Location Size
Changes the size of the whole image.
• Because shrinking and magnification of the image in the source coordinate
space is done in three-dimensional space, magnifying the image emphasizes
the sense of perspective.
• 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.
