2004/08/05: Built into ImageJ 1.33i as Edit/Selection/SpecifySource: Specify_ROI.java Installation: This plugin is built into ImageJ 1.33i or later as the Edit/Selection/Specify command. Description: The user types in a width and height value, and the plugin create a rectangular or oval region of interest based on those values. (Why? Because it can be time-consuming to repeatedly create a ROI of an exact size with the mouse.) Enhanced by Anthony Padua to take slice number and the option to have the x and y coordinates centered or in default top left corner of ROI.

This plugin is especially useful for speeding up the placement of ROIs of particular sizes in particular locations in an image or within a stack. (When multiple ROIs are placed, used of this plugin can be much faster than drawing or positioning these ROIs by mouse).
