Java PDF Viewer General properties
This section gives information about the General properties tab for the PDF viewer, the function of the different flags and how they can be changed. Please note, we are constantly adding new functionality to the properties file and therefore the documentation contained here is for version 4.3 of JPedal. If a flag is not present in your properties file then the functionality is not available for your version.
