Last week, Dave mentioned that you can change the file type used system-wide for screenshots. However, some people are afraid of using Terminal.app to muck around with their Mac. In this week's AppleScript article, I am going to show you how to take screenshots and change their file type using an AppleScript.
property N : 0
set N to N + 1
set picPath to ((POSIX path of (path to desktop)) & "Picture_" & N & ".png") as string
do shell script "screencapture -tjpg " & quoted form of picPath
Using the AppleScript
Open the ScriptEditor (/Applications/AppleScript/ScriptEditor.app). Copy/paste the AppleScript into the script edtitor and click the run button at the top. You will hear the camera shutter sound and a picture will be taken and saved to your desktop.
This script comes in handy when you want to take a screenshot in a different format. To do this, just change the ".png" file type to whatever you might want (say, .jpg, .tiff, etc.). When you re-run the script, the new file type will be associated with the capture image.
