//	IMAGECON.H
//   
//	Created on 		09/28/95	BRH 
// Implemented on 09/28/95 BRH
//
// 09/28/95	BRH	Standard conversion functions for the standard
//						image types.  The two main standards are 8 and 24
//						bit images.  The standard converters are explained
//						in the .cpp file before each conversion function.
//
//	10/30/96	JMI	Added a message indicating this was obsoleted as it doesn't
//						seem to do anything.
//
//	11/01/96	JMI	Enhanced message referred to on 10/30/96.

// To use the dynamic linking, we will provide macros to make it easy
// for the implementer of a new type conversion to link their function.
// These macros invoke the LINKELATE macro to allocate a static CDynaLink that
// is used to link in the conversion function.

// There is a specific use of From and To in this header.  Think of it
// in terms of the preposition you use when saying, "Convert [from|to]
// extended."

// Use this to link a new Image Convertor that converts _FROM_ an extended
// format to a standard.
// Place at file scope with your image convertor function and its type enum.
// Example:
// LINK_IMAGECONV_FROM(ConvertFromBMP8, BMP8);

#define LINK_IMAGECONV_FROM(pUserFromFunc, lUserFromFuncIndex)		\
