Ghost4J binds the Ghostscript C API to bring Ghostscript power to the Java world. It also provides a high-level API to handle PDF and Postscript documents with objects.
//load PostScript document PSDocument document = new PSDocument(); document.load(new File("input.ps")); //create OutputStream fos = new FileOutputStream(new File("rendition.pdf")); //create converter PDFConverter converter = new PDFConverter(); //set options converter.setPDFSettings(PDFConverter.OPTION_PDFSETTINGS_PREPRESS); //convert converter.convert(document, fos);
Ghost4J Maven artifact is available in a public repository for an easier integration in Maven projects.
If you do not wish to use Maven, binary distributions are available in the Downloads section.

Note: since version 1.0.0, artifacts are available from the Maven Central Repository. Private repositories are not needed anymore.
If you are interested into PS / PDF conversion or rendition have a look at the High level API samples.
If you already know Ghostscript and want to perform advanced operations on documents, have a look at the Core API samples.
If you plan to use Ghost4J in a highly concurrent environment (such as a web server), dont forget to read Thread safety and multi-threading.
