Question

When we rotate any object like Image then its x and y will also change according to the

roation angle.

I just want to know how we can calculate the outer rectangle x and y ( pointed with red

circle in the image ) while rotating the image. We have image width, height and

rotation angle ?

Answer 1

x – your x coordinate

height – height of your image

angle – rotation angle

Then you need (x – height * sin(angle))
