the root node of a krpano xml file

attributes:

• version
  krpano version used when creating the xml file,
  NOTE - this version number is used to be downward compatible,
  that's important for older plugins or javascript interface examples
  - versions lower or equal then 1.0.5 have a "string"-based get/set interface
  - versions higher then 1.0.5 have a "type-correct" get/set interface
  
• onstart
  action that will performed at the start of the viewing.
• basedir
  base directory for the loadpano action commands.
  this can be a relative or a absolute path,
  the path can include this placeholders:
  
  • %FIRSTXML% - path of the first loaded xml file
  • %CURRENTXML% - path of the current loaded xml file
  • %SWFPATH% - path of the swf file
  • %HTMLPATH% - path of the html file
  the defaultvalue is %FIRSTXML%, that means the paths of all all following loaded XML files by the loadpano() action are relative to the first loaded XML file.
  
  VERSION NOTES / UPDATE NOTES:
  the behavior of version older than 1.0.6 can be restored by setting
  "basedir" to %CURRENTXML%
• logkey
  disable the 'O' key, which switch the log window on/off
  allowed values: true or false, default is true
  note: this parameter is only checked once at startup
• actionintervalbase
  base of interval actions: (for movments like lookto,tween,...)
  
  • "timer"
    
    • movement based on time
    • constant time interval (as good as possible)
    • the number for frames for the movement depends on the power of the computer (when reloading also on the internet connection) (more frames and smoother moving on faster computers and less frames and maybe jerky moving on slower ones)
  • "frame"
    
    • movement based on frame
    • always the same number of frames are used for a movement
    • the time of the movement depends on the power of the computer (short time on faster computers and longer time on slower ones, but always smooth)
    • when doing scripted "zooms" in multiresolution panoramas this helps to keep the movment smooth when tiles are reloaded

The Panorama Image
- set the type of the panorama image
- the paths to the image files
- when tiled or multiresolutions - the tilesize and the size of image

attributes:

• type - type of the panorama image (must be defined)
  
  allowed values:
  SPHERE - for spherical / equirectangular panorama images
  CUBE - for six single cube side images
  CUBESTRIP - the six cube images in one image strip
  
  Depending on type there are different child-nodes:
  Child nodes for type="SPHERE"
  Child nodes for type="CUBE"
  Child nodes for type="CUBESTRIP"
  
• tiled
  is the image tiled or not
  true or false, default=false
  
  if tiled=true then the url of the image should have placeholders for the tileindex
  placeholders:
  

  for the horizontal tile index:  %u, %x, %h or %c
  for the vertical tile index:    %v, %y or %r
  

  there can be one or more "0" between the "%" and the "u,x,c,v,y,r" to align the number and fill the space with 0's.
  
  examples:

  tile_%y_%x.jpg    ->
       tile_1_1.jpg,    tile_1_2.jpg,   ... tile_8_16.jpg

addtionally it's possible to pass parameters to the actions

this action can be called from events with:
  "action(name,parameter1*,parameter2*,...*);"

*parameters are optional!

to access the parameters inside the action use %0-%9 placeholders:
%0 - is the name of the action itself
%1 - first parameter
%2 - second parameter
.. and so on ...

attributes:

• name
  name of the action

notes:

• when loading a other xml file, all action tags remain unchanged unless they are defined again in the other xml. then they will be overwritten with the new ones.

Hotspots are areas in the panorama, which react on mouse hovering or clicking. They can be used to load other panoramas, links to other urls, change the viewing ...

There are currently 2 types of Hotspots:

• Polygonal Hotspots
  these are areas which are defined by a set of points
  
• Image Hotspots
  these are images or flash movies as hotspots
  

The type of the hotspots is defined by their attributes:
- if the "url" attribute is set it is a image hotspot
- if not and there are points defined it is a polygonal hotspot


common attributes for polygonal and image hotspots:

• name
  name of the hotspot, needed for identification / access to it
  
  
• visible
  true or false, default=true
• enabled
  is hotspot enabled to receive mouse events (true or false, default=true)
  new in Version 1.0.7:
  when false then mouse events are routed to underlying objects
  
• capture
  a addtional setting to "enabled":
  - when "enabled=true" and "capture=true" then mouse events are only sent to this hotspot
  - when "enabled=true" and "capture=false" then the mouse events are sent to the hotspot and also to all underlying objects
  (true or false, default=true)
  
• children
  send mouse events also to children objects of the plugin
  (needed for some flash plugins)
  true or false, default=true
• handcursor
  show handcursor when mouse is over (true or false, default=true)
  
  
• keep (NEW - Version 1.0.7 and higher)
  important flag for virtual tour or conntect panoramas!
  possibly values: true or false, default=false
  when keep is set to true the plugin/hotspot is kept when loading other panoramas, otherwise it will be removed
  
  
• zorder
  order of the hotspots, 0-n, default=""
  
  
• alpha
  alpha blend factor (0-1), default="1.0"
  NOTE - when alpha is set to "0" the plugin is invisible, but it still receives mouse events, and it also is drawn by the flashplayer.
  to hide a plugin completely, set "visible" to false
• blendmode
  Flash blending mode
  some modes: "normal", "add", "difference", "multiply", "screen" ...
  default="normal"
  
  look here for all available modes:

Loads a cross-domain policy file from a location specified by the url parameter. By default the Flash Player looks for the policy file located in root of a domain with the filename crossdomain.xml on the server to which a data-loading request is being made. With the crossdomain.url setting the Flash Player can load a policy file from a arbitrary locations.
For more Informations have a look at the Adobe site:
http://www.adobe.com/devnet/articles/crossdomain_policy_file_spec.html

attributes:

• crossdomainxml.url
  Path to the crossdomain.xml on the other server
• allowdomain.domain
  Allow access to other domains (necessary for plugins that want access other domains). You can also specify the special domain "*" to allow access from all domains. Specifying "*" is the only way to allow access to nonlocal SWF files from local SWF files that have been published using Access Network Only for the Local Playback Security option in the Flash authoring tool.
