This short guide describes how to add background image to PDF using Java. You will get details to set the IDE for the development, a list of steps, and a sample code for setting the PDF background image using Java. Various API details will be shared to customize the output PDF using different properties and methods.

Steps for Adding Background Image in PDF using Java

1. Set the IDE to use Aspose.PDF for Java to set the PDF background image
2. Set the file names for the input PDF, background image, license, and output PDF
3. Load the input PDF file into the Document class and iterate through all the pages
4. Create the ImageStamp, set the input image in it, and set the flag for the background to true
5. Set the size of the image stamp equal to the current page size
6. Add the stamp to the page and repeat the process for all the remaining pages
7. Save the output PDF with a new background image

These steps explain how to set the background PDF images using Java. Set all the desired file names, set the license, create a Document class object, load the source PDF file into it, and iterate through all the pages in it. Create the ImageStamp using the input background image file, set the Background flag to true, set the stamp size equal to the size of the current PDF page, and add the image stamp for each page before the output PDF is saved on the disk.
