Screen Coordinates
The Kayenne XL Package Digital Picture Manipulator accommodates two
different aspect ratios, 4 x 3 and 16 x 9, selectable via the Video Standards
menu. In 4 x 3 mode, the screen is six units high and eight units wide. In 16
x 9 mode, the screen is 18 units high and 32 units wide. The numbering
system begins in the center of the screen, and has the standard horizontal X
axis and the vertical Y axis (
Figure 31 ). For simplicity, examples in this
manual use the 4 x 3 aspect ratio.
These coordinates can be used for monitor screen locations (channel target
space with default global channel), or they can be applied to picture loca-
tions (channel source space).

Screen units are also used to define Z axis dimension depth in 3-D space.
Positive Z axis values are back behind the picture, and negative values are
in front of the picture (
Figure 32 ).
