Function photon_rs::channels::swap_channels

pub fn swap_channels(img: &mut PhotonImage, channel1: usize, channel2: usize)

Swap two channels.

Arguments

• img - A PhotonImage.
• channel1 - An index from 0 to 2, representing the Red, Green or Blue channels respectively. Red would be represented by 0, Green by 1, and Blue by 2.
• channel2 - An index from 0 to 2, representing the Red, Green or Blue channels respectively. Same as above.

Example

// For example, to swap the values of the Red channel with the values of the Blue channel:
photon::channels::swap_channels(&mut img, 0, 2);
