for Java for your reference.

For demonstration, we will convert the following sample Microsoft Visio document to BMP in C# using Aspose.Diagram for .NET. However, you can use any Microsoft Visio document of your choice inside the sample code and it will also be converted to BMP fine.
