What format is the image in? IIRC, JPEG files are pretty much copied
verbatium, while other formats need to be parsed and coverted and so
forth. I'm guessing that JPEG images will have a smaller memory
footprint.

Subject: [iText-questions] java.lang.OutOfMemoryError
The OutOfMemoryError occurs at the cb.addImage(img) line. The
image I'm trying to write is about 210,703 KB. I'm running the below
code fragment from a Servlet in JBOSS-5.0.1.GA, Itextpdf-5.0.7, and java
version "1.6.0_20".
I'm wondering if there is a simple fix to this problem like
turning streaming to disk on for large images which I've read does occur
so I'm not sure what the problem is. This problem does not occur in a
standalone Java class but so far only when run in my servlet container.
I'm running the 32 bit version of JBOSS so I can't up the VM (-Xms1280m
-Xmx1280m) memory any more then I already have. The images are only
going to get bigger.

Code fragment:
PdfWriter writer = PdfWriter.getInstance(document, new
FileOutputStream(outPutFile));
document.open();
PdfContentByte cb = writer.getDirectContent();
Image img = Image.getInstance(firstImageName);
PdfLayer group = new PdfLayer("Layers", writer);
PdfLayer layer1 = new PdfLayer("image", writer);
group.addChild(layer1);
cb.beginLayer(group);
cb.endLayer();
cb.beginLayer(layer1);
cb.addImage(img); // the addImage where the out of memory occurs
cb.endLayer();
document.close();
Thanks.
