xx World Transform Rotation help needed
« Thread started on: Dec 17th, 2015, 10:23am »

Hi,

I'm trying to rotate a circular JPEG, advancing the rotation by 5 degrees with each press of the DOWN cursor key.

However I'm having trouble getting the circular image to rotate about its centre point, and would dearly appreciate some guidance on this.

My program, and the JPEG, are online at :-

There may well be easier ways than using the world transform call?

TIA,

Andrew

Five minutes after pressing Post I solved it.

How does that work...?
