Add Vertical Gradient in Java XPS

Introduction

In this tutorial, we will explore how to add a vertical gradient in Java XPS using Aspose.Page for Java. Adding gradients to your XPS documents can enhance the visual appeal of your content, making it more engaging and aesthetically pleasing.

Prerequisites

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

  • A working Java development environment.
  • Aspose.Page for Java library. You can download it from here.
  • A basic understanding of Java programming.

Import Packages

Start by importing the necessary packages for your Java project. Ensure that you have included the Aspose.Page for Java library in your project dependencies.

import com.aspose.xps.XpsDocument;
import com.aspose.xps.XpsGradientBrush;
import com.aspose.xps.XpsGradientStop;
import com.aspose.xps.XpsPath;
import java.awt.geom.Point2D;
import java.util.LinkedList;
import java.util.List;
// The path to the documents directory.
String dataDir = "Your Document Directory";
        
// Import Aspose.Page for Java

Step 1: Initialize the Document

Begin by initializing the XPS document. This sets the foundation for adding elements such as paths and gradients to your document.

// Initialize document
XpsDocument doc = new XpsDocument();

Step 2: Create a Path with Vertical Gradient

Now, let’s create a path with a vertical gradient. This involves defining the path geometry and specifying the gradient stops.

// Create a path with geometry
XpsPath path = doc.addPath(doc.createPathGeometry("M 30,20 l 258.24,0 0,56.64 -258.24,0 Z"));
// Define vertical gradient stops
List<XpsGradientStop> stops = new LinkedList<XpsGradientStop>();
stops.add(doc.createGradientStop(doc.createColor(253, 255, 12, 0), 0f));
stops.add(doc.createGradientStop(doc.createColor(252, 255, 154, 0), 0.359375f));
stops.add(doc.createGradientStop(doc.createColor(252, 255, 56, 0), 0.424805f));
stops.add(doc.createGradientStop(doc.createColor(253, 255, 229, 0), 0.879883f));
stops.add(doc.createGradientStop(doc.createColor(252, 255, 255, 234), 1f));
// Apply the vertical gradient to the path
path.setFill(doc.createLinearGradientBrush(new Point2D.Float(10f, 110f), new Point2D.Float(10f, 200f)));
((XpsGradientBrush)path.getFill()).getGradientStops().addAll(stops);

Step 3: Save the Document

Finally, save the XPS document with the added vertical gradient to your desired directory.

// Save the document
doc.save(dataDir + "VerticalGradient.xps");

Congratulations! You have successfully added a vertical gradient to your Java XPS document using Aspose.Page.

Conclusion

Enhancing your XPS documents with gradients can significantly improve their visual appeal. Aspose.Page for Java simplifies this process, allowing you to create stunning documents with ease.
