     iflColormap - class for defining colormaps

INHERITS FROM    [Toc]    [Back]

HEADER FILE    [Toc]    [Back]

     #include <ifl/iflColormap.h>

CLASS DESCRIPTION    [Toc]    [Back]

     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    [Toc]    [Back]

     Constructors

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

FUNCTION DESCRIPTIONS    [Toc]    [Back]

     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.
