Package Spectrogram

Class DirectDrawProjector

java.lang.Object

PamView.GeneralProjector<Coordinate3d>

Spectrogram.DirectDrawProjector

public class DirectDrawProjector
extends GeneralProjector<Coordinate3d>

Spectrgoram projector for drawing directly onto the spectrogram display.

Unlike the SpectroramProjector, which maps pixels 1:1, this projector needs the scales of the display since it draws directly onto the AWT component.

Method Summary

Modifier and Type	Method	Description
Coordinate3d	getCoord3d(double timeMillis, double freqHz, double d3)	Function ultimately used by a PamDataBlock to convert it's own data, in whatever form that is in into screen coordinates.
Coordinate3d	getCoord3d(Coordinate3d dataValues)	Same as getCoordinate3d but using the generic type
Coordinate3d	getDataPosition(PamCoordinate screenPosition)	Do the exact opposite of getCoord3d and turn a screen position back into a data coordinate (e.g.
int	getDisplayHeight()
int	getDisplayWidth()
int	getPanelId()
SpectrogramDisplay	getSpectrogramDisplay()

Method Details

getCoord3d

public Coordinate3d getCoord3d(Coordinate3d dataValues)

Description copied from class: GeneralProjector

Same as getCoordinate3d but using the generic type

Specified by:

getCoord3d in class GeneralProjector<Coordinate3d>

Parameters:

dataValues - object extending PamCoordinate

Returns:

3d coordinate.

getCoord3d

public Coordinate3d getCoord3d(double timeMillis,
 double freqHz,
 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<Coordinate3d>

Parameters:

timeMillis - 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)

getDataPosition

public Coordinate3d getDataPosition(PamCoordinate screenPosition)

Description copied from class: GeneralProjector

Do the exact opposite of getCoord3d and turn a screen position back into a data coordinate (e.g. a time / freq, a lat long, etc)/.

Specified by:

getDataPosition in class GeneralProjector<Coordinate3d>

Parameters:

screenPosition - screen position

Returns:

data object.

getSpectrogramDisplay

public SpectrogramDisplay getSpectrogramDisplay()

Returns:

the spectrogramDisplay

getDisplayHeight

public int getDisplayHeight()

Returns:

the displayHeight

getDisplayWidth

public int getDisplayWidth()

Returns:

the displayWidth

getPanelId

public int getPanelId()

Returns:

the panelId
