Thanks Neville, I think this should help, strange thing is that the IMAQ Vision for LabVIEW VI reference Help concerning "simple calibration" seems to be wrong, it suggests different inputs then are really there in the VI. I should report this error to NI. René QUOTE(Neville D @ Aug 29 2007, 06:56 PM)

Hi folks , I am new to this forum, but an oldie as LabVIEW programming is concerned. Yet I can't seem to find an easy way to tell IMAQ Vision to use real_world coordinates and sizes. For example if I use the particle analysis I get can particle coordinates and sizes, but they are in pixel-units. I would like to get um's or um2's , is there an easy way to tell IMAQ that it should convert pixels to um's (with my own scaling e.g. 1 pixel = 5 um's), There is an image-calibration option that seem to do such a thing but that is far to complicated. If it matters: I use LabVIEW 7.1 and IMAQ Vision 7.1.1 on an windows XP system . Any help is appreciated, René
