CreatePDFfromLaTeX_Java_LTXtoPDF.java

// This code example demonstrates how to create a PDF from LTX source file.
// Working directory
String dataDir = "D:\\Files\\Tex\\";

// Create typesetting options.
TeXOptions options = TeXOptions.consoleAppOptions(TeXConfig.objectLaTeX());

// Specify a file system working directory for input.
options.setInputWorkingDirectory(new InputFileSystemDirectory(dataDir));

// Specify a file system working directory for output.
options.setOutputWorkingDirectory(new OutputFileSystemDirectory(dataDir));

// Specify memory stream as output terminal.
options.setTerminalOut(new OutputMemoryTerminal());

// Set options for rendering into PDF format.
options.setSaveOptions(new PdfSaveOptions());

// Run typesetting.
new TeXJob(dataDir + "sample.ltx", new PdfDevice(), options).run();
