Viewing and Editing Images
3-17
Note: The color channel used to display an image in the viewer has no relation to the
filter used when capturing the image. The red, green, and blue channels are
simply designed to distinguish different images.
The image name is displayed in the Red name field at the top of the viewer, and the
Red Channel checkbox will appear selected.
To add another image, make sure the image is open and click the pulldown button
next to the Green or Blue name field. Select the image name from the pulldown list.
Add a third image using the same procedure.
You can reassign the different images to different channels using the pulldown
buttons to the right of the name fields. Select <clear> from the pulldown list to
remove an image from that channel of the viewer.
Viewing Options
To remove a particular color channel from the display, click in the checkbox
associated with that channel to deselect it.
Selecting the Auto-Scale Image When Assigned checkbox will automatically adjust
the brightness and contrast of each loaded image based on the data range in the image.
It invokes the Auto-Scale command from the Transform window when an image is
first opened in the viewer. Note that this setting affects only how the image is
displayed in the viewer, not the actual data.
Note: If you deselect this checkbox, any images currently displayed will remain auto-
scaled. click the Transform button in the viewer and click the Reset button in the
Transform window to undo auto-scaling.
Buttons for various viewing tools are included in the Multi-channel viewer.
Commands such as Zoom Box and Grab will change the display of all the images in
the viewer at once.
Note that if you open the Transform window, you can adjust the display of each
channel independently, by selecting the appropriate channel option button in the
Transform window. Similarly, the Plot Cross-Section command will report the
intensity of each channel separately.
