Specifying an image once in a PDF

[Clark, Raymond C]

Hi,

I am using PDFBox in production and it is working great.  I have a question on 
how I am using it.  I have a method that puts an image in a PDF as you can see 
below.  Since I have the same image on multiple pages it seems to me that this 
code can/is drawing the same image on multiple pages.  Is there a way to drop 
an image into a PDF only once and then reference it on the various pages 
specifying the location it is to be printed at?  I hope that I made myself 
clear, I'm trying to avoid multiple copies of the same image in the PDF.

Here is my code:

public void drawImage(Column column, float xPosition, float yPosition) throws 
ProductRequestException {
        float scale = 1f; // alter this value to set the image size
        float imageYPosition = PDFGeneratorHelper.getImageYPosition(column, 
yPosition);
        float imageXPosition = PDFGeneratorHelper.getImageXPosition(column, 
xPosition);

        // Does NOT compress GIF and other image files
        PDImageXObject pdImage;
        try {
                pdImage = PDImageXObject.createFromFile(
                                new 
File(getClass().getClassLoader().getResource(column.getImagePath()).toURI())
                                        .getAbsolutePath(), document);
        } catch(IOException ioe) {
                throw new ProductRequestException("IOException 1 in drawImage", 
ioe);
        } catch(URISyntaxException use) {
                throw new ProductRequestException("URISyntaxException in 
drawImage", use);
        }
        pdImage.getCOSObject().setName("BDSImageName", column.getImagePath());
        try {
                if (column.getImageWidth() == null) {
                        contentStream.drawImage(pdImage, imageXPosition, 
imageYPosition, pdImage.getWidth() * scale,
                                        pdImage.getHeight() * scale);
                } else {
                        contentStream.drawImage(pdImage, imageXPosition, 
imageYPosition,
                                        
Float.parseFloat(column.getImageWidth()),
                                        
Float.parseFloat(column.getImageHeight()));
                }
        } catch(IOException ioe) {
                throw new ProductRequestException("IOException 2 in drawImage", 
ioe);
        }
}

Thank you,
Ray
