David & Ken --
Thanks for your assistance. It was failing to lock the size/loc of the
new image that was tripping me up.

Just from memory - you need to set the rect of the image to the nuew
thumbnail size and let rev do the scaling for you... then you can
get the
imagedata which returns the scaled image data and set the imagedata
(ie set
the imagedata of image "thumbnai"l to the imagedata of image
"thumbnail")
But looking at your script - I don;t think you need to do any of
that - you
just need to:
put image "mDisplay" of stack "dispStack" into img "mThumb" of group
newGpName of stack ".....
and make sure the thumbnail image has its location locked. Then you
can:
set the imagedata of image "thumbnail" to the imagedata of image
"thumbnail"
if you want to scale down the new image size.

I'm trying to make a thumbnail from a snapshot of an image from
another
substack. First I clone a group that contains a thumbnail image and
a text
field, then I reposition the new group, then I try to get a new
thumbnail
into the new group. Here's what I've tried (partial script):
clone group "imgItem 1"
set the name of it to newGpName
-- newGpName is already constructed, it is "imgItem k" for some k
-- now set location of new group
set the top of group newGpName to 30
set the left of group newGpName to the left of group "imgItem 1"
-- store the new rect of the thumbnail, then delete it
put the rect of img "mThumb" of group newGpName into thumbRect
delete img "mThumb" of group newGpName
-- import new image into cloned group (last group)
start editing group newGpName
import snapshot from image "mDisplay" of stack "dispStack"
-- rename image
set the name of last image to "mThumb"
stop editing background newGpName
-- resize image to thumbnail size and location
set the rect of img "mThumb" of group newGpName to thumbRect
What I get is not a properly sized thumbnail -- I get an image that
looks
the size of the whole new (cloned) group, and it's not a miniature
of the
big image, it's a crop of the big image. I can't remember how to
miniaturize
an imported snapshot down to thumbnail size. I know this has been
discussed
before but can't find it in the gmane archives. Any help appreciated.
