Background Task

Author: Wayne Rasband (
Requirements:Requires ImageJ 1.19h or later.
Installation: Copy Background_Task.class to the plugins folder and restart ImageJ.
Description: This plugin illustrates how to do time-consumming backround processing in ImageJ. What it does is fill a 60x600 image at the rate of one pixel per second, taking 10 hours to complete the task. Close the window to abort processing. After 10 hours, each missing pixel in the image represents a second when the plugin did not get any processing time.
