Yourintensity graph now should appear similar to the image shown in
Figure 4-9. Form ore information on the Intensity Graph, consult your
LabVIEW documentation
Figure4-9. IntensityGraph for Image Display
Usethe IMAQ ImageToArray VI to copy an image from an image buffer
intoa LabVIEW array. Then you can wire this array directly to an Intensity
Graph for display.Figure 4-10 illustrates using an Intensity Graph to
display an image acquired using IMAQ1394Snap.
Figure4-10. Displayingan Image Using an Intensity Graph
Todisplay an RGB image on a picture control, place the picture control on
thefront panel of your VI. Use the IMAQColorImageToArray VI to copy
an imagefrom animage buffer into a LabVIEW array.Then you can wire
thisarraytotheDrawTrue-Color Pixmap VI. Wire the new image output
fromDraw True-Color Pixmap to the picture control indicator. For more
informationon the picture control, consult the LabV IEW online reference.
Figure 4-11 illustrates using a picture control to display an RGB image
acquired with the IMAQ1394Snap VI.
