Struct ImageRefMut

pub struct ImageRefMut<'a, FMT: PixelFormat> { /* private fields */ }

A view of mutable image to have pixel format FMT.

Implementations

impl<'a, FMT: PixelFormat> ImageRefMut<'a, FMT>

pub fn new( width: u32, height: u32, stride: usize, buf: &'a mut [u8], ) -> Option<Self>

Use a &mut [u8] slice as the backing store for an ImageRefMut.

Returns None if the buffer is not large enough to store an image of the desired properties.

Trait Implementations

impl<F: PixelFormat> Debug for ImageRefMut<'_, F>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<FMT: PixelFormat> ImageData<FMT> for ImageRefMut<'_, FMT>

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<'_, FMT>

Returns the image buffer specified by pixel format F.

fn buffer(self) -> ImageBuffer<FMT>

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<FMT: PixelFormat> ImageMutData<FMT> for ImageRefMut<'_, FMT>

fn buffer_mut_ref(&mut self) -> ImageBufferMutRef<'_, FMT>

Returns the image mutable buffer specified by pixel format F.

impl<FMT: PixelFormat> Stride for ImageRefMut<'_, FMT>

fn stride(&self) -> usize

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