Figure 13: [
ISOCONT, iso_struct_raster, iso_struct_raster, NLEVELS=10 ]
Display a color image of iso_struct_raster, with 10 contour levels of
iso_struct_raster. These contour values are uniformly spaced in the
[MIN_VALUE,MAX_VALUE] interval. It is possible to specify directly the
minimum and maximum values by setting respectively the MIN_VALUE and
MAX_VALUE. It is also possible to directly specify the contour values by
setting the keyword array LEVELS=[value_1,value_2,...].
