convert GIF file to the binary text file???

[minouparhizkar]

hi could anyone helping me to finish this i have no idea how to implement the program in java im trying to grabbing the pixel from image and then convert it to the txt file .i did that but it didnt give me back any result

could you tell me whats wrong with that.


here is the pixel grabber file:

package digitalpen;

import java.awt.image. *;
import java.awt.*;
// notice here that I extends an image observer, this is
// not necessary, but I need the ImageObserver to be passed as
// a paramater to get the width and height of the image

private Object m_pixels=null; // either array of ints or bytes

private ColorModel m_colorModel=nu ll;

public boolean isIndexed()
{

m_iHeight=m_ima ge.getHeight(th is);

try
{

}
catch (Exception e)
{

}

// get the palette of the image
m_colorModel=pi xelGrabber.getC olorModel();
if (!(m_colorModel instanceof IndexColorModel ))
{
// not an indexed file (ie: not a gif file)
}
else
{
m_iNumOfColors= ((IndexColorMod el)m_colorModel ).getMapSize();
}
}

// you'd need to cast the return values, which will be an array of bytes
// or an array of ints. if the file is a gif file, it will return an
// array of bytes, if jpg, you will get an array of ints
public Object getPixels()
{
return m_pixels;
}

}

public int getHeight()

}

That's too much code for me to read right now. Could you post your requirements?

I should also add that your code would almost certainly be simpler and shorter if you used newer classes like BufferedImage and left behind PixelGrabber.
