how to get individual red, green, blue pixel values from image? about image HOT 3 CLOSED

After calling grayscale there are no longer red / green / blue pixel values, there's only a single "luma" value that ranges from black (0) to white (255 or 65535 depending on the bit-depth).

Specifically, the type of pixel within your loop is Luma<u16> so based on that documentation page, you can get contents by doing pixel.0[0]. If you hadn't converted to grayscale, you would be working with an RGB image and your pixel would have type Rgb<u16> and you could do:

for pixel in my_rgb_image.pixels() {
    let red = pixel.0[0];
    let green = pixel.0[1];
    let blue = pixel.0[2];
}

As a side note, most images are 8-bits per channel, so calling to_rgb8 would work just as well as to_rgb16

This is my function to actually do the image manipulation.
