> I have a test image (in attachment) and the following code:

>   public static void main(String[] args) {
>     final String filename = "test.jpg";
>     try (
>         final PDDocument doc = new PDDocument();

>         final ByteArrayOutputStream pdfOut = new ByteArrayOutputStream();
>         final FileOutputStream output = new FileOutputStream("test.pdf")
>     ) {
>       final PDImageXObject jpeg = PDImageXObject.createFromByteArray(doc, IOUtils.toByteArray(input), filename);
>       final PDPage page = new PDPage(new PDRectangle(jpeg.getWidth(), jpeg.getHeight()));
>       doc.addPage(page);
>       try (final PDPageContentStream contents = new PDPageContentStream(doc, page)) {
>         contents.drawImage(jpeg, 0, 0);
>       }
>       doc.save(pdfOut);
>       pdfOut.flush();
>       IOUtils.write(pdfOut.toByteArray(), output);
>     }catch (Exception e) {
>       e.printStackTrace();
>     }
>   }
> {code}
> The image in test.pdf is double sized (and quality is worse) than in original image
