Ray,

I had a similar problem and worked my way through to find a solution, then I posted the stack to revOnline, it's not perfect, but it may help, here's the link…

http://livecodeshare.runrev.com/stack/685/Angle-and-Resize-an-Image

…or search for "Angle and Resize an Image" in the User Samples from LC.

Hope it saves you some frustration.

You may wish to add your comments to http://quality.runrev.com/show_bug.cgi?id=9244 and maybe someone will look at the problem again.

Paul

If I set the lockLoc to false I can set the angle to a number of degrees without it getting reduced in size, but then I can't set the width and height.  The other way around (if I set the lockLoc to true) I can then change the width and height after setting the angle, but setting the angle forces a reduction in the size of the image to fit the 'bounding rect' of the image.
