Convert PostScript to PDF using Java

[ ]

Aspose.Page for Java PS to PDF converter allows to convert PostScript (PS) file to PDF document on any OS for which Java Virtual Machine exists.
It is necessary to do several steps in order to perform PS to PDF conversion:

  1. Initialize an input stream for input PS file.
  2. Initialize an output stream for output PDF document.
  3. Create an instance of PsDocument from created earlier input stream.
  4. Use PdfSaveOptions to specify AdditionalFontsFolder and SuppressError boolean value.
  5. Create an instance of PdfDevice from created earlier output stream.
  6. Save PostScript document as PDF with PDF save options.
  7. If SuppressErrors value was true, as it is by default, It is possible to see what errors were thrown during conversion of PS to PDF.

Following code snippet shows how to convert PS to PDF document in Java:

// For complete examples and data files, please go to

        // The path to the documents directory.
        String dataDir = Utils.getDataDir();
        // Initialize PDF output stream
        FileOutputStream pdfStream = new FileOutputStream(dataDir + "PStoPDF.pdf");

        // Initialize PostScript input stream
        FileInputStream psStream = new FileInputStream(dataDir + "");

        PsDocument document = new PsDocument(psStream);

        // If you want to convert Postscript file despite of minor errors set this flag
        boolean suppressErrors = true;

        //Initialize options object with necessary parameters.
        PdfSaveOptions options = new PdfSaveOptions(suppressErrors);
        // If you want to add special folder where fonts are stored. Default fonts folder in OS is always included.
        //options.setAdditionalFontsFolders(new String [] {"FONTS_FOLDER"});

        // Default page size is 595x842 and it is not mandatory to set it in PdfDevice
        com.aspose.eps.device.PdfDevice device = new com.aspose.eps.device.PdfDevice(pdfStream);
        // But if you need to specify size and image format use following line
        //com.aspose.eps.device.PdfDevice device = new com.aspose.eps.device.PdfDevice(pdfStream, new Dimension(595, 842));

        try {
  , options);
        } finally {

        //Review errors
        if (suppressErrors) {
            for (Exception ex : options.getExceptions()) {

Let’s consider PdfSaveOptions. Using this class we can assign different conversion parameters while converting PS to PDF.

  • AdditionalFontsFolder specifies locations where to find fonts. System fonts folders are always included by default.
  • SuppressError controls behaviour of PS to PDF converter when non-critical errors are appeared. If value is true than it is possible to view a list of such errors after conversion in Exceptions field. Default value is true.
  • Debug allows outputting debug information to console. Default value is false.
