Proportional Scaling of non-EPS images in RR ?

[Mark Smith]

Richmond, this should work, I think:

on scalePic pImg
   put min(the height of this stack / the height of pImg, the width  
of this stack / the width of img pImg) into tFactor
   set the height of img pImg to the height of img pImg * tFactor
   set the width of img pImg to the width of img pImg * tFactor
   set the top of img pImg to 0
   set the left of img pImg to 0
end scalePic

Best,

Mark
