Change background in WMF via C#

Build your own .NET apps to Change background in WMF files using server-side APIs.

How to change background in WMF Files Using C#

Frequently, achieving the ideal image requires changing the background. To attain the desired WMF format image effect, foreground objects must be isolated from the rest of the picture. Automatic object detection is possible if the background is uniform. If the photo’s background is uneven or object separation is challenging, pre-marking the image is recommended. This involves identifying rectangular regions within the photo where intended objects reside and specifying their types. This can be done manually or automatically through the Cloud API’s object recognition feature. Following object selection and original background removal, a new background can be applied or transparency can be implemented. In order to change background in WMF files, we’ll use Aspose.Imaging for .NET API which is a feature-rich, powerful and easy to use image manipulation and conversion API for C# platform. Open NuGet package manager, search for Aspose.Imaging and install. You may also use the following command from the Package Manager Console.

  • About Aspose.Imaging for .NET API

    Aspose.Imaging API is an image processing solution to create, modify, draw or convert images (photos) within applications. It offers: cross-platform Image processing, including but not limited to conversions between various image formats (including uniform multi-page or multi-frame image processing), modifications such as drawing, working with graphic primitives, transformations (resize, crop, flip&rotate, binarization, grayscale, adjust), advanced image manipulation features (filtering, dithering, masking, deskewing), and memory optimization strategies. It’s a standalone library and does not depend on any software for image operations. One can easily add high-performance image conversion features with native APIs within projects. These are 100% private on-premise APIs and images are processed at your servers.

    WMF What is WMF File Format

    Files with WMF extension represent Microsoft Windows Metafile (WMF) for storing vector as well as bitmap-format images data. To be more accurate, WMF belongs to the vector file format category of Graphics file formats that is device independent. Windows Graphical Device Interface (GDI) uses the functions stored in a WMF file to display an image on the screen. A more enhanced version of WMF, known as Enhanced Meta Files (EMF), was published later that makes the format more feature rich. Practically, WMF are similar to SVG.
