Add Transparent Object in Java XPS

Introduction

If you’re looking to enhance the visual appeal of your Java XPS documents by adding transparent objects, Aspose.Page for Java is the solution for you. In this step-by-step guide, we’ll walk you through the process of incorporating transparent objects into your XPS document. By the end of this tutorial, you’ll be able to create stunning documents with aesthetically pleasing transparency effects.

Prerequisites

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

  • Java Development Environment: Ensure that you have a Java development environment set up on your system.
  • Aspose.Page for Java Library: Download and install the Aspose.Page for Java library. You can find the library and its documentation here.

Import Packages

In your Java project, import the necessary Aspose.Page packages to get started with adding transparent objects. Include the following lines at the beginning of your Java file:

import com.aspose.xps.XpsDocument;
import com.aspose.xps.XpsPath;
import java.awt.Color;

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

Step 1: Initialize the Document

// The path to the documents directory.
String dataDir = "Your Document Directory";
// Initialize document
XpsDocument doc = new XpsDocument();

Start by setting up your document and specifying the directory where your XPS document will be saved.

Step 2: Create Transparent Objects

// Just to demonstrate transparency
doc.addPath(doc.createPathGeometry("M120,0 H400 v1000 H120")).setFill(doc.createSolidColorBrush(Color.GRAY));
doc.addPath(doc.createPathGeometry("M300,120 h600 V420 h-600")).setFill(doc.createSolidColorBrush(Color.GRAY));

Here, we create two transparent paths to demonstrate the transparency effect using the specified geometries and colors.

Step 3: Add Filled Paths

// Create path with closed rectangle geometry
XpsPath path1 = doc.createPath(doc.createPathGeometry("M20,20 h200 v200 h-200 z"));
// Set blue solid brush to fill path1
path1.setFill(doc.createSolidColorBrush(Color.BLUE));
// Add it to the current page
XpsPath path2 = doc.add(path1);

In this step, we create a path with a closed rectangle geometry, fill it with a blue solid brush, and add it to the current page.

Step 4: Manipulate Transparency

// path1 and path2 are the same as long as path1 hasn't been placed inside any other element
path2.setFill(doc.createSolidColorBrush(Color.GREEN));
// Now add path2 once again. Now path2 has a parent, so path3 won't be the same as path2.
XpsPath path3 = doc.add(path2);
path3.setRenderTransform(doc.createMatrix(1, 0, 0, 1, 0, 300));
path3.setFill(doc.createSolidColorBrush(Color.RED));

Here, we demonstrate the impact of transparency when paths have a parent element. Manipulate the transparency and color of the paths accordingly.

Step 5: Duplicate and Modify Paths

// Create new path4 with path2's geometry
XpsPath path4 = doc.addPath(path2.getData());
path4.setRenderTransform(doc.createMatrix(1, 0, 0, 1, 300, 0));
path4.setFill(doc.createSolidColorBrush(Color.BLUE));
// Add path4 once again.
XpsPath path5 = doc.add(path4);
path5.setRenderTransform(path5.getRenderTransform().deepClone());
path5.getRenderTransform().translate(0, 300);
path5.getFill().setOpacity(0.8f);

Duplicate paths and modify their properties to create variations in transparency and color, showcasing the versatility of Aspose.Page.

Step 6: Save the Document

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

Finally, save the document with the added transparent objects.

Conclusion

Congratulations! You’ve successfully learned how to add transparent objects to your Java XPS documents using Aspose.Page. Experiment with different geometries, colors, and transparency levels to create visually stunning documents.
