Add Gradient Effects in Aspose.PSD for Java

Introduction

Welcome to the tutorial on adding gradient effects in Aspose.PSD for Java! If you’re looking to enhance your images with stunning gradient overlays, you’re in the right place. In this guide, we’ll walk you through the process using Aspose.PSD, a powerful Java library for image processing.

Prerequisites

Before we dive into the tutorial, make sure you have the following prerequisites in place:

Aspose.PSD for Java Library: Ensure you have downloaded and installed the Aspose.PSD for Java library. You can find the library and its documentation here .
Java Development Environment: Set up a Java development environment on your machine.

Now that you have everything set up, let’s proceed with the step-by-step guide.

Import Packages

Start by importing the necessary packages in your Java project. This ensures that you have access to the Aspose.PSD functionality. Here’s a basic example:

import com.aspose.psd.Color;
import com.aspose.psd.Image;


import com.aspose.psd.fileformats.psd.PsdImage;
import com.aspose.psd.fileformats.psd.layers.BlendMode;
import com.aspose.psd.fileformats.psd.layers.IGradientColorPoint;
import com.aspose.psd.fileformats.psd.layers.fillsettings.*;
import com.aspose.psd.fileformats.psd.layers.layereffects.GradientOverlayEffect;
import com.aspose.psd.imageloadoptions.PsdLoadOptions;

Now, let’s break down the example into multiple steps.

Step 1: Load PSD File and Access Gradient Overlay


// Gradient overlay effect. Example
String sourceFileName = dataDir + "GradientOverlay.psd";
String exportPath = dataDir + "GradientOverlayChanged.psd";
PsdLoadOptions loadOptions = new PsdLoadOptions();
loadOptions.setLoadEffectsResource(true);
PsdImage im = (PsdImage)Image.load(sourceFileName, loadOptions);
GradientOverlayEffect gradientOverlay = (GradientOverlayEffect)im.getLayers()[1].getBlendingOptions().getEffects()[0];

In this step, we load a PSD file and access the gradient overlay effect.

Step 2: Verify Initial Settings

// Verify initial settings
Assert.areEqual(BlendMode.Normal, gradientOverlay.getBlendMode());
Assert.areEqual(255, gradientOverlay.getOpacity());
Assert.areEqual(true, gradientOverlay.isVisible());
// ... (additional verifications)

Ensure the initial settings of the gradient overlay match your requirements.

Step 3: Modify Gradient Settings

// Modify gradient settings
settings.setColor(Color.getGreen());
gradientOverlay.setOpacity((byte)193);
gradientOverlay.setBlendMode(BlendMode.Lighten);
// ... (additional modifications)

Customize the gradient settings according to your preferences.

Step 4: Save the Edited Image

// Save the edited image
im.save(exportPath);

Save the image after applying the gradient effects.

Step 5: Verify Changes

// Verify changes after editing
PsdImage img = (PsdImage)Image.load(sourceFileName, loadOptions);

GradientOverlayEffect gradientOverlayEffect = (GradientOverlayEffect)img.getLayers()[1].getBlendingOptions().getEffects()[0];
// ... (additional verifications)

Ensure the changes are successfully applied to the image.

Repeat these steps for any further modifications or additional effects you want to add.

Conclusion

Congratulations! You’ve successfully learned how to add gradient effects to your images using Aspose.PSD for Java. Experiment with different settings to achieve the desired visual impact.
