Remove background from PNG via C#

Build your own .NET apps to Remove background from PNG files using server-side APIs.

How to remove background in PNG Files Using C#

Removing the background from an image involves isolating foreground objects, a task that requires object recognizing. Multiple approaches exist to identify objects within a photo in PNG format. For simple images featuring a uniform color background, an automatic method suffices. However, for photos with multiple or partially merged figures, pre-marking objects becomes necessary. This involves specifying rectangular regions and object types for removal. In intricate cases, the Cloud API enables automatic object detection. The Cloud API provides a cloud application capable of recognizing objects within photos, leveraging the resulting contours for background removal. Post-removal, edges left behind by figures can be smoothed to enhance image quality. In order to remove background in PNG 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.
