If the background is not visible, the opened file is added to the existing backgrounds, the current page is assigned the first page of the background and pages are added for the remaining pages of the background. Backgrounds may either be repeating or non-repeating.

Open Source PDF Libraries in Java – JPedal

This is done using the JPedal libraries. The libraries consist of two parts – a GPL portion – jpedalt. Please be aware that the proprietary part is not released under the GPL and is available for non-commercial use only.

For Linux and Windows go to http: For the Mac go to http: Run Jarnal and examine the about box, noting down what it reports your home directory is; under windows it tends to be in an obscure location. Go to that directory and edit the file jarnshell. However, you may still wish to do this if you are having problems with particular pdf files] Go to the ghostscript site and download and install ghostscript for windows not ghostview. To use it you must either start jarnal with the -g flag on the command line, or under View Background Quality make sure that the “Use External Renderer” box is checked.

Install xpdf if it is not already installed.

Xpdf ships with most linux distributions, but may not be installed by default. For example, in an rpm based distribution, locate the xpdf rpm and install it. If xpdf is not shipped with your distribution, go to the xpdf website to download and install it.
