public class JMFLivePushPixelSource

extends PixelSource

implements javax.media.ControllerListener

Constructor Summary

JMFLivePushPixelSource(javax.swing.JFrame _f, int pw, int ph)

Method Summary

java.lang.String	changeSource(int whichSource)
void	controllerUpdate(javax.media.ControllerEvent event)
java.awt.image.BufferedImage	getImage() Gives you a bufferedImage from the live camera.
int[]	getPixel(int x, int y) This returns a 3 element array which contains the values for Red Green and Blue at the specified x,y coordinate.
void	getPixelArray(int[] _newPixels) This tickles tickles the video and puts the pixels in an int array that you supplied .
boolean	grabFrame() This gives you a fresh frame for getPixel and setPixel to operate on.
void	idleIt() This tickles whatever is suppling the video to give up fresh pixels.
void	idleIt(int numberOfTimes) This tickles whatever is suppling the video, with DV cameras you may have to tickle them many times between every frames to get rid of a lag.
void	killSession() Be sure to call this when you close or destroy your main window so a connection to your camera is not left hanging .
void	videoSettings() Gives you a pop up dialog box for the video digitizer driver.

Constructor Detail

JMFLivePushPixelSource

public JMFLivePushPixelSource(javax.swing.JFrame _f,
                              int pw,
                              int ph)

Method Detail

idleIt

public void idleIt()

This tickles whatever is suppling the video to give up fresh pixels.

Overrides:

idleIt in class PixelSource

idleIt

public void idleIt(int numberOfTimes)

This tickles whatever is suppling the video, with DV cameras you may have to tickle them many times between every frames to get rid of a lag.

getImage

public java.awt.image.BufferedImage getImage()

Gives you a bufferedImage from the live camera.

Overrides:

getImage in class PixelSource

getPixelArray

public void getPixelArray(int[] _newPixels)

This tickles tickles the video and puts the pixels in an int array that you supplied .

Overrides:

getPixelArray in class PixelSource

Parameters:

_newPixels - array that you want the pixel values placed into

grabFrame

public boolean grabFrame()

This gives you a fresh frame for getPixel and setPixel to operate on.

Overrides:

grabFrame in class PixelSource

Returns:

killSession

public void killSession()

Be sure to call this when you close or destroy your main window so a connection to your camera is not left hanging .

Overrides:

killSession in class PixelSource

getPixel

public int[] getPixel(int x,
                      int y)

This returns a 3 element array which contains the values for Red Green and Blue at the specified x,y coordinate. A fourth number is returned which is the offset in the big array for this pixel in case you want to manipulate it directly. This is very convenient but maybe a tiny bit slower. If you want speed you sould use getPixelArray and pull out the Red Green and Blue in your own object using shifting and Masking

Overrides:

getPixel in class PixelSource

Parameters:

x -

y -

Returns:

integer array with the offset in 0, the r in 1, the g in 2 and the b in 3

controllerUpdate

public void controllerUpdate(javax.media.ControllerEvent event)

Specified by:

controllerUpdate in interface javax.media.ControllerListener

changeSource

public java.lang.String changeSource(int whichSource)

videoSettings

public void videoSettings()

Description copied from class: PixelSource

Gives you a pop up dialog box for the video digitizer driver.

Overrides:

videoSettings in class PixelSource
