I moved the standard inversion and the blackis1 parameter to the filter in rev 1596007.

I accidentally pressed commit before writing the commit message. I'll see if I can change this.

update: done thanks to http://stackoverflow.com/a/304390/535646 which has 264 upvotes :-)

> While converting a 1 page pdf to an image (both attached below), the image converts properly, however the barcodes colours invert.
> The code used to do the conversion looks like this right now:
>       public static void convertPDFToJPG(String src){
>             try{
>                   //load pdf file in the document object
>                   PDDocument doc=PDDocument.load(new FileInputStream(src));
>                   //Get all pages from document and store them in a list
>                   List<PDPage> pages=doc.getDocumentCatalog().getAllPages();
>                   //create iterator object so it is easy to access each page from the list
>                   Iterator<PDPage> i= pages.iterator();
>                   int count=1; //count variable used to separate each image file
>                   //Convert every page of the pdf document to a unique image file
>                   System.out.println("Please wait...");
>                   while(i.hasNext()){
>                         PDPage page=i.next(); 
>                         BufferedImage bi=page.convertToImage( BufferedImage.TYPE_INT_RGB,  300);
>                         FileOutputStream fos = new FileOutputStream(new File("d:\\slika2_3.jpg"));
>                         //ImageIO.write(bi, "jpg", new File("d:\\pdfimageold.jpg"));
>                         boolean foundWriter = ImageIOUtil.writeImage(bi, "jpg", fos, 300);
>                         count++;
>                   
>                   }
>                   System.out.println("Conversion complete");
>             }catch(IOException ie){ie.printStackTrace();}
>       }
