Hi Klaus,
I'm building a snapshot plugin for krpano with WebGl and preserveDrawingBuffer and it works great !
I only have one issue on my iPad 2, if I take the screenshot before all the tiles are loaded then it works as expected, but if I take the snapshot when all the tiles are loaded then I only have a blackscreen instead, like if the drawing buffer was empty ?
Tested on iphone it works great too, no issue on android, for now only my iPad 2 have this problem...
Do you have a clue ?
here is the demo : https://www.360images.fr/krpano_snapshot/
thanx !!!
