Add a Signature to an Image with Aspose.PSD for Java

Introduction

In the vast world of Java development, incorporating signatures into images has become a common requirement. Aspose.PSD for Java emerges as a powerful tool, providing developers with seamless solutions for manipulating images, including the addition of signatures. In this tutorial, we will explore step by step how to add a signature to an image using Aspose.PSD for Java.

Prerequisites

Before diving into the tutorial, ensure that you have the following prerequisites in place:

• Java Development Kit (JDK) installed on your system.
• Aspose.PSD for Java library downloaded and set up in your Java project.

Import Packages

To get started, import the necessary packages into your Java class:

import com.aspose.psd.Graphics;
import static com.aspose.psd.GraphicsUnit.Point;
import com.aspose.psd.Image;
import com.aspose.psd.Point;

import com.aspose.psd.imageoptions.PngOptions;

Step 1: Load Primary and Secondary Images

Create instances of the Image class and load both the primary and secondary images:

//ExStart:LoadImages
String dataDir = "Your Document Directory";

// Load the primary image
Image canvas = Image.load(dataDir + "layers.psd");

// Load the secondary image containing the signature graphics
Image signature = Image.load(dataDir + "sample.psd");
//ExEnd:LoadImages

Step 2: Initialize Graphics Class

Create an instance of the Graphics class and initialize it using the object of the primary image:

//ExStart:InitializeGraphics
Graphics graphics = new Graphics(canvas);
//ExEnd:InitializeGraphics

Step 3: Add Signature to Image

Use the DrawImage method to add the signature to the primary image. Adjust the location as needed. In this example, we attempt to place the secondary image at the right bottom of the primary image:

//ExStart:AddSignatureToImage
graphics.drawImage(signature, new Point(canvas.getHeight() - signature.getHeight(), canvas.getWidth() - signature.getWidth()));
canvas.save(dataDir + "AddSignatureToImage_out.png", new PngOptions());
//ExEnd:AddSignatureToImage

Repeat these steps in your Java application to seamlessly add a signature to an image using Aspose.PSD.
