George Sexton commented on PDFBOX-1562:
---------------------------------------

The code I'm using is:

        /**
         * Return PDF Metadata and if necessary create a PDF thumbnail.
         * 
         * @param prop 
         */
        private void getPDFMetaData(Properties prop) {
                String pdfFile = getRepositoryFileName();
                String outputPrefix = pdfFile.substring( 0, pdfFile.lastIndexOf( '.' ))+"_";
                String imageFormat = "jpg";
                int startPage = 1;
                int endPage = 1;
                int resolution=16;      // 16 pixels per inch.

                PDDocument document = null;
                try {
                        document = PDDocument.load( pdfFile );

                        if ( document.isEncrypted() ) {
                                return;
                        }

                        //Make the call
                        PDFImageWriter imageWriter = new PDFImageWriter();
                        boolean success = imageWriter.writeImage(document,
                                                                                                         imageFormat,

                                                                                                         outputPrefix,
                                                                                                         BufferedImage.TYPE_INT_RGB,

                        } else {
                                WebApp.log("getPDFMetaData() Error writing jpg image.");
                        }
                } catch (Exception e) {
                        WebApp.log("getPDFMetaData(this.attachment_id="+this.attachment_id+" File Name: "+this.file_name+")",e);
                } finally {
                        if ( document != null ) {
                                try {
                                        document.close();
                                } catch (IOException ioeIgnore) {
                                }
