Image axis movement
Scale image (Location Size)
Changes the size of the whole image.
Because shrinking and magnification of the image in
source space is done in three-dimensional space,
magnifying the image enhances perspective.
Because shrinking and magnification of the image in target
space is a conversion to a two-dimensional image
displayed on the monitor, shrinking and magnification
does not change the shape of the image.
Scaling in source space
Scaling in target space
Change image aspect ratio (Aspect)
In source space, changes the aspect ratio in the X-axis
direction and Y-axis direction, either independently or
simultaneously.
Change image perspective (Perspective)
In target space, changes the perspective of the image by
changing the virtual viewpoint, without changing the
position of the image.
The X-axis and Y-axis values define the position of the
view point, and the Z-axis value defines its distance from
the image.
Change image slope (Skew)
In source space, changes the slope of the image on the X-
axis or Y-axis.
