Convert PDF file to WMF via C#
Export PDF to WMF within .NET applications without using Adobe® Acrobat Reader or any other third party applications
Aspose.Total for .NET is a comprehensive suite of .NET components that enables developers to easily export PDF to WMF image within any .NET applications. This suite includes Aspose.PDF for .NET and Aspose.Imaging for .NET, which are two powerful components that can be used to export PDF to WMF image.
The process of exporting PDF to WMF image can be done in two simple steps. First, Aspose.PDF for .NET can be used to export PDF to JPEG. This component is a powerful PDF manipulation API that enables developers to create, read, edit, and convert PDF documents without any external dependencies. It also provides a wide range of features such as document manipulation, text extraction, image extraction, and more.
Once the PDF is exported to JPEG, Aspose.Imaging for .NET can be used to convert JPEG to WMF. This component is a powerful image processing API that enables developers to create, edit, and convert images in various formats. It also provides a wide range of features such as image manipulation, image conversion, image resizing, and more.
By using Aspose.Total for .NET, developers can easily export PDF to WMF image within any .NET applications. This suite provides a comprehensive set of components that can be used to create, read, edit, and convert PDF documents as well as manipulate and convert images in various formats. With this suite, developers can easily export PDF to WMF image in two simple steps.
Convert PDF file to WMF via .NET
- Open PDF file using Document class
- Initialize JpegDevice class object and render PDF to JPEG by using Process method
- Load JPEG file by using Image class
- Save the document to WMF format using Save method
Get Started with .NET File Automation APIs
Install from command line as nuget install Aspose.Total or install directly from Package Manager Console of Visual Studio.
Alternatively, get the offline MSI installer or DLLs in a ZIP file from downloads .
Convert PDF File to WMF in a Single File via C#
Using the API, you can also convert PDF file to WMF to a single image file. In order to convert all pages, you can first render your PDF document to one TIFF file and after that you can export TIFF file to WMF. 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 WMF format using Save method.
Convert PDF to WMF With Watermark via C#
Using the API, you can also convert PDF file to WMF with watermark in your WMF document. In order to add a watermark, you can first render your PDF 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 WMF format. Below is a code example that demonstrates how to add a diagonal watermark to your document.
Convert & Rotate PDF File to WMF via C#
Using the API, you can also rotate the output WMF 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 PDF File Format?
PDF, or Portable Document Format, is a file format designed for presenting documents in a manner that remains consistent across various software applications, hardware devices, and operating systems. Each PDF file contains a comprehensive description of a fixed-layout document, encompassing text, fonts, graphics, and other necessary information for accurate display. Initially developed by Adobe Systems in the early 1990s, PDF served as a means to share computer documents while preserving text formatting and inline images.
PDF files are typically generated using software like Adobe Acrobat or similar PDF creation tools. Presently, PDF has become an open standard governed by the International Organization for Standardization (ISO). This standardization ensures compatibility and interoperability across different platforms and systems. To view PDF files, users can utilize free software such as Adobe Reader or other PDF viewers available.
One of the significant advantages of PDF is its platform independence, allowing seamless viewing and printing on a wide range of devices and operating systems. Regardless of the hardware or software used, the document’s layout and content will remain intact. This universal accessibility has contributed to the popularity of PDF as a preferred format for sharing and distributing documents across diverse platforms and systems.
PDF’s capability to encapsulate a complete document, including text, fonts, graphics, and formatting, makes it a reliable choice for various applications. Whether it’s sharing important reports, publishing e-books, distributing forms, or delivering professional presentations, PDF ensures consistent document rendering and reliable preservation of content across different environments.
What is WMF File Format?
Windows Metafile (WMF) is a graphics file format commonly used on Microsoft Windows systems. It is typically created by vector graphic editors such as Adobe Illustrator or Microsoft Office Visio. WMF files are designed to be displayed on screens and printed on printers. The format is based on the Windows Graphics Device Interface (GDI) and utilizes a device-independent coordinate system.
WMF files can contain both vector graphics and bitmap images. Vector graphics are defined using mathematical formulas that represent lines, curves, and shapes, allowing for scalability without loss of quality. Bitmap images, on the other hand, consist of pixels arranged in a grid and are suitable for representing complex visual details.
Various programs, including Microsoft Word, Microsoft PowerPoint, and Adobe Photoshop, can open and work with WMF files. These programs provide features for editing, resizing, and manipulating the graphics within the WMF files.
It’s important to note that WMF is an older file format, and its usage has decreased over time in favor of more modern formats such as SVG (Scalable Vector Graphics) and PNG (Portable Network Graphics). However, WMF files are still supported by many applications and can be converted to other formats if needed.
