Blink

Blink switches through the images shown in a channel at a rate chosen by the user. Alternatively, it can switch between channels in the main workspace. In both cases, the primary purpose is to compare and contrast the images (within a channel, or across channels) visually within a short timescale – like blinking your eyes.

Plugin Type: Local or Global

Blink can be invoked either as a local plugin, in which case it cycles through the images in the channel, or as a global plugin, in which case it cycles through the channels.

Local plugins are started from the “Operations” button, while global plugins are started from the “Plugins” menu.

Usage

Set the interval between image changes in terms of seconds in the box labeled “Interval”. Then, press “Start Blink” to start the timed cycling, and “Stop Blink” to stop the cycling.

You can change the number in “Interval” and press Enter to dynamically change the cycle time while the cycle is running.

It is customizable using ~/.ginga/plugin_Blink.cfg, where ~ is your HOME directory:

#
# Blink plugin preferences file
#
# Place this in file under ~/.ginga with the name "plugin_Blink.cfg"

# Blink channels instead of images within a channel
# PLEASE NOTE: this option is DEPRECATED
blink_channels = False

# the maximum interval for a blink
interval_max = 30.0

# the minimum interval for a blink
interval_min = 0.25
