Use PdfWriter.releaseTemplate(). Use this method to release the memory used by
a template. This method writes the template to the output. The template can
still be added to any content but changes to the template itself won't have any
effect.

> Hi,

> PdfTemplate pdfTemplate =

>
> Graphics2D g2 = pdfTemplate.createGraphicsShapes(width, height);

> This code runs well up to 1000 pages and gets "Exception in

> I have increased Java heap size to 512Mb. Works fine up to
