#define PCOLOUR_CONVERTER ( cls,
src,
dst   )     PCOLOUR_CONVERTER2(cls,PColourConverter,src,dst)

Declare a colour converter class with Convert() function. This should only be used once and at the global scope level for each converter. It declares everything needs so only the body of the Convert() function need be added.

#define PCOLOUR_CONVERTER2 ( cls,
ancestor,
src,
dst   ) 

Value:

class cls : public ancestor { \
  public: \
  cls(const PString & srcFmt, const PString & dstFmt, unsigned w, unsigned h) \
    : ancestor(srcFmt, dstFmt, w, h) { } \
  virtual BOOL Convert(const BYTE *, BYTE *, PINDEX * = NULL); \
  virtual BOOL Convert(const BYTE *, BYTE *, unsigned int , PINDEX * = NULL); \
}; \
