Function photon_rs::monochrome::monochrome

pub fn monochrome(
    img: &mut PhotonImage,
    r_offset: u32,
    g_offset: u32,
    b_offset: u32
)

Apply a monochrome effect of a certain colour.

It does so by averaging the R, G, and B values of a pixel, and then adding a separate value to that averaged value for each channel to produce a tint.

Arguments

• photon_image - A PhotonImage.
• r_offset - The value to add to the Red channel per pixel.
• g_offset - The value to add to the Green channel per pixel.
• b_offset - The value to add to the Blue channel per pixel.

Example

// For example, to apply a monochrome effect to an image:
use photon_rs::monochrome::monochrome;
use photon_rs::native::open_image;

let mut img = open_image("img.jpg").expect("File should open");
monochrome(&mut img, 40_u32, 50_u32, 100_u32);
