I m come from China
my english is poor,but read the following please,I need help.

I want to add polygon hotspots on my pano and my KRpano version is 1.18.

the notes of krpano 1.18 released :

• Improved HTML5 Support
  • Panoramic video support for HTML5
    • Better performance and higher quality than Flash in many cases.
    • Free seeking during loading.
    • Works on mobile devices with WebGL support (iOS 8, Android Chrome, Android Firefox). Has a special iPhone support (normally panoramic video wouldn't be possible in the iPhone browser due iOS limitations).
    • New videointerface skin with many new features - direct seeking, video quality changing, projection menu, mobile support, flat-view fallback with moving and zooming when there is no WebGL support.
  • Support spherical and cylindrical panoramic images in HTML5 (with WebGL) and dynamic transitions between spherical and flat projection.
  • Polygonal hotspot support.
  • Contextmenu for touch devices.
  • Styleable Contextmenu.
  • showtext() support.
  • Gyro support for Android Chrome, Android Chrome and Windows Phone.
  • Improved mobile devices / browser support.
  • Improved pano rendering and blending.

The third means krpano 1.18 is supports the polygon hotspots for html5


But when i write this ：
<script>
embedpano({swf:"viewer/krpano.swf", xml:"tour-cross.xml", target:"pano", html5:"prefer", passQueryParameters:true});
</script>
into my HTML code，the polygon hotspot can't show in the pano

when i write this：
<script>
embedpano({swf:"viewer/krpano.swf", xml:"tour-cross.xml", target:"pano", flash:"prefer", passQueryParameters:true});
</script>
into my HTML code，the polygon hotspots can show in the pano
why?
here is the way i added polygon hotspots;

<hotspot name="length"
keep="false"
visible="true"
enabled="true"
handcursor="true"
capture="true"
blendmode="normal"
alpha="1.0"
autoalpha="false"
fillcolor="0xFF0000"
fillalpha="0.5"
borderwidth="3.0"
bordercolor="0xFF0000"
borderalpha="1.0"
z-index="20"
onclick="aaaa()"
>
<point ath="0" atv="0" />
<point ath="30" atv="30" />

</hotspot>

If polygon hotspots are supported for html5 in 1.18 version ,why i can't add the polygon hotspots on my pano which is prefer for html5?

ps: my KRpano version is 1.18.

thank for reading ,my english is poor.

any help please?

Quoted from "sachagriffin"

You need more than two points for html5.

Also you should use krpano 1.19 - Pre Release 2 instead since it's not quite backwards compatible and you'll have to upgrade anyway.

Thank you for reply.

Are two points can't show for html5 ? because two points can show for flash.

And you mean that krpano 1.19 is supports polygon hotspots for html5 ?

I tried krpano 1.18.4 ,it still not work.

But an example shows that it should be work

I know it's about 2:00 in USA,thank you a lot!

Right. It's a known issue. Maybe fixed in the future. Use three points or fake your line with four points close.

Yes, it also works, but 1.19 has a better parser. More complex code can be created and some actions/coding styles fail in the new parser.. so just use the new one anyway.
