Convert CGM file to DXF via C#
Export CGM to DXF within .NET applications without using Adobe® Acrobat Reader or any other third party applications
With Aspose.Total for .NET, converting CGM to DXF images in any .NET application is a breeze. It can be achieved in just two straightforward steps. The first step involves using Aspose.PDF for .NET to export CGM files to JPEG format. Then, in the second step, Aspose.Imaging for .NET Image Processing API comes into play to convert the JPEG image to DXF.
By combining the functionality of Aspose.PDF for .NET and Aspose.Imaging for .NET, developers can seamlessly convert CGM files to DXF images within their .NET applications. Aspose.Total for .NET provides a comprehensive suite of libraries that handle different file formats, offering developers a convenient solution for document manipulation, creation, conversion, rendering, and more.
Convert CGM file to DXF via .NET
- Open CGM file using Document class
- Initialize JpegDevice class object and render CGM to JPEG by using Process method
- Load JPEG file by using Image class
- Save the document to DXF format using Save method
Conversion Requirements
Install from command line as nuget install Aspose.Total or install directly from Package Manager Console of Visual Studio.
Two Aspose.Total for .NET child APIs, Aspose.PDF for .NET and Aspose.Imaging for .NET will be used.
Alternatively, get the offline MSI installer or DLLs in a ZIP file from downloads .
Convert CGM File to DXF in a Single File via C#
Using the API, you can also convert CGM file to DXF to a single image file. In order to convert all pages, you can first render your CGM document to one TIFF file and after that you can export TIFF file to DXF. You can open the input file using Document class and create Resolution, TiffSettings, & TIFF device objects. You can get a single TIFF image using Process method of TiffDevice class. Finally, you can load TIFF file using Image class and save it to DXF format using Save method.
Convert CGM to DXF With Watermark via C#
Using the API, you can also convert CGM file to DXF with watermark in your DXF document. In order to add a watermark, you can first render your CGM document to JPEG and add a watermark in it. To demonstrate the operation, you can load your converted JPEG image, add transformations using an object of Matrix class and draw a string as the watermark on the image surface using the Graphics class’ DrawString method. After adding the watermark in it, you can save the JPEG as DXF format. Below is a code example that demonstrates how to add a diagonal watermark to your document.
Convert & Rotate CGM File to DXF via C#
Using the API, you can also rotate the output DXF image as per your needs. The Image.RotateFlip method can be used to rotate the image by 90/180/270-degrees and flip the image horizontally or vertically. You can specify the type of rotation and flip to apply to the image. In order to rotate and flip the image you can load the converted JPEG image using the factory method exposed by Image class and call the Image.RotateFlip method while specifying the appropriate RotateFlipType .

What is CGM File Format?
A Computer Graphics Metafile (CGM) is a file format for 2D vector graphics, raster graphics, and text, and is defined by ISO/IEC 8632. CGM files may contain 2D vector graphics, raster graphics, and text. All aspects of the graphics can be stored, including color palettes, line widths, fonts, and text size and location. CGM files usually have a .cgm filename extension, but they may also use .cgi, .cgmz, or .cgz.CGM is a platform-independent file format, meaning that it can be used on any type of computer, regardless of the operating system. CGM files are often used for vector graphics because they can be scaled without losing quality. CGM files are also used for technical drawings, such as engineering diagrams, because they can be accurately printed at any size.CGM files can be created by a wide variety of software programs, including vector graphics editors, CAD programs, and word processors. Many programs that can export to CGM format also support importing CGM files.
What is DXF File Format?
The Autodesk Drawing Exchange Format (DXF) is a widely used file format developed by Autodesk for facilitating data interoperability between Autodesk software and other programs. DXF serves as a structured file format that stores drawing information as a collection of vector entities. These entities encompass various geometric shapes, such as points, lines, arcs, circles, polygons, and text. Additionally, DXF files also have the capability to support raster images.
First introduced in December 1982 as part of AutoCAD 1.0, DXF has undergone several revisions and extensions over the years. The latest revision is DXF R2018, which was introduced alongside AutoCAD 2018.
DXF files are stored as ASCII text files, allowing them to be viewed and edited in any text editor. However, dedicated programs designed for working with DXF files, such as AutoCAD, offer more comprehensive features for viewing and editing. When opened in a text editor, a DXF file is typically divided into three sections: the header, the drawing body, and the trailer. The header contains general information about the drawing, including its title, author, and creation date. The drawing body comprises the actual vector entities that constitute the drawing, while the trailer provides concluding information, such as the total number of entities in the file.
DXF files are conventionally saved with the .dxf file extension, and their versatility and widespread adoption have made them a standard for exchanging and sharing drawing data across various CAD and design applications.
