Chapter 11 DME Operations
• Because shrinking and magnification of the image in the
target coordinate space is a conversion of the two-
dimensional image displayed on the monitor, shrinking
and magnification does not change the shape of the
image.

coordinate space
Magnification and shrinking in the target
coordinate space
Aspect
In the source coordinate space, changes the aspect ratio in
the x-axis direction and y-axis direction, either
independently or simultaneously.
Perspective
In the target coordinate space, changes the perspective on
the image by changing an imaginary view point, without
changing the position of the image.
The x-axis and y-axis values define the position of the
view point. The z-axis value defines its distance from the
image.
Skew
In the source coordinate space, change the skew of the
image on the x-axis or y-axis.
Graphics Display
Graphics display is a function that allows you to display
wire frames, coordinate axes and a grid over the current
DME image, to make it easier to create effects in three-
dimensional coordinate space.
Graphics displayed by this function can also be output to
the monitor output connector.
To make graphics display settings, use the DME menu.
(For details, see “Graphics Display Operation” (page
238).)
You can display the following kinds of graphics.
Wire frames
A wire frame displays an image enclosed in a frames, so
that you can check the position and size of the image. If
there is a shadow (see page 306), a frame is shown for the
shadow as well.
