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.
