Add Hatch Pattern in Java PostScript

Introduction

In the world of Java programming, enhancing visual elements is a common requirement for developers. One intriguing visual enhancement is the addition of hatch patterns to PostScript documents. This tutorial will guide you through the process of adding hatch patterns using Aspose.Page for Java.

Prerequisites

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

Java Development Environment: Ensure you have a Java development environment ready.
Aspose.Page for Java Library: Download and install the Aspose.Page for Java library. You can find the necessary files here.

Import Packages

To get started, import the required packages into your Java project. Use the following code snippet:

import java.awt.BasicStroke;
import java.awt.Color;
import java.awt.Font;
import java.awt.TexturePaint;
import java.awt.geom.Rectangle2D;
import java.io.FileOutputStream;
import com.aspose.eps.HatchPaintLibrary;
import com.aspose.eps.HatchStyle;
import com.aspose.eps.PsDocument;
import com.aspose.eps.device.PsSaveOptions;

Step 1: Set Up Initial Parameters

// The path to the documents directory.
String dataDir = "Your Document Directory";
// Create output stream for PostScript document
FileOutputStream outPsStream = new FileOutputStream(dataDir + "AddHatchPattern_outPS.ps");
// Create save options with A4 size
PsSaveOptions options = new PsSaveOptions();
// Create new PS Document with the page opened
PsDocument document = new PsDocument(outPsStream, options, false);
int x0 = 20;
int y0 = 100;
int squareSide = 32;
int width = 500;
int sumX = 0;

Step 2: Save Graphics State and Translate

document.writeGraphicsSave();
document.translate(x0, y0);

Step 3: Create Square for Each Pattern

Rectangle2D.Float square = new Rectangle2D.Float(0, 0, squareSide, squareSide);

Step 4: Set Up Pen for Pattern Square Outline

BasicStroke stroke = new BasicStroke(2);

Step 5: Iterate Through Hatch Patterns

HatchStyle[] hatchStyles = HatchStyle.values();
for (int i = 0; i < hatchStyles.length; i++) {
    // ... (continue with the provided code)
}

Step 6: Restore Graphics State

document.writeGraphicsRestore();

Step 7: Fill Text with Hatch Pattern

TexturePaint paint = HatchPaintLibrary.getHatchTexturePaint(HatchStyle.DiagonalCross, Color.RED, Color.YELLOW);
Font font = new Font("Arial", Font.BOLD, 96);
document.fillAndStrokeText("ABC", font, 200, 320, paint, Color.BLACK, stroke);

Step 8: Outline Text with Hatch Pattern

paint = HatchPaintLibrary.getHatchTexturePaint(HatchStyle.Percent70, Color.BLUE, Color.WHITE);
document.outlineText("ABC", font, 200, 420, paint, new BasicStroke(5));

Step 9: Close and Save Document

document.closePage();
document.save();

Follow these steps, and you’ll successfully add hatch patterns to your Java PostScript document using Aspose.Page.

Conclusion

Incorporating visual elements like hatch patterns can significantly enhance the appeal of your Java applications. Aspose.Page for Java makes this process seamless, allowing you to create visually stunning PostScript documents effortlessly.
