Method Detail

getTimeOffsetMillis

public long getTimeOffsetMillis()

Returns:

the timeOffsetMillis

setScales

public void setScales(double xScale,
             double yScale,
             int specWidth,
             int specHeight)

Parameters:

xScale - pixels per millisecond

yScale - 2/fftLength

specWidth - display width

specHeight - display height

setOffset

public void setOffset(long timeOffsetMillis,
             int timeOffsetPixs)

Set the x and the time offset

Parameters:

timeOffsetMillis - time offset in Java milliseconds

timeOffsetPixs - position in pixels

getCoord3d

public Coordinate3d getCoord3d(double d1,
                      double d2,
                      double d3)

Description copied from class: GeneralProjector

Function ultimately used by a PamDataBlock to convert it's own data, in whatever form that is in into screen coordinates.

Specified by:

getCoord3d in class GeneralProjector

Parameters:

d1 - d2 and d3 are data representing whatever is appropriate for the concrete instance of the projector (e.g. Latitude, Longitude, depth, Time Frequency, etc)

Returns:

A 3 dimensional coordinate (realistically z is never currently used)

dataToX

public double dataToX(double d1,
             double d2)

dataToY

public double dataToY(double d1,
             double frequency)

getSpectrogramDisplay

public SpectrogramDisplay getSpectrogramDisplay()

Returns:

the spectrogramDisplay

setChannel

public void setChannel(int channel)

Parameters:

channel - the channel to set

getChannel

public int getChannel()

Returns:

the channel
