Function photon_rs::channels::__wasm_bindgen_generated_alter_two_channels

pub extern "C" fn __wasm_bindgen_generated_alter_two_channels(
    arg0: <PhotonImage as RefMutFromWasmAbi>::Abi,
    arg1: <usize as FromWasmAbi>::Abi,
    arg2: <i16 as FromWasmAbi>::Abi,
    arg3: <usize as FromWasmAbi>::Abi,
    arg4: <i16 as FromWasmAbi>::Abi
) -> <() as ReturnWasmAbi>::Abi

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:
use photon_rs::channels::alter_two_channels;
use photon_rs::native::open_image;

let mut img = open_image("img.jpg").expect("File should open");
alter_two_channels(&mut img, 0_usize, 10_i16, 2_usize, 20_i16);
