5.Tools
The Tools section allows you to examine the image data a number of ways. You can examine the image
header information, magnify close up sections of the image, view brightness distribution or examine
individual pixels.
All of the functions in the Tool menu are for analysis and do not affect only the image display, or image
data.
To access the commands you can either click on Tools on the Menu Bar with the mouse, use the Alt key
and the appropriate underlined letter from the keyboard, or, when available, click on the appropriate button
from the Tool Bar.
Descriptions of the Tool commands from the Menu Bar appear below. The icon from the appropriate
button from the Tool Bar also appears next to the description for your reference.
Coordinates
The Coordinates function displays a modeless dialog box that continuously shows the current
coordinates of the cursor while it is positioned over the image. The value of the pixel under the cursor is
also displayed and is updated as the cursor moves.
The pixel value may be displayed in three different formats: the 8 bit integer display value, the scaled
floating point value or the 16 bit unprocessed value. The 16 bit format is only available for 12 or 16 bit
images when the 16 bit data is resident. The mode can be chosen by selecting either the Integer, Real,
or Unprocessed button located at the bottom of the dialog box. See the Image Prescale function for
details on keeping the 16 bit data resident.
The coordinate dialog box must be active if you wish to make distance measurements from the image.
The Dist. field will display the distance value after the Set Distance Ref. function has been selected from
the Image Utilities dialog box.
Histogram
Displays a bar graph of the number of pixels in each of the 256 colors or shades of gray. The graph is
automatically scaled, and displayed in a logarithmic format.
The Max field at the top of the display indicates the maximum number of pixels contained in any of the
colors. The background grid is logarithmically scaled. The lower group of 10 lines indicate the values
from 1 to 10, the next group indicate the range from 10 to 100, the next group is 100 to 1000, and so on.
The histogram is automatically updated whenever the image values have been modified.
Magnifier
The Magnifier allows you to zoom into any portion of the display to observe small details. If an image is
displayed when the magnifier is turned on, the default starting location is the center of the image,
otherwise it uses the center of the client area of the main window. A new area can be selected by moving
the cursor onto the magnifier's
window, depressing the left mouse button, then, while still holding the left button, move to the desired
area.
The magnification factor can be changed by moving the scroll bar located on the right side of the magnifier
window. The magnification range is 1.0 to 32.0 in steps of 0.1. The default magnification is 4.0.
The size and location of the magnifier window can be modified using the standard methods.
