How to Convert DWT to PNG Using C#

In order to convert DWT to PNG, we’ll use Aspose.CAD for .NET API which is a feature-rich, powerful and easy to use document manipulation and conversion API for C# platform. Open NuGet package manager, search for Aspose.CAD and install. You may also use the following command from the Package Manager Console.

Package Manager Console Command
PM> Install-Package Aspose.CAD

Steps to Convert DWT to PNG via C#

.NET programmers can easily load & convert DWT files to PNG in just a few lines of code.

Load DWT file with Image.Load method
Set an object of CadRasterizationOptions with page height & width
Create an instance of PngOptions class and set its VectorRasterizationOptions property
Call Image.Save method while passing the resultant file path & object of PngOptions

System Requirements

Before running the .NET conversion code, make sure that you have the following prerequisites.

Microsoft Windows or a compatible OS with .NET Framework, .NET Core.
Development environment like Microsoft Visual Studio.
Aspose.CAD for .NET DLL referenced in your project.

This sample code shows DWT to PNG C# Conversion

	// load DWT in an instance of Image via its Load method
	using (var image = Image.Load("template.dwt"))
	{
	// create an instance of CadRasterizationOptions and set page height & width
	var rasterizationOptions = new ImageOptions.CadRasterizationOptions()
	{
	PageWidth = 1600,
	PageHeight = 1600
	};

	// create an instance of PngOptions
	var options = new ImageOptions.PngOptions();

	// set the VectorRasterizationOptions property as CadRasterizationOptions
	options.VectorRasterizationOptions = rasterizationOptions;

	// export DWT to PNG
	image.Save("output.png", options);
	}

DWT What is DWT File Format?

A DWT file is an AutoCAD drawing template file that is used as starter for creating drawings that can be saved as DWG files. Such template files provide initial settings such as unit types, precision required, title blocks, layer names, line types and other similar information for lateral conversion to proper drawing files. Both AutoCAD and CoreCAD can be used to read the template files and utilize them further. In simple words, a DWT is a DWG with pre-defined read-only attributes in the same way as a MSWord DOT file is to a DOC file.

PNG What is PNG File Format?

A PNG (Portable Network Graphics) file is a raster image file format that uses lossless compression. This file format was created as a replacement of Graphics Interchange Format (GIF) and has no copyright limitations. However, PNG file format does not support animations. PNG file format supports lossless image compression that makes it popular among its users. With the passage of time, PNG has evolved as one of the widely used image file formats.
