Required Associated Types

type D: 'static + Copy

Pixel data type (e.g. u8 or f32)

type C: ChanTrait

Number of channels (e.g. Chan1)

Required Methods

fn image_slice(&self) -> &[Self::D]

Get the raw data for the entire image, including padding.

fn raw_ptr(&self) -> *const Self::D

fn stride(&self) -> c_int

Get the image stride in number of bytes.

fn size(&self) -> &FastImageSize

Get the image size in number of pixels.

Provided Methods

fn width(&self) -> c_int

Get the image width in number of pixels.

fn height(&self) -> c_int

Get the image height in number of pixels.

fn valid_row_iter( &self, size: &FastImageSize ) -> Result<ValidChunksExact<'_, Self::D>>

Iterate over elements in each image row. Returns valid slices.

fn pixel_slice(&self, row: usize, col: usize) -> &[Self::D]

Get the raw data for a pixel.

Trait Implementations

impl ImageData<Mono8> for &dyn FastImage<D = u8, C = Chan1>

fn width(&self) -> u32

Number of pixel columns in the image. Note: this is not the stride.

fn height(&self) -> u32

Number of pixel rows in the image.

fn buffer_ref(&self) -> ImageBufferRef<'_, Mono8>

Returns the image buffer specified by pixel format F.

fn buffer(self) -> ImageBuffer<Mono8>

Returns the image buffer specified by pixel format F.

fn image_data(&self) -> &[u8]

Returns the raw image data as specified by pixel format F.

impl<C, D> Stride for &dyn FastImage<C = C, D = D>

where C: 'static + ChanTrait, D: 'static + Copy,

fn stride(&self) -> usize

the width (in bytes) of each row of image data
