Solve It
In this example we want to change only the background of the Duke logo. We will turn the background green and leave the rest of the logo unchanged. Since only the background pixels have a blue value of 255, we can use this condition in an if statement to identify the pixels that should change to green.
Code It
// blue devil on a green background
var image = new SimpleImage("duke_blue_devil.png");
for (var pixel of image.values()) {
if (pixel.getBlue() == 255) {
pixel.setRed(0);
pixel.setGreen(255);
pixel.setBlue(100);
}
}
print(image);
