Add Pattern Effects in Aspose.PSD for Java

Introduction

In the world of Java development, enhancing image patterns is a common task, and Aspose.PSD for Java provides a robust solution for this. This tutorial will guide you through the process of adding pattern effects using Aspose.PSD, ensuring that your images stand out with unique overlays and enhancements.

Prerequisites

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

• Java Development Kit (JDK) installed on your system.
• Aspose.PSD for Java library downloaded and added to your project. You can download it from the Aspose.PSD website.

Import Packages

In your Java project, import the necessary packages for working with Aspose.PSD. Include the following code at the beginning of your Java class:

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


import com.aspose.psd.fileformats.psd.PsdImage;
import com.aspose.psd.fileformats.psd.layers.BlendMode;
import com.aspose.psd.fileformats.psd.layers.fillsettings.FillType;
import com.aspose.psd.fileformats.psd.layers.fillsettings.PatternFillSettings;
import com.aspose.psd.fileformats.psd.layers.layereffects.PatternOverlayEffect;
import com.aspose.psd.fileformats.psd.layers.layerresources.PattResource;
import com.aspose.psd.imageloadoptions.PsdLoadOptions;

import java.util.UUID;

Step 1: Load the Image

// Load the PSD image
String sourceFileName = "YourImagePath/PatternOverlay.psd";
String exportPath = "YourExportPath/PatternOverlayChanged.psd";

PsdLoadOptions loadOptions = new PsdLoadOptions();
loadOptions.setLoadEffectsResource(true);

PsdImage im = (PsdImage)Image.load(sourceFileName, loadOptions);

Ensure to replace “YourImagePath” and “YourExportPath” with the actual paths in your project.

Step 2: Extract Pattern Overlay Information

// Extract information about the pattern overlay
PatternOverlayEffect patternOverlay = (PatternOverlayEffect)im.getLayers()[1].getBlendingOptions().getEffects()[0];

Step 3: Modify Pattern Overlay Settings

// Modify pattern overlay settings
PatternFillSettings settings = patternOverlay.getSettings();
settings.setColor(Color.getGreen());
patternOverlay.setOpacity((byte)193);
patternOverlay.setBlendMode(BlendMode.Difference);
settings.setHorizontalOffset(15);
settings.setVerticalOffset(11);

Step 4: Edit the Pattern Data

// Edit the pattern data
PattResource resource;
UUID guid = UUID.randomUUID();
String newPatternName = "$$/Presets/Patterns/Pattern=Some new pattern name\0";

for (int i = 0; i < im.getGlobalLayerResources().length; i++) {
    if (im.getGlobalLayerResources()[i] instanceof PattResource) {
        resource = (PattResource)im.getGlobalLayerResources()[i];
        resource.setPatternId(guid.toString());
        resource.setName(newPatternName);
        resource.setPattern(new int[]{Color.getAqua().toArgb(), Color.getRed().toArgb(),
                        Color.getRed().toArgb(), Color.getAqua().toArgb(),
                        Color.getAqua().toArgb(), Color.getWhite().toArgb(),
                        Color.getWhite().toArgb(), Color.getAqua().toArgb()}, new Rectangle(0, 0, 4, 2));
    }
}

Step 5: Save the Edited Image

// Save the edited image
settings.setPatternName(newPatternName);
settings.setPatternId(guid.toString() + "\0");
im.save(exportPath);

Step 6: Verify the Changes

// Verify the changes in the edited file
PsdImage img = (PsdImage)Image.load(sourceFileName, loadOptions);
PatternOverlayEffect patternOverlayEffect = (PatternOverlayEffect)img.getLayers()[1].getBlendingOptions().getEffects()[0];

// Add assertions to ensure the changes have been applied successfully

Conclusion

Congratulations! You’ve successfully learned how to add pattern effects using Aspose.PSD for Java. This powerful library allows you to create visually appealing images with customized patterns, providing endless possibilities for your Java-based projects.
