Set red 2d array values using for loop

Question

I am trying to create a method that will get all of the red values in an image and display only the red values. I am having trouble with my getRedImage() method. I am new to thi

Answer 1

I finally figured it out:

public SimpleRGB getRedImage()
{
    SimpleRGB redImage = new SimpleRGB(width, height);

    for (int i = 0; i < width; i++)
    {
        for (int j = 0; j < height; j++)
        {
            redImage.setRed(i, j, getRed(i, j));
            redImage.setGreen(i, j, getGreen(i, j, 0);
            redImage.setBlue(i, j, getBlue(i, j, 0));
        }
    }

return redImage;
}

I had the basic structure correct but I was altering THIS red/green/blue instead of adding redImage.setRed to modify the NEW object.
