By cropping your Target contact, you can work with a small part of your image
just as easily as you can work with the whole image. Enhance has a built-in tool
for doing that.
To crop a part of a Target image and preview it in Enhance
1. Click in the Target image to make Target your active window.
2. From Target’s main menu, click on
Enhance to open the Enhance
dialog box.
3. Because you will be “drawing” a square around your area of interest,
visualize a corner of the area of interest to you in the Target contact
and put your insertion point there.
4. In the larger, original image (in other words, outside the Enhance
dialog box) press and hold the right trackball button.
5. While continuing to hold and press the right trackball button, use the
trackball to move your insertion point to an imaginary corner opposite
your current position.
6. Release the right button.
The system outlines the area you have cropped with a white square. This
cropped image now occupies all of the thumbnail area in the Enhance dialog box.
You can now make one or more enhancements to the cropped image in
Enhance.
To uncrop a cropped image appearing in Enhance
Right-click in the Target contact image.
The system displays a thumbnail of the entire Target contact image (with or
without enhancements) in the Enhance dialog box.
E.6 Target’s Window Menu
You use Target’s Window menu (Figure E-11 on page 100) to resize the images
in your Target windows and to reposition the windows themselves, as desired.
