I'm following the calculations exposed at https://krpano.com/forum/wbb/inde…&threadID=11338, generally calculations are correct, but on some cases looks like there's an offset in calculations, like krpano renders an area of the image, so coordinates of the images get shfited vertically.
The while point in image_point.png appears vertically shifted on krpano (krpano_hostspot_position.jpg).
How to solve that ?
