I want to do this : selecting a zone in a video by clicking it, i want to zoom considering the click point as the CENTER of my zone.

- calculate the size of zoomed screen related to zoom (resolution / zoom) for x / y

I want to do this : selecting a zone in a video by clicking it, i want to zoom considering the click point as the CENTER of my zone.
So, my weak sense of logic would be :
- calculate the size of zoomed screen related to zoom (resolution / zoom) for x / y
- to get the center point, substract 1/2 of that new x value and add 1/2 of the y value

Here's an example of centering the zoomed image. Adjust as needed to center around your mouse click.

A pretty old thread, but I've just had the same question :D

My further question would be, that keeping the center-zoom feature, can you also move the image to left and right somehow?

I've tried to do it with the offsets, but it did not work :(

Hi! Change the position first, then use jit.rota to do the rotation, scaling, etc.
