Constructor Detail

A_CircularInstrument

public A_CircularInstrument(java.lang.String id,
                            int canvasSize,
                            CoordinateCartesianAbsolute canvasAnchor)

Parameters:

id - - the unique instrument identifier

canvasSize - - the square size of the instrument footprint in pixels

canvasAnchor - - the anchor position for the center of the canvas in pixels

Method Detail

mapAngle

protected AngleMathematical mapAngle(CircularFaceplateDescriptor<_UNIT_> faceplate,
                                     _UNIT_ value)

Maps a unit value to an angle on the faceplate arc.

Parameters:
