    We recently deployed krpano HTML5 on a 65" UHD touch tabletop surface. We found that when people zoomed all the way in to an image until they reached the maximum zoom level, but kept spreading their hands/fingers beyond that, the image would stop zooming as it should. However when their hands/fingers were drawn closer together to zoom out, nothing would happen right away, until they'd brought them close enough together to reach the previous zoom-out extent.


    A nicer behavior would be that when fingers/hands are brought closer together, zoom out should always begin, even if the previous gesture took the image beyond the zoom in limit.

    We recently deployed krpano HTML5 on a 65" UHD touch tabletop surface. It technically works fine, but experientially we're finding a difference between how people assume it works on a small screen vs a large screen. On smaller tablet-sized screens, people use one finger per hand to zoom in and out. On the very large screen, we note that people use multiple fingers per hand to zoom in and out, or even their whole hand. krpano behaves strangely when users do this.

    A fix might be a way to ignore multiple fingers which are closer together than some threshold, and treat them as a single finger.

    I'm hoping to use a higher memory.maxmem setting in order to preload more tiles and reduce the appearance of lower-res tiles when zooming. Without changing anything, my Chrome tab with a full-screen pano is using around 200MB. I tried:

    Code
    <memory maxmem="500" devices="Desktop+HTML5"/>
    Code
    <memory maxmem="2048" devices="Desktop+HTML5"/>


    ...but memory usage never increased. Is there a hard-coded cap? Maybe I have to change something in the browser settings to allow usage of more resources?

    When using the HTML5 viewer on a touch device (tested on iPhone and a Windows 7 touch screen), zoom gestures are performed by spreading two fingers apart. On consumer touch devices (iPad, etc), this zoom gesture is used in photos and mapping applications, and the zoom is centered at the midpoint between the two fingers, so that at the end of the zoom you're looking at a crop of the image that you had at the beginning of the zoom. The center of the zoom in the krpano viewer is unclear, and seems to change during the zoom gesture.

    Here is a video of the desired behavior, using a different viewer from krpano:

    It there any way to improve this? We are using the 1.18.5 HTML Viewer.
