Scale
You can magnify or reduce the composite image size using the Scale Parameter.
Default DMX Value: 128 (50%) = Normal Scale
The Scale parameter adjusts the size of the composite image up to approximately 10x its
original size. At a DMX value of zero, the image shrinks to the minimum size. At the midpoint of
the DMX value range, the image is normal size. When the DMX value is increased from the
midpoint, the image is enlarged to the maximum at a value of 255 (100%).
Note: Each image layer has a Scale parameter that lets you scale a layer individually.
See Scale Parameter on page 62 for a graphic that illustrates the Scale effect.
Rotate
The global Rotation parameter controls the composite image rotation up to 360° around the
Z axis. This parameter does not override rotation setting for the individual image layers but
adds to it.
Default DMX Value: 0 = no rotation
DMX values between 0 and 128 (50%) control indexed rotation from 0° - 360°. At 128 (50%),
rotation stops. When the DMX value is greater than the 128 (50%), the image begins rotating
continuously. DMX values from 128 (50%) to 191 (75%) decrease the speed of continuous
clockwise rotation. A DMX value = 191 stops rotation and values from 191 (75%) to 255
(100%) increase continuous rotation speed in a counterclockwise direction.
Tip : If you want to index the rotation counterclockwise, set the starting DMX value = 128
(50%) and move toward zero.
