Hi , Can I watermark single pages in a merge operation with iText Java?
Did you read the documentation? For instance: http://manning.com/lowagie2/samplechapter6.pdf
. I have a requirement toopen each image in memory and watermark them
What do you mean by Image?
and save them after they are merged. is it doable?
There's more than one way to do it, but the workflow you suggest is confusing.
One could watermark PDFs in memory with PdfStamper and then merge them with PdfSmartCopy. That's similar to what is done in listing 6.24 where a stamper writes to a ByteArrayOutputStream of which the bytes are used to add a page to a PdfCopy object (listing 6.25 uses a PdfSmartCopy object to reduce the file size).
One could merge the PDFs with PdfCopy, and then add the watermark in a second pass. That's similar to what is done in listing 6.14 where PdfStamper is used to add a header and a footer. A watermark isn't that different; as a matter of fact listing 6.15 is about adding a background to an existing document.
One could merge and stamp in one go as shown in listing 6.22.Nobody but you can tell you what the best solution is in your case, because only you know the exact requirement. Please read the documentation carefully and you'll have all the arguments you need to make the best decision.
