Member Function Documentation

void OrientedLineSegment::Blend (  const OrientedLineSegment &  segment1, const OrientedLineSegment &  segment2, const float &  blendWeight, OrientedLineSegment &  outSegment )  [static]

This static method blends between two sets line segments, using the value of blendWeight to specify the the ratio of the blend, and writes out the blended line segment into outSegment.

float OrientedLineSegment::distance (  const int &  x, const int &  y )  const

This method returns the (signed) distance of a point from the line segment/

void OrientedLineSegment::getPerpendicular (  float &  x, float &  y )  const

This method sets the values (x,y) to the coordinates of the unit-vector perpendicular to the direction of the line segment.

void OrientedLineSegment::GetSourcePosition (  const OrientedLineSegment &  source, const OrientedLineSegment &  destination, const int &  destinationX, const int &  destinationY, float &  sourceX, float &  sourceY )  [static]

This static method sets the value of the source pixel position (sourceX,sourceY), given the destination pixel position and a pair of corresponding source and destination line segments/

float OrientedLineSegment::getWeight (  const int &  x, const int &  y )  const

Given a point at position (x,y), this method returns the weight of the line segment's contribution to the point.

float OrientedLineSegment::length (  void   )  const

This method returns the length of the line segment.

int OrientedLineSegment::read (  FILE *  fp  )

This method reads in a line segment from a file.
