How to Render LaTeX in Java
This tutorial will demonstrate how to execute TeX and get output in Java.
Use JLaTeXMath to Render LaTeX in Java
Import jlatexmath as a maven project in your eclipse or IDE, and use the examples and run your LaTeX in Java. Make sure the maven dependencies are already installed in your IDE.
Example:
package org.scilab.forge.jlatexmath.examples.export;
import java.io.IOException;
// This Class is used to render the latex
public class JAVA_TEX {
public static void main(String[] args) {
String demo_latex = "\\begin{array}{|c|l|||r|c|}";
demo_latex += "\\hline";
demo_latex +=
"\\text{Matrix}&\\multicolumn{2}{|c|}{\\text{Multicolumns}}&\\text{Font sizes commands}\\cr";
demo_latex += "\\hline";
demo_latex +=
"\\begin{pmatrix}\\alpha_{11}&\\cdots&\\alpha_{1n}\\cr\\hdotsfor{3}\\cr\\alpha_{n1}&\\cdots&\\alpha_{nn}\\end{pmatrix}&\\Large \\text{Large Right}&\\small \\text{small Left}&\\tiny \\text{tiny Tiny}\\cr";
demo_latex += "\\hline";
demo_latex += "\\multicolumn{4}{|c|}{\\Huge \\text{Huge Multicolumns}}\\cr";
demo_latex += "\\hline";
demo_latex += "\\end{array}";
try {
Convert.toSVG(demo_latex, "demo_latex.svg", false);
Convert.toSVG(demo_latex, "demo_latex_shaped.svg", true);
Convert.SVGTo("demo_latex.svg", "demo_latex.pdf", Convert.PDF);
Convert.SVGTo("demo_latex_shaped.svg", "demo_latex_shaped.pdf", Convert.PDF);
Convert.SVGTo("demo_latex.svg", "demo_latex.ps", Convert.PS);
Convert.SVGTo("demo_latex.svg", "demo_latex.eps", Convert.EPS);
} catch (IOException exception) {
throw new RuntimeException(exception);
}
}
}

The code above will execute the LaTeX array syntax and generate output in .ps, .svg, and .pdf.
Some warnings may occur, but that can be ignored.
Files output:
The .ps, .svg, and .pdf files have the same written output below.
