The Preferences Menu
Description
The Preferences pull-down menu commands allow operators to
customize the various operating interfaces. A checkmark next to
a pull-down menu item indicates that the command is enabled.
Except for default settings and unless otherwise noted, preference
commands do not remain enabled after the RTR-4 imaging
application is exited. Preferences should usually be checked and
set before acquiring images.
Prerequisites
Ensure the RTR-4 imaging application is loaded and running.
Histogram
Equalize
Select this command to make a
nonlinear change to enhance subtle
details in a different way than Auto
Contrast . It automatically adjusts the
brightness of pixels to balance the
number of pixels across the range of
possible brightness values. This can
improve visual interpretation
Rotate Image Select this command to rotate the image
as follows:
• +180 Degrees.
• Flip Left-Right.
• Flip Top-Bottom.
Undo Select this command to step backwards
through previously created images. If a
modification is performed which does not
provide the desired effect the user can
step backward one image by selecting
the Undo item.
Redo Select this command to step forward
through previously generated images. If
the user decides that a previously
“undone” modification is desirable after
all, they may return to this image by
selecting the Redo item.
