Expand
(radio buttons)
Just as you can expand or reduce an image in Target, so can
you expand (zoom in) or reduce (zoom out) on an image from
the Enhance dialog box. In Enhance, zooming can take one of
three forms: replicate, bilinear, or cubic.
•
Replicate: The image is interpolated and magnified
linearly. Original pixels values are replicated.
•
Bilinear: This kind of zooming takes into consideration
a 2x2 neighborhood of pixels about a point.
•
Cubic: This kind of zooming takes into consideration a
4x4 neighborhood of pixels about a point.
Apply to
large image
(button)
The current set of enhancements you did on the thumbnail
image is applied to the image you loaded into Target.
Undo large
image
(button)
Undo large image undoes all enhancements to both the
thumbnail image and the Target contact image done in this
session. However, because Undo large image does not
remove the unenhanced thumbnail image from the thumbnail
viewing area, you can use the current thumbnail image (now
cleared of enhancements) as the template upon which you can
impose a new set of enhancements.
Undo large image does
not uncrop a cropped image (right-click in the Target contact
image to do that). Compare to Undo All earlier in this table.
Close
(button)
Exits the Enhance utility but not the Target utility.
