Combining Images - Step by Step

To combine images, you can follow these simple steps:

Step 1: Create a New Project

Create a new project or open an existing one in Visual Studio.

Step 2: Set the Data Directory

Define the data directory where your image files are located. Replace "Your Document Directory" with the actual path to your image files:

string dataDir = "Your Document Directory";

Step 3: Initialize Image Options

Create an instance of JpegOptions to set various properties:

JpegOptions imageOptions = new JpegOptions();

Step 4: Specify the Output Image

Create an instance of FileCreateSource and assign it to the Source property of your imageOptions. This step defines the name and format of the output image:

imageOptions.Source = new FileCreateSource(dataDir + "Two_images_result_out.bmp", false);

Step 5: Create a New Image

Create an instance of Image and define the canvas size. The following code creates an image with a canvas size of 600x600:

using (var image = Image.Create(imageOptions, 600, 600))

Step 6: Add Images to the Canvas

Use the Graphics class to add and position the images on the canvas. The DrawImage method allows you to specify the image file, position, and dimensions for each image you want to combine:

var graphics = new Graphics(image);
graphics.Clear(Color.White); // Clear the canvas with a white background.
graphics.DrawImage(Image.Load(dataDir + "sample_1.bmp"), 0, 0, 600, 300); // First image.
graphics.DrawImage(Image.Load(dataDir + "File1.bmp"), 0, 300, 600, 300);    // Second image.

Step 7: Save the Combined Image

Finally, save the combined image:

image.Save();
