Updating color values in 3D array for picture

I have an array in Java called pic[400][400][3]

I put that array in a method that makes it into an image.

Before I call the method to make the array into a picture, I want to change the color values for each pixel. I am struggling with the concept of how to select the value I want to alter and then what I need to enter to adjust the color values in the array. Any help is appreciated.

Solution

  • pic[xcoord][ycoord][0] would be red.

    pic[xcoord][ycoord][1] would be blue.

    pic[xcoord][ycoord][2] would be green.

    This would be easier, however, with a BufferedImage. There is getRGB(), setRGB(), and it supports alpha values. It is also a lot easier to save and load images.
