interactive area troubles

Hello,

I made the tutorial about interactive area but I have some troubles with the calculations.

I can't put my hotspot image on the exact location..

In this tutorial folowing calculations are made

hotspot.width = 583 * 1000 / 1900 = 306.842105
hotspot.height = 332 * 1000 / 1900 = 174.736842
hotspot.ox = 662 * 1000 / 1900 - 500 = -172.631578
hotspot.oy = 941 * 1000 / 1900 - 500 = -4.736842

But when I recalculate the hotspot.ox my result is = 662 * 1000 / 1900 - 500 = -151.578947

What's wrong here. ??

In my test it looks like this "hotspot.ox coordinate" causes the problem..

Thanks for any help.

Hello,

Thanks for your reaction !

And I found my own mistake as well..
I switched the x and y values and that was the reason why it didn't match...

Cheers,
