Hi,
I'm a longtime very happy krpano user, but never posted on the forums before.
I have a 360 degree cylindrical gigapixel. The image size is 250,000 x 50,000 pixels in cylindrical projection. I want to know how to calculate the pixel position of my image to ath, atv of a polygon hotspot.
For example, I know that if x = 125,000, and y = 25,000 then I should get ath = 0 and atv = 0.
But how do I calculate it for other positions? Like say what is the ath and atv of x = 50,000 and y = 40,000?
I want to do this but with a cylindrical pano: http://www.krpano.com/forum/wbb/inde…49963#post49963
