Hello, I read this thread with great interest. We also have to process and merge large PDF files. While we haven't had files as big as described in this thread, we have had problems with memory consumption on files as small as 80MB. Stamping an 80MB file with the old PdfReader constructor took upwards of 900MB of heap size. With the new constructor taking a byte array, it is down to 400MB. This is still a lot of memory and will limit the size of the files we'll be able to process.
So, my question is, is iText looking at ways to decrease memory usage? Are you planning any new apis that stream the documents in and out of memory as opposed to having the entire doc in memory multiple times over?
