changing image resolution

[robert.k]

Dear all,

I have a question and I really hope someone might have a answer for me.

Currently I am developing an image database for fm6. every record should know about 2 kind of images - high resolution and low resolution. I am storing those files on a central place with the help of trois file plug in.

what I love to do is that the user does not need to create 2 different images - instead filemaker can create out of the high res image a second one (the low res image).

is there any plug in out there? so far I have tried a combination between the scripting possibilities photoshop and apple script but I would love not using photoshop for this task.

does someone has an idea?

cheers

robert

There is a built-in application in OS X, Image Events. Look at its dictionary. The following will resize an image file, that you choose. This simple script is modifying the original chosen; so in real life you'd want that to either be a duplicate of the original file, or to save the result in another file, ie., in file specification "file path".

set this_item to (choose file) as file specification

tell application "Image Events"

launch

set this_image to open this_item

scale this_image to size 128

save this_image as JPEG -- with icon

close this_image

end tell

--This will do it by a factor:

set this_item to (choose file) as file specification

tell application "Image Events"

launch

set this_image to open this_item

scale this_image by factor 0.25

save this_image as JPEG with icon

close this_image

end tell
