This is the program:
set_plot,'ps'
device,filename='f:\image.ps',bits=8,/color

data = Dist(300)
step = (Max(data) - Min(data)) / 16.
levels = Indgen(16) * step + Min(data)
;Device, Decomposed=1
CTLoad, 14, /Brewer
pos = [0.15, 0.15, 0.9, 0.75]
;Erase, Color=FSC_Color('ivory')
TVImage, BytScl(data), POSITION=pos
Contour, data, /NOERASE, POSITION=pos, XSTYLE=1, YSTYLE=1, $
LEVELS=levels, COLOR=FSC_Color('black'), $
C_LABEL=Replicate(1, 16)
Colorbar, NCOLORS=256, RANGE=[Min(data), Max(data)], DIVISIONS=4,
$
POSITION=[0.15, 0.8, 0.9, 0.85], /TOP, COLOR=FSC_Color
('black')

device,/close
end

The result is there is a black line between 106 to 159 on the
colorbar. I donot know why.
