Change Pointer Controls
The pointer control buttons (Figure 8-16) change the action of the pointer when it is pressed and dragged
on an image.
Figure 8-16 Pointer control buttons
The pointer controls allow you to perform other functions that are not available in any other tool panel.
Follow this process to change the pointer controls. Table 8-7 describes the action of each control.
1. Select the image to act upon, if necessary.
2. Press the pointer control to use.
3. Press and drag the pointer on the selected image.
Table 8-7 Pointer Controls description

Change Image
Brightness /
Contrast
Changes the brightness and contrast by dragging the pointer instead
of using the Image Display Tools controls.
• Contrast: Press and drag the pointer vertically. Up is more contrast,
down is less contrast.
• Brightness: Press and drag the pointer horizontally. Right is brighter,
left is darker
Moving the pointer diagonally will change both brightness and contrast
in proportion to the angle of movement. That is, if you move the pointer
at a perfect 45° angle, brightness and contrast will change equally;
however, if you move the pointer at a 20° angle (more horizontally) the
brightness will change more than the contrast.
