All Implemented Interfaces:

Serializable, BeadFeatureRenderer, FeatureRenderer, Changeable

public class EllipticalBeadRenderer
extends AbstractBeadRenderer

EllipticalBeadRenderer renders features as simple ellipses. Their outline and fill Paint, Stroke, feature depth, Y-axis displacement are configurable. Also configurable is the minimum ratio of long axis to short axis of the ellipse - this prevents long features also becoming ever wider and obscuring neighbours.

Method Detail

renderBead

public void renderBead(Graphics2D g2,
                       Feature f,
                       SequenceRenderContext context)

renderBead renders features as simple ellipse.

Specified by:

renderBead in interface BeadFeatureRenderer

Specified by:

renderBead in class AbstractBeadRenderer

Parameters:

g2 - a Graphics2D context.

f - a Feature to render.

context - a SequenceRenderContext context.

getDepth

public double getDepth(SequenceRenderContext context)

getDepth calculates the depth required by this renderer to display its beads.

Specified by:

getDepth in interface FeatureRenderer

Overrides:

getDepth in class AbstractBeadRenderer

Parameters:

context - a SequenceRenderContext object.

Returns:

a double.

getDimensionRatio

public double getDimensionRatio()

getDimensionRatio returns the maximum ratio of long dimension to short dimension of the bead. This should be equal, or greater than 1.

Returns:

a double.

setDimensionRatio

public void setDimensionRatio(double ratio)
                       throws ChangeVetoException

setDimensionRatio sets the minimum ratio of long dimension to short dimension of the bead. This should be equal, or greater than 1.

Parameters:

ratio - a double ratio of depth.

Throws:

ChangeVetoException - if an error occurs.
