Struct RgbaSlice 

pub struct RgbaSlice<'a> { /* private fields */ }

Wraps &[[u8; 4]] (contiguous sRGBA pixels) with width and height.

Implementations

impl<'a> RgbaSlice<'a>

pub fn try_new( data: &'a [[u8; 4]], width: usize, height: usize, ) -> Result<Self, ZensimError>

Create a new RgbaSlice from contiguous [R,G,B,A] pixels.

Defaults to AlphaMode::Straight. Use try_with_alpha_mode or with_alpha_mode for explicit control.

Returns ZensimError::InvalidDataLength if data.len() < width * height.

pub fn new(data: &'a [[u8; 4]], width: usize, height: usize) -> Self

Create a new RgbaSlice from contiguous [R,G,B,A] pixels.

Defaults to AlphaMode::Straight. Use with_alpha_mode for explicit control.

Panics

Panics if data.len() < width * height.

pub fn try_with_alpha_mode( data: &'a [[u8; 4]], width: usize, height: usize, alpha_mode: AlphaMode, ) -> Result<Self, ZensimError>

Create a new RgbaSlice with an explicit alpha mode.

Returns ZensimError::InvalidDataLength if data.len() < width * height.

pub fn with_alpha_mode( data: &'a [[u8; 4]], width: usize, height: usize, alpha_mode: AlphaMode, ) -> Self

Create a new RgbaSlice with an explicit alpha mode.

Panics

Panics if data.len() < width * height.

Trait Implementations

impl<'a> Clone for RgbaSlice<'a>

fn clone(&self) -> RgbaSlice<'a>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a> Debug for RgbaSlice<'a>

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

Formats the value using the given formatter.

impl ImageSource for RgbaSlice<'_>

fn width(&self) -> usize

Image width in pixels.

fn height(&self) -> usize

Image height in pixels.

fn pixel_format(&self) -> PixelFormat

Pixel format (layout, bit depth, transfer function).

fn alpha_mode(&self) -> AlphaMode

Alpha channel interpretation.

fn row_bytes(&self, y: usize) -> &[u8]

Raw bytes for row y. Length must be at least width() * pixel_format().bytes_per_pixel().
