Detailed Description

Blended pixel value calculation for two overlaped rasters.

Definition in file Blender.cpp.

Macro Definition Documentation

#define getPerpendicularDistance	(		pX,
			pY,
			lineAX,
			lineAY,
			lineBX,
			lineBY,
			aux1,
			aux2,
			perpDist
	)

Value:

aux1 = lineAX - lineBX; \
  aux2 = lineAY - lineBY; \
  if( aux1 == 0.0 ) \
  { \
    perpDist = std::abs( pX - lineAX ); \
  } \
  else if( aux2 == 0.0 ) \
  { \
    perpDist = std::abs( pY - lineAY ); \
  } \
  else \
  { \
    perpDist = \
      std::abs( \
        ( aux2 * pX ) - ( aux1 * pY ) + ( lineAX * lineBY ) - ( lineBX * lineAY ) \
      ) \
      / \
      std::sqrt( ( aux1 * aux1 ) + ( aux2 * aux2 ) ); \
