Acorn Trim Scripts

These scripts, inspired by Bosco’s Foto Trimmer, make it easy to crop a single row or column of pixels off the edge of an image. This can save you some intricate mouse work and/or manual typing of pixel values to resize the canvas, and it’s especially useful for manipulating screenshots.

Requirements

Acorn 1.0.3 or later.

Installation

Copy the .py files into the folder:

~/Library/Application Support/Acorn/Plug-Ins/

Usage

The trim commands should show up in the Filter menu. It’s easiest to invoke them using the keyboard shortcuts:

Trim Top
Command-Control-W
Trim Left
Command-Control-A
Trim Right
Command-Control-D
Trim Bottom
Command-Control-S

If you trim off too much, just use Edit ‣ Undo (Command-Z).
