4.4 Show Loaded Images
The show function allows the user to select which plane numbers or saved
image combinations
are to be displayed in the red, green, and blue channels or to
select which plane number is to be displayed as a black and
white image. To view a color composite image, use the mouse to select a single plane number from each plane list (i.e., one for
the red, one for the green, and one for the blue channel) and press the
accept button. If only 2 image planes are selected, the third will
be a duplicate of one of the selected planes. To view a black and white
(i.e., gray scale image), select only one plane number from any plane list
or select the same plane number in all three lists and press the accept
button.
The image data loaded into the selected plane will be displayed in black
and white.
The Show function also allows the user to obtain information about the
image data loaded into a particular image plane. By double clicking the
left mouse button on a plane number (from the red, green, or blue plane list),
an image information panel is popped
up which shows the file name the image data was read from, the window that
was loaded, the band number, and the subsampling factor. By double clicking on
a name in the save list, the user can determine which planes were used in the
saved combination.
- Red, Green, and Blue Plane Lists:
- The plane lists show the user a list of plane numbers that
contain valid image data. The user chooses the plane numbers
to be displayed in the associated channels from these lists.
- Save List:
- The list of currently saved band combinations and mappings. To view a
previously saved combination, select the name and press the accept
button. The entry Current is a special entry. Double clicking
on this entry shows the user which planes are currently displayed in
the main image window.
- Save:
- Save the current band combination and mapping with the specified name for
future reference. This save operation is temporary in each session.
- Delete:
- Delete the selected item from the save list. The delete button
is sensitive only when an item has been selected from the save list.
Image data is not deleted; only the reference to the band combination
and mapping is deleted.
- Accept:
- Display the selected planes in the appropriate channels. On 8-bit
displays, displaying a color image with the show function implies the
selected planes must be sent through the color compression algorithm.
-
Name (Save popup):
- Enter the name to be associated with the currently displayed image. The
name is accepted and verified as soon as the user presses enter.
All names are converted to lower case, duplicate names are not allowed, and
there is no restriction on the length of the name.
- Cancel (Save popup):
- Close the Save popup panel without saving the displayed image
combination.
- Dismiss:
- Close the show panel.
