The problem is most likely a result of the IMAQ Create
VI not been called correctly.
When using IMAQ ExtractColorPlane
VI, you must remember that you need to call IMAQ Create
VI for every color plane that you are extracting from the image. IMAQ ExtractColorPlane
VI has an Image Source input that should be connected to the image you are extracting the planes from, but then you must also connect a different image buffer (allocated with IMAQ Create
) for each of the color planes you want like the image below.
Using IMAQ ExtractColorPlanes
Also, as discussed in the help for each of these three inputs, the image input must be an 8-bit image and the color plane is not extracted if the input is not connected.
