[−][src]Function photon_rs::channels::alter_two_channels
pub fn alter_two_channels(
img: &mut PhotonImage,
channel1: usize,
amt1: i16,
channel2: usize,
amt2: i16
)
Increment/decrement two channels' values simultaneously by adding an amt to each channel per pixel.
Arguments
img
- A PhotonImage.channel1
- A usize from 0 to 2 that represents either the R, G or B channels.amt1
- The amount to increment/decrement the channel's value by for that pixel.channel2
-A usize from 0 to 2 that represents either the R, G or B channels.amt2
- The amount to increment/decrement the channel's value by for that pixel.
Example
// For example, to increase the values of the Red and Blue channels per pixel: photon::channels::inc_two_channels(&mut img, 0, 10, 2, 20);
