Many image acquisition applications require that one or more images 
be displayed. You have several options for displaying images in LabVIEW.

You can display an image directly on the front panel using an Image 
Display control, which is available on the Vision Controls palette. To 
display an image on an Image Display control, place the control on the front 
panel of your VI. On the block diagram, wire Image Out from an 
acquisition VI to the Image Display control terminal. 

Figure 4-6 illustrates using an image control to display an image using an 
Image Display control. For more information about Image Display 
controls, refer to the NI Vision for LabVIEW VI Reference Help.

If you have NI Vision for LabVIEW, you can display an image in an 
external window using IMAQ WindDraw, located at Vision and Motion»
Vision Utilities»External Display. Use IMAQ WindDraw when you need 
more image size and location control.

Figure 4-7 illustrates using IMAQ WindDraw to display an image acquired 
using IMAQdx Snap. You can display images in the same way using any 
acquisition type. For more information about the display capabilities of 
NI Vision, refer to the NI Vision for LabVIEW User Manual.
