Image Windows
An Image Window is the type of Mira view window used to display 2 dimensional images. The image window has different forms, depending upon which toolbars and docking panes are open. Several of these extra command bars are shown in the Image Window below.
The largest component of the Image Window is the Image Bar that appears between the window caption and the displayed image. This extravagant toolbar puts many image controls and image information near at hand without requiring you to shift your visual focus far from the Image.
The Image Window contains numerous accelerator keys as shortcuts to menu commands. In addition, several single-press Image Keys Pane perform measurements, plots, and other operations on the current image or Image Set.
The Image Keys Pane provides short help and enables execution of all keystroke commands for the Image Window.
Accelerators in the table below execute menu commands when an Image Window has focus.

The Image Window provides several keystrokes for creating plots, making measurements, and performing other commands. These commands work with the Image Cursor (not the window pointer) and are not case sensitive. These single keystrokes do not use a prefix, such as Ctrl or Alt. An image is active for keystroke command input when it has the keyboard focus and the mouse pointer hovers over it. For tips on using these commands, see the notes following the table in the topic Image Keys Pane.
|
Single Keystroke Commands for the Image Window |
|
|
A |
Perform Alignment of the image set by computing a centroid position on the point near the center of the image cursor. The alignment uses horizontal and vertical translation. This works best when the images are already within about 10 pixels of alignment. |
|
C |
Measure the Centroid position near the center of the image cursor. |
|
F |
Measure the FWHM (full width at half maximum about the center of the image cursor. |
|
H |
Create a Row Profile Plot (Horizontal plot) of the row at the center of the image cursor. |
|
I |
Create a Histogram Plot of the region inside the image cursor area. |
|
P |
Opens (or close) the Pixel Table showing values around the center of the cursor. Right click on the pixel table to see its options. The pixel table updates when you wither move the image cursor or cycles between the images of an image set. |
|
R |
Plot a Radial Profile around the centroid position near the center of the image cursor. |
|
S |
Calculate Statistics for all pixels inside the image cursor. The type of statistic is selected in the Statistics Properties dialog described above. |
|
V |
Create a Column Profile Plot (Vertical Plot) of the column at the center of the image cursor. |
|
< |
Move the image cursor left. Hold the Shift key to step 16 pixels. |
|
> |
Move the image cursor right. Hold the Shift key to step 16 pixels. |
|
^ |
Move the image cursor up. Hold the Shift key to step 16 pixels. |
|
v |
Move the image cursor down. Hold the Shift key to step 16 pixels. |
|
+ (or =) |
Magnify the image 2 times, centered on the Image Cursor. |
|
– (or _) |
De-magnify the image by 2 times, centered on the Image Cursor. |
|
|

Several additional keystrokes that are not command accelerators are recognized by image windows. These require the window to have the keyboard focus.
|
[Shift] + Mouse click |
Move the image cursor to the target point, regardless of the current command mode. |
|
[Tab] |
Advance to the next member of the image set. |
|
[Shift] + [Tab] |
Step backward to the previous member of the image set. |
|
Arrow Keys |
