All Implemented Interfaces:

de.unihalle.informatik.Alida.datatypes.ALDConfigurationValidator, de.unihalle.informatik.Alida.operator.events.ALDOperatorExecutionProgressEventListener, EventListener

@ALDAOperator(genericExecutionMode=ALL,
              level=APPLICATION)
public class DrawEllipse
extends MTBOperator

Operator to draw an ellipse to a given image.

Note that this is a really brute-force implementation. Ellipses are sampled only with 360 steps and no Bresenham algorithm or something similar is applied. Also there are no special efforts to make the drawing process efficient.

Enable/disable copy of input image.

Parameters:

f - If true (default), input image is copied.

setZTCCoordinates

public void setZTCCoordinates(int z,
                              int t,
                              int c)

Parameters:

z - z-slice coordinate.

t - t-slice coordinate.

c - c-slice coordinate.

getResultImage

public MTBImage getResultImage()

Get result image.

Returns:

Image with drawn ellipse.

operate

public void operate()

Specified by:

operate in class de.unihalle.informatik.Alida.operator.ALDOperator

drawEllipse

private void drawEllipse()
