Prerequisites

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

  • Aspose.TeX for Java Library: Ensure you have the Aspose.TeX library for Java installed. You can download it from the Aspose.TeX Java Documentation.

  • Java Development Kit (JDK): Make sure you have Java installed on your system. Aspose.TeX for Java requires JDK 1.8 or later.

Import Packages

In your Java project, start by importing the necessary packages for Aspose.TeX. These packages include TeXOptions, OutputFileSystemDirectory, PngSaveOptions, TeXJob, and ImageDevice.

package com.aspose.tex.LaTeXPngConversionSimplest;

import java.io.IOException;

import com.aspose.tex.OutputFileSystemDirectory;
import com.aspose.tex.TeXConfig;
import com.aspose.tex.TeXJob;
import com.aspose.tex.TeXOptions;
import com.aspose.tex.rendering.BmpSaveOptions;
import com.aspose.tex.rendering.ImageDevice;
import com.aspose.tex.rendering.JpegSaveOptions;
import com.aspose.tex.rendering.PngSaveOptions;
import com.aspose.tex.rendering.TiffSaveOptions;

import util.Utils;

Now, let’s break down the conversion process into multiple steps:

Step 1: Set the License

Utils.setLicense();

Ensure to set the license using the Utils.setLicense() method before performing any conversion.

Step 2: Create Conversion Options

TeXOptions options = TeXOptions.consoleAppOptions(TeXConfig.objectLaTeX());

Create TeXOptions for Object LaTeX format using TeXConfig. This sets up the necessary configuration for the TeX engine extension.

Step 3: Specify Output Directory

options.setOutputWorkingDirectory(new OutputFileSystemDirectory("Your Output Directory"));

Specify the file system working directory for the output PNG images. Replace “Your Output Directory” with the desired directory path.

Step 4: Initialize PNG Save Options

options.setSaveOptions(new PngSaveOptions());

Initialize the options for saving in PNG format. You can customize the save options based on your preferences.

Step 5: Run LaTeX to PNG Conversion

new TeXJob("Your Input Directory" + "hello-world.ltx", new ImageDevice(), options).run();

Replace “Your Input Directory” with the path to your LaTeX file. This line initiates the conversion process using the TeXJob class.

Conclusion

Congratulations! You have successfully learned how to use Aspose.TeX for Java to convert LaTeX to PNG images effortlessly. This powerful library streamlines the process, providing you with flexibility and control over your conversion tasks.
