Color value of a cell


    Jan 20 2006 | 4:34 pm
    I am trying to collect the value of a specific cell in a jit.matrix. when i use the "getcell" attribute it gives me the values of all four channels (argb)... all i want is one value between 1 and 256. is there a simple way to output this value to a number box?

      Hello, If by "one value" you mean the luminance of the cell, you will need to pass through jit.rgb2luma, to convert your matrix into a 1 plane. Otherwise, you could always just choose an arbitrary plane to track.
