Implementations§

Source§

impl Scaler

Source

pub fn new( src_width: NonZeroU16, src_height: NonZeroU16, pix_fmt: PixelFormat, dst_width: NonZeroU16, dst_height: NonZeroU16, ) -> Result<Self, CreateScalerError>

Source

pub fn scale( &mut self, src_frame: &Frame, dst_frame: &mut Frame, ) -> Result<(), ScalerError>

Scales src_frame to another size and stores it in dst_frame.

Will check that src_frame matches scaler configuration. dst_frame will be resized if necessary.
