This tutorial focuses on how to convert image to grayscale in C#. It encompasses the environment settings, the stepwise process, and a sample code snippet to convert image to grayscale in C#. You can follow this guide to convert several image formats like JPG, PNG, BMP, etc.

Steps to Convert Image to Grayscale in C#

1. Prepare the IDE by installing Aspose.Imaging for .NET with the NuGet package manager to convert the color image to Grayscale
2. Read the source color image with the Image class
3. Cast the image to a RasterCachedImage class object
4. Transform the input image to its grayscale version
5. Write the grayscale image using the Save method

These steps summarize the sequence to convert picture to black and white in C#. Firstly, read the source color image and cache it. Consequently, change the image’s color space to its grayscale version and export the output image.
