Function photon_rs::channels::alter_channels

pub fn alter_channels(img: &mut PhotonImage, r_amt: i16, g_amt: i16, b_amt: i16)

Increment all 3 channels’ values by adding an amt to each channel per pixel.

Arguments

• img - A PhotonImage.
• r_amt - The amount to increment/decrement the Red channel by.
• g_amt - The amount to increment/decrement the Green channel by.
• b_amt - The amount to increment/decrement the Blue channel by.

Example

// For example, to increase the values of the Red channel by 10, the Green channel by 20,
// and the Blue channel by 50:
use photon_rs::channels::alter_channels;
use photon_rs::native::open_image;

let mut img = open_image("img.jpg").expect("File should open");
alter_channels(&mut img, 10_i16, 20_i16, 50_i16);
