Keystone Correction Parameters
When an image is output from a
DL.2 fixture at an angle the image
may appear skewed. Eight
Keystone parameters adjust the
image shape and compensate for
this effect. You can control each of
the four corners of the graphics
output to reshape your image to a
form that projects correctly.
Default DMX Value: 0 = no
keystone correction has been
applied
Each corner has an x and a y value that adjust and correct scale of the projection from any
corner toward the image center on that axis.
Setting all Keystone X and Y parameters DMX values to zero will place the four corners of the
image at the four corners of the projector output. Adjusting keystone x values toward 255
(100%) moves the respective corner x positions horizontally toward the center of that image
edge. Adjusting keystone y values toward 255 (100%) causes the respective corner y positions
to be moved vertically toward the center of that edge of the image.
Tip: These parameters can also be used to create interesting skewing as a design effect.
