 One common graphics use would be to prevent scanning above or below a certain point. For example, lets say that you were projecting laser graphics over a standard television screen with a 4:3 aspect ratio. Since the laser typically has a 1:1 aspect ratio, this would mean that the graphics could possibly scan above the top or below the bottom of the screen. You can use the **Beam Attenuation Map** to make sure that the brightness at the top and bottom of the screen is zero. One common graphics use would be to prevent scanning above or below a certain point.

 Another common use would be to reduce the brightness below the horizon to a level that would be more pleasing for audience scanning viewers. This can easily be done by selecting a reduced brightness level, and filling the rectangular area below the horizon. Another common use would be to reduce the brightness below the horizon to a level that would be more pleasing for audience scanning viewers.

 Another common use would be to protect certain areas from hazardous laser exposure or to reduce the brightness in certain areas. When doing beam shows outdoors, it is often necessary to ensure certain areas (such as the windows in certain buildings) won’t be exposed. Using the rudimentary drawing tools, it is possible to "carve out" areas from the projected area. Another common use would be to protect certain areas from hazardous laser exposure or to reduce the brightness in certain areas.

 The **Minimum number of points** setting in the **Projector Settings** window can be adjusted to relieve the scanners from trying to scan high duty-cycle images that might cause power limiting. Setting the **Minimum number of points** to 200 or higher can actually increase the life of your scanners. However, doing so will mean that if you project less than 200 points, the additional points will be blanked. For beam frames, it is often undesirable to have any unintended blanking at all because such blanking would tend to reduce the power of the display. When the **Prevent minimum number of points** check box is checked, all scanner output will be dedicated strictly to producing laser output and the Minimum number of points setting is ignored.  The **Minimum number of points** setting in the **Projector Settings** window can be adjusted to relieve the scanners from trying to scan high duty-cycle images that might cause power limiting.
