iflColormap(3)

NAME
     iflColormap - class for defining colormaps

INHERITS FROM
     iflLut

HEADER FILE
     #include <ifl/iflColormap.h>

CLASS DESCRIPTION
     iflColormap is derived from iflLut. The only difference is the removal of
     the ability to have the table length not be a one-to-one mapping onto the
     domain of the lut.  It is intended to represent the colormap for image
     files that have an iflRGBPalette color model.  Refer to the iflLut man
     page for more info on the supported access methods.

CLASS MEMBER FUNCTION SUMMARY
     Constructors

          iflColormap()
          iflColormap(int numChan, iflDataType dtype, double min, double max)
          iflColormap(void* table, int numChan, iflDataType dtype,
                      double min, double max)


FUNCTION DESCRIPTIONS
     iflColormap()

          iflColormap(int numChan, iflDataType dtype, double min, double max)
          iflColormap(void* table, int numChan, iflDataType dtype,
                      double min, double max)
          iflColormap()


          Constructors for the iflColormap class.  The number of tables or
          channels in the colormap is specified by numChan and the colormap
          data type is specified by dtype.  The domain of values the table
          handles is from min to max.  The length of each table is either
          max-min+1.  The second constructor creates an iflColormap whose
          look-up table data is pointed to by table. The final constructor
          generates an empty iflColormap.  This can be useful in conjuction
          with the assigment operator.
