Constructor Detail

OffsetOriginStep.Position

public OffsetOriginStep.Position(double x,
                                 double y)

Constructs a position with specified image coordinates, and transforms those coordinates to set the world coordinates.

Parameters:

x - the image x coordinate

y - the image y coordinate

Method Detail

setXY

public void setXY(double x,
                  double y)

Overrides TPoint setXY method. This moves the origin so the world coordinates do not change.

Specified by:

setXY in interface Interactive

Overrides:

setXY in class TPoint

Parameters:

x - the x position

y - the y position

setAdjusting

public void setAdjusting(boolean adjusting)

Overrides TPoint method.

Overrides:

setAdjusting in class TPoint

Parameters:

adjusting - true if being dragged

showCoordinates

public void showCoordinates(VideoPanel vidPanel)

Overrides TPoint showCoordinates method. This updates the values of the x and y fields.

Overrides:

showCoordinates in class TPoint

Parameters:

vidPanel - the video panel
