How to Merge Images Programmatically in C#

Follow this step-by-step guide to implement the Image Merger Plugin for merging images either horizontally or vertically.

Code Example

using Aspose.Imaging;
using Aspose.Imaging.ImageOptions;
using Aspose.Imaging.Sources;
using System;
using System.Collections.Generic;
using System.IO;

string templatesFolder = @"C:\\Users\\USER\\Downloads\\templates\\";

void MergeImagesExample()
{
    Metered license = new Metered();
    license.SetMeteredKey("<your-public-key>", "<your-private-key>");

    var images = new List<Image>();
    string[] fileNames = { "template.png", "template.jpg", "template.bmp" };

    int totalWidth = 0, totalHeight = 0, maxWidth = 0, maxHeight = 0;

    foreach (var file in fileNames)
    {
        var image = Image.Load(Path.Combine(templatesFolder, file));
        images.Add(image);
        totalWidth += image.Width;
        totalHeight += image.Height;
        maxWidth = Math.Max(maxWidth, image.Width);
        maxHeight = Math.Max(maxHeight, image.Height);
    }

    MergeImages(images, MergeDirection.Horizontal, totalWidth, maxHeight, 
        Path.Combine(templatesFolder, "merged_horizontal.jpg"));

    MergeImages(images, MergeDirection.Vertical, totalHeight, maxWidth, 
        Path.Combine(templatesFolder, "merged_vertical.jpg"));

    images.ForEach(image => image.Dispose());
}

void MergeImages(List<Image> images, MergeDirection direction, int totalSize, int maxSize, string outputPath)
{
    int width = direction == MergeDirection.Horizontal ? totalSize : maxSize;
    int height = direction == MergeDirection.Vertical ? totalSize : maxSize;

    using (var image = Image.Create(new PngOptions { Source = new StreamSource(new MemoryStream()) }, width, height))
    {
        var graphics = new Graphics(image);
        float x = 0, y = 0;

        foreach (var img in images)
        {
            graphics.DrawImage(img, new RectangleF(x, y, img.Width, img.Height));
            if (direction == MergeDirection.Horizontal) x += img.Width;
            if (direction == MergeDirection.Vertical) y += img.Height;
        }

        image.Save(outputPath);
    }
}

enum MergeDirection
{
    Horizontal,
    Vertical
}

Key Steps in the Code

  • Load Images: Load multiple images into a list.
  • Calculate Dimensions: Calculate the total dimensions based on the merge direction.
  • Draw Images: Use the Graphics.DrawImage method to arrange the images either horizontally or vertically.
  • Save the Output: Save the merged image in the desired format.
