1. Actually
viewer.params is intended to make possible to open generated PDFs by exotic PDF viewers (if any). Let's say the viewer requires to put an extra switch before PDF name:
myexoticpdfreader.exe -input output.pdfIn the case you would need to define
viewer.params=-inputin
pd4browser.properties. If you want to use the property to pass PDF open parameters, you need to specify them fully:
viewer.params=/A "page=3=OpenActions"(the above makes sense only in offline scenarios!)
2. You may define desired page format in
pd4browser.propertiespage.format=LETTERbut why don't you use Pd4Php for that?
