How to connect.

Put the folder "add_hotspot" in the root folder with the tour and write in the file "tour.xml":

   <krpano .... >
    <include url="add_hotspot/plugins_l/add_hotspot.xml" />     
    <include url="add_hotspot/plugins_l/editor/add_hotspot_2.xml" />  	

The plugin works, when you open a tour in the Internet browser. Will not work when opening with "Krpano Tools".

Disable the editor.

When finished, in the file "tour.xml": delete the line:

  <include url="add_hotspot/plugins_l/editor/add_hotspot_2.xml" />

Reload the tour - the editor panel will disappear.
When placing on the server or transferring the tour to the customer, delete the editor folder "editor" which is located along the path add_hotspot/plugins_l.

Change the location of the plugin and the name of the main XML file.

For example, your main file is test.xml and you want to place the folder with the plugin in the skinfolder. Put the "add_hotspot" folder in the skin folder and write it in the "test.xml" file.

    <include url="%SWFPATH%/skin/add_hotspot/plugins_l/add_hotspot.xml" /> 
    <include url="%SWFPATH%/skin/add_hotspot/plugins_l/editor/add_hotspot_2.xml" /> 	

In the add_hotspot/plugins_l/plugin_a/style_addhs.xml file, write:

  <addhs_settings FIRSTXML="test" 

FIRSTXML - name of the main XML file.
path - path to the location of the plugin folder.

Plugin activation.


The plugin will only work with your krpano license.

You need to send me the email that you used to register your krpano. It can be seen in "krpano Tools".

After that, you will receive an email with a link to download the plugin and a key file with activation instructions.

The plugin creates local hotspots (inside the scene!), But names for all hotspots are created different. The scene name is written in the plugin attribute. Keep this in mind when creating hotspots and assigning them other actions!

Panel for hotspots creating.


For convenience, panel moves with mouse. Clicking the triangular button opens/closes panel.

Purpose of buttons:

shesterenka - open the panel for configuring the attributes of a hot spot.

teg - open the window with the hotspot code.

update - to update hot spots. If the hotspot is created dynamically, then after updating it is available for editing.

Title - if necessary, enter a description of the hotspot, the default is the name of the hotspot. Click on the round button (or on the "Title"). It will turn green - the description will appear, when you hover over a hotspot.

Image icon - click on the icon to open the explorer to select the image hotspot. Images must be placed along the way "add_hotspot/picture".

Copy "+" - creates a copy of the selected hotspot. Hotkey "+".

Delete - delete selected hotspot. Hotkey "Delete".

Add hotspot - create hotspot. Hotspot appears in the center of the window with a pre-selected image.

Image - click the button if no hotspot is assigned to actions from the other tabs below.

Drag - lock/unlock button for moving active hotspot.

Drag all - lock/unlock button to move all created hotspots.

del_edit - Saving a project.
If backup is enabled, then first you will be prompted to save a copy of "tour.xml - backup-2021.12.14-12.20.52.xml" where the date and time will be indicated, then you will be prompted to save "tour.xml" with created hotspots. Replace the existing "tour.xml" file with the suggested one. If the file name is different, then the one you specified will be substituted

You can disable saving a backup in add_hotspot/plugins_l/plugin_a/style_addhs.xml by setting backup="false"

target - turns on/off the crosshair for easy positioning of the created hot spot.

viewYes - show/hide all hotspots created by the plugin.

arrov2 - show/hide joystick on hotspot.

joystik The joystick appears at the nodal point of the hotspot. Press and move the cursor left/right - rotation along the x-axis (attribute "rx"). Cursor up/down-rotation along the y axis (attribute "ry").
Under the joystick, the rotation button on the z axis. To change, press and move the cursor left/right (attribute "rz").
Above the joystick is the zoom button - press and move the cursor left/right ("Scale" attribute).

Joystick example. YouTube.

Distorted - Turn on/off distortion.

closeZ - Block the hotspot from editing. The hotspot will not be dragged with the mouse. Changes to the hotspot parameters will be disabled.

closeZ - temporarily disables the action of all hotspots (on over, on out, onclick, ondown, onup, onhover), which allows you to work with hotspots calmly (for example, when pressed, it will not send you to another scene). Doesn't disable attributes styled like "addevent".

closeZ - installs in the hotspot enabled=false. The hotspot is disabled and does not respond to the mouse. If you collapse and expand the editing panel, that enabled will be installed in true and the hotspot will be available for editing again.

- selective copying of attributes.

closeZ - copy attributes of the selected hotspot (Ctrl+C).

closeZ - paste the copied attributes (Ctrl+V).


closeZ - selecting attributes to insert. Clicking this button opens a list of attributes. Enable/disable the necessary attributes for copying.

Grabbing the triangle at the bottom right, you can expand the panel. Additional tabs will open. The tabs are in a collapsed state and are expanded by clicking on the triangle or the name inside the tab.
Tabs are needed to assign actions when clicking on a hotspot and to create text, polygonal and video hotspots. The tab is selected by pressing the corresponding round button, the button will turn green. When you click on a hotspot, its corresponding tab becomes active.


The list includes all global hotspots and local hotspots of the open scene, including hotspots not created by the plugin.

  • List of hotspots - drop-down list of hotspots.
    Hovering over the name in the list rotates the scene to this hotspot. A click on a name in the list activates it and the name appears in the search bar.
  • Search - hotspot search string.
    Enter a name and press Enter. A view of this hotspot will be established and it will become active for editing.
    When you click on hotspots (activation), the name of the hotspot appears in this line, it is available for copying via keyboard shortcuts ("Ctrl + C").

Advanced options.


By default, a hotspot image is created without assigning any actions to it. In the tab "Manual setings (direct input)" you can set its parameters manually.

How to change parameters:

Select a hotspot by clicking on it, name of edited access point appears on first line. Edited hotspot is moved by mouse and positioning coordinates are immediately displayed on corresponding buttons.
Clicking in an empty place on screen resets selection!

Changes to parameter are made by pressing left mouse button and moving it to the left (decrease the parameter) and to the right (parameter increase). Farther the mouse is moved away from click location, when faster parameter changes.
The changes are directly applied to hotspots and you can be visually controlled result.
Parameters that have two states (on or off) switch by clicking on button.
Clicking on button highlights it with a green frame, direct keyboard input becomes available - numbers (right on keyboard), percentage ("5" button of top row of keyboard).
Backspace clears the numeric value on the button.
Selected parameter is also displayed in the line above buttons, where you can edit/delete, copy, paste. To enter, press "Enter" button.

You can also edit local hotspots. Make changes and open the active hotspot settings window. Copy the changed parameters and paste into the hotspot.

Attribute window - open a window to display the parameters of the active hotspot.

Select a hotspot by clicking on it - its attributes will be displayed in this window. You can select and copy parameters by pressing "Ctrl + C". The size of the window can be changed by grasping the lower right corner. The text inside the window is automatically distributed across the width. The window can be moved by grasping the top. Entering parameters in the window is not possible.

Action list - open a window with a list of frequently used actions.
You can use it as a draft, you can copy ("Ctrl + C"), paste ("Ctrl + C") actions.
The list is along the way add_hotspot/plugins_l/actionSM.html - you can fill in the required information.

Info "action" - opens the Krpano website with background information on actions and functions .

Info "hotspot" - opens the Krpano website with background information about settings of hotspot.

3d - Show 3D coordinates and invert control controls.
This tool should be used when working in a 3D model or with depth maps. When you launch it, the model center view from the outside changes. The X Y Z coordinate axes are set. When creating a hotspot in this mode, the following attribute values are set:
Moving the hotspot with the mouse is blocked. The position of the hotspot in space changes in the Cartesian coordinate system by changing the parameters tx ty tz. There are round buttons on the axes. Click on the button and drag - the hotspot will move along this axis.

Hotspots with 3d coordinates are created in the 3D model, in this case, the attribute depth=0.
Dragging the hotspot with the mouse in the 3D model takes place according to the coordinates tx ty tz, if depth=0.

Example of working in a 3D model.

ath - horizontal coordinate (-180...180).
atv - vertical coordinate (-90...90).
alpha - change alpha (0 - 1).
rotate - rotate (-360...360).
speed - changing speed of main parameters from 0 to 10.
rx - rotation around its own x axis (in degrees).
ry - rotation around its own axis y (in degrees).
rz - rotation around its own axis z (in degrees).

parameters "rx", "ry", rz " are changed only when the parameter "distorted" is enabled".

ox - offset along «x»-axis (in px).
oy - oy - offset along «y»-axis (in px).
width - width change (pixels.) The value of "prop" is proportional (by default, pixels).
height - height change (pixels). The value "prop" is proportional (by default "prop"). To enter the "prop" value, press the "p" key.
scale - changes scale of hotspots. Press and move mouse in the pressed state to the left ( zoom out) or to the right (zoom in).
edge - positioning (9 variants).
zorder - display sequence number (visibility). A higher value brings to the foreground (1-100).
capture - mouse capture. if the value is" false", clicking on the hot spot and shifting to the side does not prevent moving the panorama (true/falce).
distorted - on/off distorted hotspot.
zoom - should the size of the hotspot image change together with the pano when zooming.
flying - this setting interpolates automatically the ath/atv and scale values to the current viewing values. The value range is from 0.0 to 1.0. At 1.0 the hotspot image will be locked always to the middle to screen and it's size will be relative to 1000 pixel in screen height.

actions/functions to be called when.
  • onover - user hovered the mouse pointer.
  • onhover - user hovered the mouse pointer, called 15 times per second while cursor over the hotspot.
  • onout - user has removed cursor from the hotspot.
  • onclick - user clicked on the hotspot.
  • onloaded - the hot spot is loaded.

handcursor - show hand when hovering hotspot (true/falce).
enabled2 - all generated hotspots are global and the values "enabled" and "visible" become active in the scene that is listed in the hotspot. If enabled2="falce", then regardless of the prescribed scene hotspot will be turned off. In edit mode enabled2="true" (true/falce).
visible2 - if visible2 = "falce", then regardless of the registered scene, the hotspot will be invisible. In edit mode visible2="true" (true/falce).
depth - the internal 3D rendering depth - that's the distance of the 3D object to the screen. For 2D viewing this has no visible effect, but for stereo 3D/VR viewing this can be important setting. E.g. use smaller values for a stronger 'pop-out' effect. When a hotspot image should be infinity far away (like the pano image itself, e.g. to pixel-perfectly match the pano-background) then an 'invalid' value (e.g. a String like "off") should be used for the depth setting - e.g. depth="off".

url - the path/url to the hotspot image file.
html - the text (in the text of the hotspot).
tx - 3D x offsets (only available for distorted hotspots).
ty - 3D y offsets (only available for distorted hotspots).
tz - 3D z offsets (only available for distorted hotspots).
renderer - the visualization for the hotspot (webgl/css3d). By default - "webgl"
torigin - the position of the access point.
world - the position of the hotspot is "global" / "world». This means that the position will always be the same, regardless of the panorama or the user's viewing position.
image - the position of the hotspot will be relative to the current position of the panoramic image.
view - the hotspot position will be relative to the current viewing position.
By default - "world".
depthbuffer - when this option is enabled, hotspots can cross other hotspots (with deepbuffer = true) or depth map geometry in 3D space (true/falce).
alphachannel - Setup the alpha-channel / transparency-channel usage and source. For images and videos. Usage case: there is currently no browser-support for transparent videos, so as alternative a video with the alpha-channel as extra image on the right (Side-by-Side) or at the bottom (Top-Bottom) can be used. Example
chromakey - With the chromakey setting a certain color in the hotspot image or video can be used as alpha / transparency mask. The typical usage would be Greenscreen or Bluescreen videos. Example.
Pressing "Backspace" button clears the digital value of the attribute on button.
More information on assignment of hotspot attributes can be obtained on website krpano.
group - assign or change group of the hotspot.
keep - make a hotspot local or global. When set to "true", the hotspot will appear in the panorama where it is registered and will not disappear when switching to other panoramas.

  • sound name - use the name "sound_hs_addhs" and when you play another sound, this one will be turned off. If you choose a different name, then the sound will be played simultaneously with the other running ones. For disable it, you will need to use an action with this name. For example: stopsound (name).
  • URL - full path to the audio file.
  • volume - playback volume(0-1).
  • cycle - play continuously(true) or once(false).

For example: play_soundSM(sound_hs_addhs, 'add_hotspot/sound/2.mp3',0.5, false);

You can generate the code directly in the tab, but the audio file must be in the folder add_hotspot/sound/ and by default, the name is used "sound_hs_addhs":

  • Select an audio file by clicking on the sound icon in the tab.
  • Set the path.
  • Set the volume.
  • Set the cycle.
  • Expand the editor panel to the width and a line with the code will appear.

  • In frame - to open a link in a frame (window in a window). Unfortunately, it does not work on IOS yet (only HTML5).

To select, click on the selected option, indicator will turn green.
Choose a hotspot and enter address of site to open (or copy "Ctrl+C" and paste into line "Ctrl+V"), press "Enter".
You can try entering links here.

Example creation of hotspots, which opening URL links.

Insert a patch from PTGui.


PTGui This tab allows you to ideally place part of image (pixel per pixel) extracted from panorama.
How to extract part of image is described in detail on krpano forum, i recommend to carefully read! Next, edit it at your own discretion (insert open door, change color of object, etc.). And you can insert an image using this tab without xml code edits.
Inserting an image:
  • Place edited image along path add_hotspot/picture/.
  • Activate tab by clicking Patgh PTGui.
  • Select created earlier image by clicking on icon "Select image" and create a hotspot by tapping "Add hotspot" .
  • In tab on "image:" the name of selected file appears.
  • If image is large, create a smaller copy for mobile version, click on"Mobile image" and select this image.
  • If you extracted an image as described in krpano forum, then you should have these settings saved: "hfov","yaw","pitch","roll". Enter these parameters into corresponding cells, each time pressing "Enter".
If you have done everything correctly, image will be clearly aligned with your place in panorama.

If necessary, select desired predefined actions, activate by clicking on name (indicator turns green):
  • onover-show - when you hover mouse, image appears smoothly.
  • onout-hide - on out mouse - image faded away.
  • show/hide - clicking on image will toggle visibility.
Button action code - if you create a button to control visibility of image, you can generate a visibility control code for created image and paste it into button:
  • show - show image.
  • hide - hide image.
  • show/hide - toggle visibility.
When selected action is activated, corresponding code appears in line, use it for your button.
Copy to clipboard - copy the contents of the line to the clipboard for subsequent insertion.
Example of creating an opening door.

Create text hotspot.

An example of creating a text hotspot.

This tab allows you to create and edit text hotspots. Detailed information about the attributes of the text hot spot is here .
All Windows with digital values allow you to enter parameters from the keyboard, insert, copy. As you enter, press " Enter".

  • Create text hotspot - create a text hotspot with default settings.
Panel of change of radius of corners and thickness of borders.
  • The change in all radii - hover over upper average round point, hint "all round " will appear and button will become green. Press the button and move the cursor to the right (increase the radius of all corners) or to the left (decrease the radius of all corners). The angle radius value will be displayed next to the button.
  • Changing the radius of each corner - opposite each corner is a similar button. It changes the radius of the corresponding angle by the same principle.
  • Changing the thickness of the border - the button is located at the bottom of the border. The principle of changing the thickness of the border is the same as changing the radius of the corners.
Panel for changing the parameters of the hotspot shadow.
  • Shadow hotspot - click on the button and move the mouse without releasing - the shadow of the hotspot will shift accordingly.
  • X offset - displays the value of the shadow offset along the x axis.
  • Y offset - displays the value of the shadow offset along the y axis.
  • Blur - press button and, without releasing, move mouse to right (increase blur of shadow), to left (decrease blur of shadow).
Changes in color and transparency.
  • Color fill - fill color hotspot.
  • Color border - border color hotspot.
  • Color shadow - color hotspot shade.

Clicking the button opens the color and transparency editing panel. Clicking on the hotspot displays its value in the upper right square, the color is displayed in the left square. Clicking on the right box returns to the original spot color.

css Text
  • Html - enter the text displayed in the hot spot. You can use multiple HTML tags, simple CSS styles, or tags to generate text.
  • Css - text style. Leave a space between the colon and the "color" and "font-size" parameters!
  • Size text - change height of text.
  • Shadw text - is the same panel as Shadw hotspot, only the parameters are applied to the text shadow.
padding Text indent changes.
  • Padding - four buttons for changing indent text on four sides.
Change text color and shadow.
  • Color text - change text color.
  • Text shadow color - shadow color change.
Additional settings.
dop_param expand the panel, grabbing the lower right corner, the buttons of additional parameters will open.
  • oversampling - upscale the internal bitmap rendering target by the given oversampling factor for a higher-resolution (sharper) text.
  • vcenter - vertically center the text within the given plugin height.
  • wordwrap - set if the text should automatically wrap around (line-break) to new lines when the text doesn't fit into the current line.
  • bg - turn on, turn off the background.
  • mergedalpha - by default the alpha transparency of the background will be applied also to the border and shadow, but by disabling that setting, it would be possible to render the border and shadow with their own and independent alpha transparency.
  • mipmapping - enable mipmapping - this reduces aliasing effects when displaying the text as scaled-down element.

Create polygon hotspot.

Example of creating polygonal hotspot.

This tab allows you to create and edit polygonal hotspots. Detailed information on the assignment of polygonal hotspot attributes here .


Create and edit - mode of creating and editing polygonal hotspots. Active - red button.
To turn the mode on or off, press the button or the "E" key, start and finish drawing the hotspot - press the "space bar", to create a point - click with the left mouse button.
In the edit mode, click on the hotspot - there will be nodal points at the corners. Grabbing the point, you can move the angle. When you hover over a point, two buttons "+" (create point) and "x" (delete point) appear.

There are two tabs in the panel Default settings and Hotspot.

Bookmark "Default settings"


Here you can configure the default settings (polygon hot spots style). These parameters will be applied to newly created hotspots.

  • Show text - pop-up text when hovering over the hot spot. enter if necessary. By default, the name of the hot spot is displayed. If the text is not needed - remove from the line.
  • Polyline - polygon or polygon line creation mode.
