Required Methods§

Source

fn set_threading_policy(&mut self, threading_policy: ThreadingPolicy)

Source

fn resize_rgb<'a>( &'a self, new_size: ImageSize, store: ImageStore<'a, u8, 3>, ) -> Result<ImageStore<'a, u8, 3>, PicScaleError>

Performs rescaling for RGB, channel order does not matter

Source

fn resize_rgba<'a>( &'a self, new_size: ImageSize, store: ImageStore<'a, u8, 4>, premultiply_alpha: bool, ) -> Result<ImageStore<'a, u8, 4>, PicScaleError>

Performs rescaling for RGBA, for pre-multiplying alpha, converting to LUV or LAB alpha must be last channel
