Hi,
It seems that, when the 2 attributes are defined inside the <view> node, maxpixelzoom has the priority....
But, if the fovmin attribute is changed dynamically using set(view.fovmin,1) then the fovmin has the priority....
right - when "maxpixelzoom" is set, it has (always) priority

to disable "maxpixelzoom" set it to "0" or to an invalid value ("null" or any "text")
and also right - when dynamically using set(view.fovmin,1) the new fovmin will work, but only for the moment!
when resizing the viewing window (e.g. when resizing the browser window or when switching to fullscreen), then the "maxpixelzoom" setting will work again,
internally it works like this:
when "maxpixelzoom" is set, the "fovmin" will be calculated automatically depending on the window size and the resolution of the panoramic image, and on any change of these both 'parameters' it will update and calculate the "fovmin" value again,
best regards,
Klaus
