screen capture sizing

I am a novice to this game but cannot find any information to help me with the following problem. I have a script to do a screen capture, but want to capture a specific size (as in “screen capture -i” in the cli). Can I script the actual location and size of the screen I want to capture, rather than do it interactively, noting that the size is smaller than a specific window?

Model: PowerBook G4
AppleScript: 1.9.3
Browser: Safari 312
Operating System: Mac OS X (10.3.9)

There’s no support in the screencapture command line options to set size or position of the area to capture.

Given that screencapture itself can’t do it, there’s not much chance of you doing it via AppleScript.

Thanks for the response Camelot. I was hoiping there was some hidden extras in screencapture that I had not tracked down… I can always capture the window and crop later I guess. I appreciate you responding in any case.
