I was wondering if anyone has seen this problem and solved it. I am not able to
create a PDF using a JPEG2000 image larger than about 200MB. I'm not sure that
it really matters what type of image it is (JPG, Tiff, etc) but I happen to be
using JPEG2000 images. This is a big problem because most of the required
images that we work with are 1GB or greater. Currently when trying to create a
PDF with an JPEG2000 greater than about 200MB I get an JVM OutOfMemoryError in
32bit java version "1.6.0_25-b06" and the 32 bit version of JBOSS 5.1.0.GA on
Windows XP Pro x64 version 2003 Service Pack 2. With JAVA_OPTS=%JAVA_OPTS%
-Xms128m -Xmx512m -XX:MaxPermSize=256m and itextpdf-5.0.7. I've traced the code
and the error occurs in PdfWriter.java when adding the image to the document. I
have not tried the latest itextpdf-5.1.2 yet but I have looked at the source
and the image creation part does not seem to have changed. I have recently
tried 64bit Java and did not get the OutOfMemory error but I consistently get
the Adobe Reader 9 "Insufficient data for an image" error. I've looked at the
pdf bytes and the header, trailer, etc. seem ok. My thoughts on how to handle a
large JEPG2000 file is simply to compose all parts of the PDF first (header,
etc.) with a handle to where the byte stream of the image will go and when it¹s
time to write the PDF, stream the JPEG2000 image at that time so that at no
time will you have to keep the entire image in JVM Heap. Please let me know if
you think this is a viable solution and or what your ideas on the subject are.
Thanks,
Martin
