Cropping (修剪) an Image With the Snap Shot Program

Welcome to the world of photo-editing!

Cropping an image allows you to zero in on (对准，聚焦) just the portion that is important to your project. For example, you may want to insert an image of a covered train in a report but may not want to include the whole train. Cropping the image allows you to select only the small area you wish to retain (保留) and eliminate all other portions of the original picture.

Option 1: Cropping by Placing the Image in a Shape

Screen Shot 1

Using one of Snap Shot’s standard shapes as a photo-editing tool requires no special abilities. To crop an image with a standard shape:

a. Click Cropping & Orientation from the Effects menu.

b. Click to select one of the six shapes to frame your image.

c. Use the mouse pointer to draw a frame around the portion of the image you wish to retain. Re-size the frame by dragging the shape’s sizing handles. When you are satisfied with the results, click Cut It.

d. Snap Shot will automatically return to the project that is open. (You may also copy or cut the cropped image and paste it into another application.)

Option 2: Freehand Cropping of an Image

a. Click Freehand Crop from the Cropping & Orientation option on the Effects menu.
