Image Tool Keystroke Commands
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.

Image Tool Keystroke Commands |
|
|
a |
Performs Alignment of the images 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 5 to 10 pixels of alignment. See Align on Point. |
|
c |
Measures the Centroid position near the center of the image cursor. See Centroid Measurements. |
|
h |
Creates a Horizontal plot of the row centered on the image cursor. See Row Profile Plot. |
|
i |
Creates a Histogram Plot of the region inside the image cursor area. See Histogram Plot. |
|
p |
Opens or closes 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. See Pixel Table Pane. |
|
r |
Plots a Radial Profile around the centroid position near the center of the image cursor. See Radial Profile Plot. |
|
s |
Calculates Statistics for all pixels inside the image cursor. The type of statistic is selected in the Statistics Properties dialog. |
|
v |
Creates a Vertical Plot of the column centered on the image cursor. See Column Profile Plot. |
|
Left arrow |
Moves the Image Cursor left 1 screen pixel. |
|
Right arrow |
Moves the Image Cursor right 1 screen pixel. |
|
Up arrow |
Moves the Image Cursor up 1 screen pixel. |
|
Down arrow |
Moves the Image Cursor down 1 screen pixel. |
When an Image Set is displayed, the command operates on either the top image or all images, according to the value of the Image Set Flags set using buttons on the Image Bar. Note that the arrow keys continue to move the cursor as usual. For these keystroke commands and the arrow keys to be received by the Image Window, the window interior (the image) must have the keyboard focus. To set the keyboard focus, click on the image without the mouse pointer in a command mode (e.g., not actively marking apertures or measuring points). If the Image Window already has the focus, then the commands are active when the mouse pointer hovers over it.
