Java PostScript Radial Gradient with Aspose.Page

Introduction

Welcome to our step-by-step guide on adding Radial Gradient 2 in Java PostScript using Aspose.Page for Java. This tutorial will walk you through the process of creating a PostScript document with a beautiful radial gradient, enhancing your Java applications with visually appealing graphics.

Prerequisites

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

  • A working knowledge of Java programming.
  • Installed Java Development Kit (JDK) on your machine.
  • Aspose.Page for Java library, which you can download from the Aspose.Page Java documentation.

Import Packages

In your Java project, import the necessary packages for Aspose.Page:

import java.awt.Color;
import java.awt.MultipleGradientPaint;
import java.awt.RadialGradientPaint;
import java.awt.geom.AffineTransform;
import java.awt.geom.Ellipse2D;
import java.awt.geom.Point2D;
import java.io.FileOutputStream;
import com.aspose.eps.PsDocument;
import com.aspose.eps.device.PsSaveOptions;

Step 1: Set Up Document Directory

Define the path to your document directory:

String dataDir = "Your Document Directory";

Step 2: Create Output Stream

Create an output stream for the PostScript document:

FileOutputStream outPsStream = new FileOutputStream(dataDir + "RadialGradient2_outPS.ps");

Step 3: Create Save Options

Create save options with A4 size:

PsSaveOptions options = new PsSaveOptions();

Step 4: Create PS Document

Create a new PS Document with the page opened:

PsDocument document = new PsDocument(outPsStream, options, false);

Step 5: Create a Circle

Define a circle using the Ellipse2D.Float class:

Ellipse2D.Float circle = new Ellipse2D.Float(200, 100, 200, 200);

Step 6: Define Gradient Colors

Create arrays of colors and fractions for the radial gradient:

Color[] colors = { Color.WHITE, Color.WHITE, Color.BLUE };
float[] fractions = { 0.0f, 0.2f, 1.0f };

Step 7: Create AffineTransform

Create an AffineTransform for the radial gradient:

AffineTransform transform = new AffineTransform(200, 0, 0, 200, 200, 100);

Step 8: Create Radial Gradient Paint

Create a RadialGradientPaint with the specified parameters:

RadialGradientPaint paint = new RadialGradientPaint(new Point2D.Float(64, 64), 68, new Point2D.Float(24, 24),
        fractions, colors, MultipleGradientPaint.CycleMethod.NO_CYCLE, MultipleGradientPaint.ColorSpaceType.SRGB,
        transform);

Step 9: Set Paint and Fill Circle

Set the paint and fill the circle with the radial gradient:

document.setPaint(paint);
document.fill(circle);

Step 10: Close Page and Save Document

Close the current page and save the document:

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

Congratulations! You have successfully added Radial Gradient 2 in Java PostScript using Aspose.Page for Java.
