Thread: Replacing red with a picture

For this assignment I have a picture of myself with a green screen background. I have to take this picture of myself and replace the green screen background with another picture (IE: a beach is what I used)
In my picture I am given a red robe to wear. After changing the background I have to replace all the red on the robe with another picture.
I have code that does exactly what I need by replacing the greenscreen background but I do not know how to go about changing the red. This is the code I have so far:

  public void chromakey( Picture greenScreen )
  {
    Pixel personsPix;
    Pixel backgroundPix;
 
    int x;
    x = 0;
    while( x < this.getWidth() )
    {
      int y;
      y = 0;
      while( y < this.getHeight())
      {
        personsPix = this.getPixel(x, y); if(personsPix.getGreen() > (personsPix.getBlue() + personsPix.getRed()))
        {
          backgroundPix = greenScreen.getPixel (x, y);
          personsPix.setColor(backgroundPix.getColor());
        }
        y = y + 1;
      }
      x = x + 1;
    }
  }
 
  public static void main(String[] args) 
  {
     FileChooser.pickMediaPath();
     String fileName = FileChooser.pickAFile();
     Picture personPicture = new Picture(fileName);
     Picture backgroundPicture = new Picture(FileChooser.pickAFile() );
     personPicture.chromakey(backgroundPicture);
     personPicture.explore();
  }

Example code was given that shows how to remove red eye from a picture:

public void removeRedEye(int startX, int startY, int endX, int endY, Color newColor)
{
Pixel pixel = null;
for(int x = startX; x < endX; x++)
{
for (int y = startY; y < endY; y++)
{
pixel = getPixel(x,y);
if(pixel.colorDistance(Color.red) < 167)
pixel.setColor(newColor)
}
}
}

Since instead of replacing the red with another color I have to replace it with another picture, the parameter Color newColor means nothing to me. I had an idea to change that parameter to Picture newPicture
but then that makes a lot of the sample code void and I do not know how to go about changing it.

I tried PMing with the assignement pdf for easier to read directions on what needs to happen. Sorry if it was confusing

Nevermind then, thanks anyway
