How to Create GIF From Images in C#

This tutorial describes how to create a GIF from images in C#. You’ll learn to configure your environment, load images, and generate an animated GIF file, all while maintaining a straightforward approach.

Benefits of Creating GIFs from Images

  1. Visual Appeal:
    • Animated GIFs enhance content engagement.
  2. Easy Sharing:
    • GIFs are widely supported and easy to share across platforms.
  3. Lightweight Animation:
    • GIFs are smaller than video files, making them more suitable for quick-loading web content.

Prerequisites: Preparing the Environment

  1. Set up Visual Studio or any compatible .NET IDE.
  2. Install Aspose.Imaging via NuGet Package Manager.

Step-by-Step Guide to Create GIF From Images

Step 1: Configure the Project

Set up your project to utilize Aspose.Imaging for GIF creation.

Install-Package Aspose.Imaging

Step 2: Load Raster Images

Create a list of raster images from the specified directory containing image files.

var rasterImages = LoadRasterImages("AnimationImages/").ToArray();

Step 3: Create the GIF Image

Initialize the GIF image using the first image loaded into the list.

using (var gifImage = new GifImage(new GifFrameBlock(rasterImages[0])))
{
    // Further processing steps follow here
}

Step 4: Add Remaining Images

Iterate through the rest of the images in the list and add them to the GIF image.

for (var imageIndex = 1; imageIndex < rasterImages.Length; imageIndex++)
{
    gifImage.AddPage(rasterImages[imageIndex]);
}

Step 5: Save the GIF Image

After adding all images, save the GIF to disk.

gifImage.Save("Multipage.gif");

Complete Code Example to Create GIF From Images

Here’s the full example that demonstrates creating a GIF from images:

// Load the list of raster images from the directory
var rasterImages = LoadRasterImages("AnimationImages/").ToArray();

// Create a GIF image from the first raster image
using (var gifImage = new GifImage(new GifFrameBlock(rasterImages[0])))
{
    // Add the remaining images to the GIF
    for (var imageIndex = 1; imageIndex < rasterImages.Length; imageIndex++)
    {
        gifImage.AddPage(rasterImages[imageIndex]);
    }

    // Save the GIF image on the disk
    gifImage.Save("Multipage.gif");
}

Console.WriteLine("Done");


// Function to load images from the specified directory
private static IEnumerable<RasterImage> LoadRasterImages(string directory)
{
    foreach (var imagePath in Directory.GetFiles(directory))
    {
        yield return (RasterImage)Image.Load(imagePath);
    }
}

Conclusion

This tutorial has shown the process of creating a GIF from images in C# using Aspose.Imaging. By following these steps, you can efficiently generate animated GIFs tailored to your requirements. For additional image manipulation capabilities, consider exploring other features like resizing or rotating images.
