I found way; it seems convoluted to me. I create an image, store in
width/height to a field....
on mouseup.
# on palette/ utilities stack/ for some reason selectedImage() won't work
try
put the long id of the selectedObject into sImage
end try
if sImage is empty then
Answer "You need to select an image" with "OK"
exit to top
end if
put the long id of the selectedObject into sImage
if fld "DefaultImagePath" is empty then put the long id of the
selectedObject into sImage
if fld "DefaultImagePath" is empty then
answer file "Select the image you wish to view:" with type "JPEG
Images|jpg|JPEG"
if it is "Cancel" then
exit to top
else
put it into tFilename
put tFilename into fld "DefaultImagePath"
create image
put it into tNewImage
set the loc of tnewImage to -1000,-1000
set the filename tnewImage to tFileName
set the filename of sImage to fld "DefaultImagePath"
put (the width of tnewImage)& comma & (the height of tnewImage)into
field "originalSize"
delete tNewImage
end if
else
set width of sImage to item 1 of field "originalSize"
set height of sImage to item 2 of field "originalSize"
end if
end mouseup

Well after all these years, I want to know the original width and height of
a referenced image by its "content" and not by its "image data" which will
change if the image was resized. So let's say it is referenced brand new image:
answer file "Select the image you wish to view:" with type "JPEG
Images|jpg|JPEG"
# the filename of an image to that. Let say its 250 X 150 pixels
# resize this image to something "stupid" like 100 x100
How does one query, at that point in time, the original height and width?
I looked through to dictionary, and don't see a way. In course of the
mini-study I found "prepare"
on mouseup
answer file "Select the image you wish to view:" with type "JPEG
Images|jpg|JPEG"
if it is "Cancel" then
exit to top
else
put it into tFileName
end if
prepare image file tFileName
put the width of image file tFilename # error here
end mouseup
This entry seems a little lean....
prepare
"...Then access the image and display it as needed on your stack. Since the
image is already cached into memory, it displays instantly."
One would think that since it is cached, you can get its rect?
What am missing? Do have to create a new image to get its original size?
===========
The location and name of the image file you want to load and
decompress into the image data cache. Since the image data cache is
keyed on the absolute filename, any images which reference that file
are able to use the data from the cache. This assumes that the cache has
not been flushed.
Description
Use the prepare image command to speed up execution when
showing image data.
Use the prepare image command to preload an image at some time
before it is needed. Then access the image and display it as needed on
your stack. Since the image is already cached into memory, it displays
instantly.
