Select #!F-adobe-times-bold-r-normal--18* Zoom #!EF in the #!F-adobe-times-bold-r-normal--18* Mode #!EF option list of the dialog box. #!N #!I30 #!N 2. To zoom in, position the mouse cursor in the Image window and hold down the #!F-adobe-times-medium-i-normal--18* left #!EF mouse button. An overlay rectangle appears. #!N #!I30 #!N 3. You can enlarge or shrink this rectangle by moving the mouse cursor away from or toward the center of the window. #!N #!I30 #!N 4. When you release the mouse button, the area of the rectangle expands to fill the Image window, making the object appear nearer. Note: If you simply click the mouse button instead of holding it down, the overlay rectangle will disappear before you can change its dimensions. The modified image of the object will be based on that rectangle. (The size of the rectangle and thus the degree of "zoom" depends on the distance of the cursor from the center of the window when you first press the mouse button.) #!N #!I30 #!N 5. To cancel the effect of the most recent command, select #!F-adobe-times-bold-r-normal--18* Undo #!EF in the dialog box or in the #!F-adobe-times-bold-r-normal--18* Options #!EF pull-down menu. You can also repeat a command that has been "undone," by selecting #!F-adobe-times-bold-r-normal--18* Redo #!EF . Note: Since executed commands are maintained in a stack, you can undo those commands one by one and redo them, too. #!N #!I30 #!N 6. #!F-adobe-times-bold-r-normal--18* Reset #!EF in the dialog box (or in the #!F-adobe-times-bold-r-normal--18* Options #!EF pull-down) menu restores the original #!F-adobe-times-medium-i-normal--18* view: #!EF (e.g., front) of the object. #!N #!I0 #!N #!EF #!N #!F-adobe-times-bold-r-normal--18* Zooming out: #!EF #!N #!I0 #!N #!F-adobe-times-medium-r-normal--18* #!N #!N #!I30 #!N 1.

When you release the mouse button, the area of the Image window is reduced to the area of the rectangle, making the object appear more "distant." #!N #!I0 #!N #!EF #!N #!F-adobe-times-bold-r-normal--18* Panning and Zooming out: #!EF #!N #!I0 #!N #!F-adobe-times-medium-r-normal--18* #!N #!N #!I30 #!N 1.
