Where is the pixel? On the screen? If you drew it, then you can index the array of pixels to get at the one you are interested in. If the pixel is part of a camera or video display shown elsewhere onscreen, then you need to access the source content -- the jpeg on disk or frame buffer content.

This is where the types I mentioned in LV come into play. If LabVIEW is a part of the video display, you will end up using the image type provided. If loading JPEGs from disk you will use the image cluster.

As for pixmaps, there are hundreds of variations in how they are defined. LV can manipulate all of them, but it may not have built-in support. With more details, I'd be happy to help.
