image rotation

[jurij]

I'm triing to rotate an image around a certain point in image, that is not necessarily a center point. What would be the best (simplest/fastest solution).

I wanted to use imrotate, but it seems it rotates only around a center point. I tried to modify it, but I had no luck :]

I also tried to write my own image rotation function. It worked but it was slooooooow :].

Thank you!

cant you just translate the equations to make the rotation point the origin in the new frame?

Can't you copy the image into a larger array with the offset desired, rotate and crop to size?
