How do I make a slide background spin from a central pivot point
Hi Boss,
Couple of things... 1. Please take off the caps lock. It is considered to be shouting on the internet. 2. You do not want the background to spin, you want a full frame image to spin. 3. That spinning image must be large enough to fill the entire frame of the slide, even when it is turned to any possible angle 4. To do this effect a. Insert a starfield image (make sure Polaris is near the center) b. Enlarge it so that it will cover the slide (no matter which angle is being displayed) c. Select the image d. Add a Spin Emphasis animation e. Adjust the time it should take to spin for your presentation f. Make it start with previous, so that you don't have to click anything Additional instructions require knowing what version of PowerPoint you are using and the file properties size of the slides Bill Dilworth "OLDBOSS" wrote in message ...

How do I make a slide background spin from a central pivot point
The math behind this is pretty straight forward geometry.
a = 1/2 of the slide height b = 1/2 of the slide width c = SQR( (a^2) + (b^2) ) ... the longest distance from the center of the slide - special nod to Pythagoras) To get the ratio (%*100) of enlargement over a full slide image needed to keep from showing the background of the slide, divide c by the smaller of a or b. If you are using a 7.5 by 10" slide (standard default), the answer is 166.66% enlargement OVER a full slide sized image. (or 12.5" by 16.65") Bill "Bill Dilworth" wrote in message ...
