pub extern "C" fn __wasm_bindgen_generated_alter_blue_channel(
    arg0: <PhotonImage as RefMutFromWasmAbi>::Abi, 
    arg1: <i16 as FromWasmAbi>::Abi
) -> <() as ReturnWasmAbi>::Abi

Increment or decrement every pixel's Blue channel by a constant.

Arguments

  • img - A PhotonImage.
  • amt - The amount to increment or decrement the channel's value by for that pixel.

Example

// For example, to increase the Blue channel for all pixels by 10:
use photon::channels;
photon::channels::alter_blue_channel(&mut img, 10);
