    Hi! Anyone knows how to create a colorbar without using an RGB color table (i.e. with your self-created color array)? Thnx, Wouter

    Hi, what do you mean by "without using an RGB color table" : - a pre-defined color table ? a "self-created color array" should be define in RGB :s maybe you can add you color table to the IDL color table using the "MODIFYCT" procedure, and after you call it when defining the colorbar. Vincent

    You can use a 3x256 array for the RGB_TABLE. ARR = BYTARR(3,256) ARR(0,*) = R ARR(1,*) = G ARR(2,*) = B i = IMAGE(img, rgb_table = arr)
