Convert CGM file to Image via C#
Export CGM to Images within .NET applications without using Adobe® Acrobat Reader or any other third party applications
With Aspose.Total for .NET, you can easily export CGM files to various image formats within any .NET application in just two simple steps. First, using Aspose.PDF for .NET, you can export CGM to JPEG format. Afterward, by utilizing Aspose.Imaging for .NET Image Processing API, you can convert the JPEG image to a wide range of image formats.
By combining the power of Aspose.PDF for .NET and Aspose.Imaging for .NET, you can seamlessly convert CGM files to popular image formats like JPEG, PNG, TIFF, GIF, BMP, and more. This versatility enables you to integrate image conversion capabilities into your .NET applications, catering to diverse requirements and preferences.
Convert CGM file to Image 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 JPEG2000 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 Image in a Single File via C#
Using the API, you can also convert CGM file to Image 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 Image. 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 JPEG2000 format using Save method.
Convert CGM to Image With Watermark via C#
Using the API, you can also convert CGM file to Image with watermark in your Image 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 JPEG2000 format. Below is a code example that demonstrates how to add a diagonal watermark to your document.
Convert & Rotate CGM File to Image via C#
Using the API, you can also rotate the output Image 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 IMAGE File Format?
Image files are computer files specifically designed to store digital images. These files come in various types, such as bitmap, JPEG, GIF, and TIFF, each with its own characteristics and applications. The file type determines the software program used to open and view the image.
Bitmap files, also known as raster images, consist of a grid of individual pixels, each assigned a specific color value. When viewed from a distance, these pixels blend together to create a cohesive image. Bitmap files tend to be large in size due to the amount of detailed information they contain.
JPEG files are compressed image files that utilize a mathematical algorithm to reduce file size while preserving image quality. This makes them ideal for storing and sharing photos online, as they can be efficiently compressed without significant loss of quality.
GIF files, another type of compressed image format, employ a different algorithm than JPEG. GIF files can store more colors and produce better image quality, but they are limited to a maximum of 256 colors, making them less suitable for storing high-quality images. GIF files are commonly used for animated images and simple graphics.
TIFF files, on the other hand, are uncompressed image files. They do not utilize any compression algorithms, resulting in larger file sizes compared to other image formats. TIFF files are typically used for storing high-quality images that require editing or printing.
Each image file format serves different purposes and is suited for specific use cases. Bitmap files are detailed but large, JPEG files offer efficient compression, GIF files are suitable for animations and simple graphics, and TIFF files provide uncompressed, high-quality images.
