For Loops: Changing Colors
----------------------------
img = new SimpleImage("x.png");
img.setZoom(20);
for (pixel : img) {
    pixel.setRed(255);
}
print(img);

For Loops: Relative Colors
--------------------------
img = new SimpleImage("flowers.jpg");
img.setZoom(0.5);
for (pixel : img) {
    pixel.setRed(pixel.getRed() * 1.5);
}
print(img);


A Puzzle
---------
img = new SimpleImage("51020-banana.png");
img.setZoom(0.5);
for (pixel : img) {
    pixel.setRed(pixel.getRed() * 20);
    pixel.setGreen(pixel.getGreen() * 5);
    pixel.setBlue(pixel.getBlue() * 10);
}
print(img);


Another Mystery
-----------------

image = new SimpleImage("puzzle-gold.png");
image.setZoom(0.5);
for (pixel: image) {
    pixel.setRed(pixel.getRed() * 10);
    pixel.setGreen(0);
    pixel.setBlue(0);
}

print(image);


Grayscale
----------
img = new SimpleImage("flowers.jpg");
img.setZoom(0.5);

for (pixel : img) {
    avg = (pixel.getRed() + pixel.getGreen() + pixel.getBlue()) / 3;
    pixel.setRGB(avg, avg, avg);
}
print(img);

Blur Filter Code
----------------

img = new SimpleImage("poppy.jpg");
result = new SimpleImage("poppy-blur.jpg");
result.setAsBig(img);
result.setZoom(0.5);

for (pixel : img) {
    redSum = 0;
    greenSum = 0;
    blueSum = 0;
    for (neighbor : img.getNeighbors(pixel)) {
       redSum = neighbor.getRed() + redSum;
       greenSum = neighbor.getGreen() + greenSum;
       blueSum = neighbor.getBlue() + blueSum;
    }
    redAvg = redSum / img.countNeighbors(pixel);
    greenAvg = greenSum / img.countNeighbors(pixel);
    blueAvg = blueSum / img.countNeighbors(pixel);
    
    newPixel = result.getPixel(pixel.getX(), pixel.getY());
    newPixel.setRGB(redAvg, greenAvg, blueAvg);
}

print(result);
