Viewing and Editing Images
12-9
Note: Note that 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 on 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.
Fig. 12-6. Selecting images to display in the viewer.
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.
