Does anyone know how to rotate an image by 90 degrees without creating

Transcript matrix transform (slowish) is there another way? I don't
fancy lots of imagedata manipulation... I'm sure there is a simple
way.
Currently I'm rotating, grouping and resizing group (brings corners
in). Not good.
Unfortunately there isn't, AFAIK, an option to rotate without enlarge;
the
only solution I have found is to rotate then crop. Using the built-in
rotate, and then 'manually' (ie in a transcript function) cropping, is
still
much quicker than writing your own rorate code (at least, with my
attempt!).
Depending on your needs, you can write your own crop routine now
(remember -
using 'repeat for each', although more clumsy, is _much_ faster than
'repeat
with'); or wait for Rev 2.0 which has a crop command built in.
take a look at the angle property. This may help a bit.
