Form XObjects
In
“Transformations” on page 62
, we used the
q
and
Q
operators to display a single
object using various transformations. However, we had to recite the operations for
drawing the object each time. A
Form XObject
allows us to store a set of graphics
instructions, and use them repeatedly (even on different pages), at differing scales and
positions.
Form XObjects have nothing to do with PDF forms (the kind you fill in).
