Launching Script Editor
Locate the AppleScript folder and open Script Editor. Choose File >
Open Script. Search for the Canvas folder and then the Scripts sub-
folder. Within the Scripts subfolder, open the script entitled Down-
sample. The script will appear in the bottom pane of the Script Editor.
The first line of the script indicates its purpose:
-- This script will downsample a file con-
taining a high resolution image to 72.
In AppleScript, a command or a set of commands for a specific appli-
cation begins with the word tell and ends with end tell.
The first command launches Canvas and opens a new illustration file:
tell application "Canvas 8"
make new document with properties {document
type:illustration}
end tell
The next command launches Finder so you can select the source and
destination folders. Also, the number of files in the source folder are
counted:
tell application "Finder"
set myFolder to choose folder with prompt
"Select source folder:"
set myResults to choose folder with prompt
"Select destination folder:"
set nFiles to count folder myFolder each
file
end tell
The following command begins with repeat since it is to be repeated
on each file that is found in the source folder.
This command indicates that Canvas is to open each image file in the
source folder, set the image resolution to 72 ppi, rename the file, and
save it to the destination directory.
repeat with i from 1 to nFiles
tell application "Finder"
set f to file i of myFolder
set fName to get name of f
end tell
tell application "Canvas 8"
