Changing image aspect ratio (Aspect)
In the source coordinate space, this changes the aspect
ratio in the X-axis direction and Y-axis direction, either
independently or simultaneously.
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.

You can display the following kinds of graphics.
Wire frames
A wire frame displays an image enclosed in a frames, so
Changing image perspective (Perspective)
In the target coordinate space, this changes the perspective
on the image by changing an imaginary viewpoint, without
changing the position of the image.
The X-axis and Y-axis values define the position of the
viewpoint. The Z-axis value defines its distance from the
image.
that you can check the position and size of the image. If
there is a shadow, a frame is shown for the shadow as well.
Coordinate axes
This is a three-dimensional display of coordinates in local
or global coordinate space.
You can check the origin of the axes and the directions of
the X-, Y-, and Z-axes.

Channel ID
This displays the channel number so that you can check
which channel you are using. This is a useful feature when
you are working with multiple channels.
Channel IDs are displayed differently in local and global
coordinate space.
•
In local coordinate space, the channel number is
displayed along with “F” or “B” to indicate whether you

are looking at the front (F) or back (B) of the current wire
frame. For example, “1F” means the front of the wire
frame on channel 1 in local coordinate space.
•
In global coordinate space, the channel number is
displayed along with “G” to indicate global. For
example, “G2” means channel 2 in global coordinate
space.
