A display node in a graphical program may be used to automatically
transfer an image from an embedded device lacking display capabilities to
another device having a display. A method for displaying an image
involves creating a graphical program on a display in response to user
input and executing the graphical program on a first embedded system. The
graphical program may include a first node for acquiring an image and a
second node for displaying the image. If the first embedded system is
coupled to a second system having a display device, executing the
graphical program involves the second node transferring the image to the
second system and directing the second system to display the image on the
display device of the second system. If the first embedded system is not
coupled to a second system having a display device, the second node may
perform no display operation during execution.
