Information for the software Versions after the 3.5 release
The release version of software called 3.5 contained some important changes to the way
the software operates. These may not affect your operation of the instrument if you do not
use the database or have any practice management integration, but it is important that you
understand them if you do.
The previous versions of the software stored a PDF copy of the printout alongside the
database in an images folder.
The image stored is now a JPEG picture file. The database will operate in the same way as
before except that the 2 eyes plots (threshold tests) are shown on different tabs.
The quality of the JPEG picture file can be set in the options program.
If you currently use the PDF file for another reason, and the JPEG file cannot be substituted
then an additional PDF file can still be created when saving. The location for this can be set
in the options program (PDF tab )
