Figure 24. Aspect, Skew, Perspective
Aspect
Scaling the X or Y components of the picture. X axis changes affect hori-
zontal size, Y axis changes affect vertical size (
Figure 24 ). Z axis changes
affect both X and Y dimensions, and is the same as Size.
Skew
Slanting the picture in the X (horizontal) and Y (vertical) directions
(
Figure 24 ).
Perspective
Changing the viewer’s apparent viewpoint of a picture. This only applies
when a picture is tilted so part of it is farther from the viewer.
The farther portion appears smaller than the closer portion, and the
amount of perspective controls how much smaller the distant part is
(
Figure 24 on page 59 ). Multi-channel perspective is discussed later in this
section.
