FLAMLEVS: Proc to set RGBLEVS to a red flame color scheme
LEVS $ Contour levels
RGBGAMMA $ 0.0 Gamma correction parameter
RGBLEVS @ 0.0 1.0 RGB for each LEVS in order
Proc: This procedure will set RGBGAMMA if it is not positive, will
examine the LEVS values and set them to -10 to -1 followed by 1
to 10 if they are not set. Then it will determine a red flame
pattern of colors from dark red through yellow and orange to
white. It will set RGBLEVS so that the first positive LEVS and
first negative LEVS will be depp red, the 2nd positive and
2nd negative LEVS will be somewhat brighter red and so forth
to the highest LEVS (positive and or negative) which will be
Before using this procedure you must enter
which will define this and 3 other procedures. Any time you
change the values in LEVS, you should then enter
again to select the new set of colors. Note that these colors
are similar to those of the verb TVPHLAME.
RGBGAMMA...If 0 on input, set to 2.2. The gamma correction
parameter to adjust colors (value used = input value to
the 1/RGBGAMMA power). Larger values make more pastel
LEVS.......Contour level multipliers. Up to 30 values in increasing
order - if all 0 on input, set to -10 to -1, 1, to 10.
Defines which values require colors and what their range
should be. Thus, if you change LEVS, you should execute
RGBLEVS....RGB colors (3,30) for each of the LEVS in use.
II, JJ, KK, XX, YY, RR, GG, BB, TT are all changed by the procedure.
