It's been awhile since I attempted to create a tour with my software and have a few questions. Hopefully someone can give me some guidance!
1) Is there any complete, downloadable PDF form of the TOUR information?
No - not yet.
2) If I want to customize my tour in any way, other than the basics, do I use the Krpano tools for that???
Depends on what you want to do. Are using the latest APT V1.1 beta 9 which has the most features so far?:http://www.autopano.net/forum/t9204-apt-v1.1-beta-9
For instance, I want to be able to limit how much people can ZOOM on a pano. Do I need the Krpano tools for that?
No - right-click in 3D editor image and set zo0m limits (or use the icons above the image). See screenshot below.
If I have a pro license, do I also then already have Krpano license???
When you say 'Pro license' do you mean Autopano Pro license? If so, then no that's not the same as a krpano licence. You can purchase a krpano license from the Kolor web shop:http://www.kolor.com/buy/software/krpano/krpano-flash-panorama-viewer-unlimited-domain-license.html
If you already have an Autopano Giga license then you can get a discount of 10 Euros on the krpano license if yoiu purchase via the Kolor web shop.
I am a little confused by your question because Autopano Tour is currently only available as a bundle with Autopano Giga (and not with Autopano Pro) although that will change soon when Autopano Tour will be unbundled from APG and only offered as a separate product.
Autopano Tour offers basic tour authoring capabilities without your having a krpano license. But if you also have a krpano license, and register that licnse in APT, then more advanced features are enabled in Autopano Tour.
I do wish there were more info about the tours in general. There seems to be a lot about the stitching process, but then not much (that you don't actively have to search out) in the FAQs or guidelines.
True - or ask here of course.
Kolor plans to complete documentation for APT when it is in a more stable state as I understand it.
Meantime ask away, there are users who may be able to help.
