Set Opacity Mask in Java XPS

Introduction

Welcome to our comprehensive guide on setting opacity masks in Java XPS using Aspose.Page. In this tutorial, we’ll walk you through the process of creating an XPS document, adding a canvas, and applying an opacity mask to a rectangle using the powerful features of Aspose.Page for Java.

Prerequisites

Before diving into this tutorial, make sure you have the following:

  • A basic understanding of Java programming.
  • Aspose.Page for Java library installed. You can download it here.
  • A valid license for Aspose.Page. If you don’t have one, you can obtain a temporary license here.
  • A development environment set up to run Java applications.

Import Packages

Start by importing the necessary packages into your Java project. Ensure that you have the Aspose.Page library properly integrated. Below is a snippet to guide you:

import com.aspose.xps.XpsCanvas;
import com.aspose.xps.XpsDocument;
import com.aspose.xps.XpsImageBrush;
import com.aspose.xps.XpsPath;
import com.aspose.xps.XpsTileMode;
import java.awt.geom.Rectangle2D;

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

Step 1: Create a New XPS Document

// Create a new XPS document
XpsDocument doc = new XpsDocument();

Step 2: Add a Canvas

// New canvas
XpsCanvas canvas = doc.addCanvas();

Step 3: Add a Rectangle with Opacity Mask

// Rectangle in the middle left with opacity masked by ImageBrush
XpsPath path = canvas.addPath(doc.createPathGeometry("M 10,180 L 228,180 228,285 10,285"));
path.setFill(doc.createSolidColorBrush(doc.createColor(1.0f, 0.0f, 0.0f)));

Step 4: Set Opacity Mask with ImageBrush

path.setOpacityMask(doc.createImageBrush(dataDir +  "R08SY_NN.tif", 
                    new Rectangle2D.Float(0f, 0f, 128f, 192f), new Rectangle2D.Float(0f, 0f, 64f, 96f)));
((XpsImageBrush)path.getOpacityMask()).setTileMode(XpsTileMode.Tile);

Step 5: Save the Resultant XPS Document

// Save resultant XPS document
doc.save(dataDir + "OpacityMask_out.xps");

Follow these steps carefully to incorporate opacity masks into your Java XPS document using Aspose.Page.
