Change background in GIF via C#

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

How to change background in GIF Files Using C#

Frequently, achieving the ideal image requires changing the background. To attain the desired GIF 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 GIF 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.

    GIF What is GIF File Format

    A GIF or Graphical Interchange Format is a type of highly compressed image. Owned by Unisys, GIF uses the LZW compression algorithm that does not degrade the image quality. For each image GIF typically allow up to 8 bits per pixel and up to 256 colours are allowed across the image. In contrast to a JPEG image, which can display up to 16 million colours and fairly touches the limits of the human eye. Back when the internet emerged, GIFs remained the best choice because they required low bandwidth and compatible for the graphics that consume solid areas of colour. An animated GIF combines numerous images or frames into a single file and displays them in a sequence to generate an animated clip or a short video. The colour limitations are up to 256 for each frame and are likely to be the least suitable for reproducing other images and photographs with colour gradient.
