Method Detail

setLocation

public void setLocation(java.awt.geom.GeneralPath gp)
Description copied from interface: OMLabeler
The OMLabeler should be able to determine its pixel location based on the GeneralPath of the OMGraphic. This will generally cause the label to be placed in the center of the bounds of the shape.

Specified by:
setLocation in interface OMLabeler
Parameters:
gp -

setLocation

public void setLocation(java.awt.Point p)
Description copied from interface: OMLabeler
The OMLabeler should be able to set its pixel location directly.

Specified by:
setLocation in interface OMLabeler
Parameters:
p -

setLocation

public void setLocation(int[] xpoints,
                        int[] ypoints)
Description copied from interface: OMLabeler
The OMLabeler should be able to determine its pixel location based on a set of x and y pixel coordinates common in OMGraphics.

Specified by:
setLocation in interface OMLabeler
Parameters:
xpoints -
ypoints -
