Hi,
I think I have found an error in the documentation on the presentation of the events.add function here: https://krpano.com/docu/xml/#events.dynamicevents
There is a reversal in the parameters.
It reads: events.add(events, callback, name)
Whereas it should read: events.add(name, events, callback)
I continued my tests.
When cropping with an SVG source, no issues, but that seems logical!
Hello klaus.krpano ,
With 1.23.2, my goal is to ship UI assets 300% for smartphones with high devicePixelRatio, then downscale them in krpano on other device.
This works fine on without crop (smooth downsampling), but as soon as I use crop, the downsampling becomes unsmoothed, producing jagged edges.
Exemple with scale 100% , 25%, 12.5%
Thanks ;)
Thanks for this great update ! 
I'd like to take the opportunity of the topic on image quality to ask if you've done any tests on the use of webp instead of jpg (which seems to be supported by everyone now)?
I've noticed some weight savings for equivalent quality
I don't actually use it much.
It's really specific to VR headset use, and that's not often how my customers use it.
The gain in image immersion remains limited, and customers aren't necessarily willing to pay for this feature.
Yes, the treatment is not seamless.
But 90% of the work is done, and I send the image twice, shifting it to process the seam.
I tested immersity.ai
It met my client's expectations in terms of quality, and saved me a lot of time on his request for stereoscopy for his VR headset.

Thanks for your quick reply!
I didn't know about this technique for using hotspot attributes on a layer.
If I understand Javascript correctly, you create a hotspot in a layer?
I'm still not comfortable with Javascript, but you're saying that you can use the alphachannel attribute (TB or SBS) on a layer with this method?
I just need to add hs.alphachannel = SBS (for example) under the var hs?
Hello everyone,
I'm looking for available solutions to have videos with alpha channel (transparency), especially for layers.
Not having the “alphachannel” functionality of hotspots and not having webm support with alpha on Apple hardware (at least on iOs/safari), have you identified any other method?
I've read about h265 with alpha, but that can only be encoded on MacOs! And I haven't looked into the compatibility of this format
Thx ;)
How many ksplats do you have in your scene ?
StorySplat's solution sounds like a good viewer.
I did a few outdoor tests a few weeks ago, now I just have to manage the file size.

Hello group!
I'm here to introduce you to my latest 360° virtual tour project using KrPano.
Take a behind-the-scenes tour of France Télévisions and discover the France2 news sets, Franceinfo studios, Télématin set, control rooms and much more!
It's a very popular format at the moment, and it's evolving fast!
It would be very useful to be able to support this format in KrPano, with good management of data streaming, which can be very heavy.
I'm not familiar with the engine used by the FIGLIE project and I don't know of any self-hosted service like KrPano, allowing the display of GS with quality and functionality.
Hello everyone,
Unless I've done some bad research and it's already possible, it might be useful to be able to use the “crop” for layer or hotspot, with percentage values.
For example, to be able to quickly cut an image in 2 (or more), without having to detect its size, for an onovercrop/ondonwcrop
Thx !
It's really very interesting.
I'm also getting into Gaussian Splatting, but via PostShot so that I can be independent of the calculation, but I haven't found an effective viewer for self-hosting.
Have you done any research in this direction?
Maybe with the integration of three.js in the next version of KrPano who knows ;)
I'd never realised it was possible to call any variable as an action in this way.
I haven't seen it documented?
Does anyone else have this problem on a PC?
After opening the URL, then returning to the virtual tour tab, the 360° image turns black as soon as the mouse cursor returns to the browser.
Would you like another example or the xml code to reproduce this?
It's not very annoying, but I tend to use "ondown" instead of "onclick" for smartphones and tablets, it validates the action more easily and prevents nothing happening if the visitor "clicks and drags".
Oh ?
I made a small record :
Same problem with Firefox/Edge without adblock
