blink: Blink two frames

Package: iis

Usage

blink frame1 frame2 [frame3 [frame4]]

Parameters

frame1
First frame in blink sequence.
frame2
Second frame in blink sequence.
frame3
Third frame in blink sequence.
frame4
Fourth frame in blink sequence.
rate = 1.
Blink rate in seconds per frame. May be any fraction of a second.

Description

Two or more frames are alternately displayed on the image display monitor ("stdimage") at a specified rate per frame.

Examples

To blink two frames:

cl> blink 1 2

To blink three frames at a rate of 2 seconds per frame:

cl> blink 3 1 2 rate=2

Bugs

The blink rate is measured in software and, therefore, will not be exactly even in a time sharing environment.
