Hello Michael,
You can open an image file (bmp or jpg) with IMAQ ReadFile (located in the IMAQ Vision toolkit). If the image is in color, then you will need to select RGB or HSL for the Image Type (otherwise you will likely be using 8 bit for a greyscale image - default).
- I attached a sample program to open an image (you will need to select the correct data type) and display it using the IMAQ WindDraw (also included with IMAQ Vision). The VI was written and saved in LabVIEW 6i and IMAQ Vision 6.0.
With IMAQ Vision, you will also be able to convert the RGB image into HSL and/or extract the image into color planes (R, G & B or H, S & L) using IMAQ ExtractColorPlanes.
