pub struct ImageView<'a, T, const CHANNELS: usize> { /* private fields */ }Expand description
A read-only, zero-copy image view with an explicit row stride.
Implementations§
Source§impl<'a, T, const CHANNELS: usize> ImageView<'a, T, CHANNELS>
impl<'a, T, const CHANNELS: usize> ImageView<'a, T, CHANNELS>
Sourcepub fn new(
width: usize,
height: usize,
row_stride: usize,
data: &'a [T],
) -> Result<ImageView<'a, T, CHANNELS>, ImageError>
pub fn new( width: usize, height: usize, row_stride: usize, data: &'a [T], ) -> Result<ImageView<'a, T, CHANNELS>, ImageError>
Creates a view over interleaved storage.
row_stride is measured in scalar elements, not bytes.
Sourcepub fn new_with_metadata(
width: usize,
height: usize,
row_stride: usize,
data: &'a [T],
metadata: ImageMetadata,
) -> Result<ImageView<'a, T, CHANNELS>, ImageError>
pub fn new_with_metadata( width: usize, height: usize, row_stride: usize, data: &'a [T], metadata: ImageMetadata, ) -> Result<ImageView<'a, T, CHANNELS>, ImageError>
Creates a view with validated semantic metadata.
Sourcepub const fn row_stride(self) -> usize
pub const fn row_stride(self) -> usize
Returns row stride in scalar elements.
Sourcepub const fn layout(self) -> ImageLayout
pub const fn layout(self) -> ImageLayout
Returns physical channel layout.
Sourcepub const fn metadata(self) -> ImageMetadata
pub const fn metadata(self) -> ImageMetadata
Returns semantic image metadata.
Sourcepub fn get(self, x: usize, y: usize) -> Option<&'a [T; CHANNELS]>
pub fn get(self, x: usize, y: usize) -> Option<&'a [T; CHANNELS]>
Returns one pixel, or None outside image bounds.
Sourcepub fn row(self, y: usize) -> Option<&'a [T]>
pub fn row(self, y: usize) -> Option<&'a [T]>
Returns a packed row without its trailing padding.
Sourcepub fn subview(
self,
region: ImageRegion,
) -> Result<ImageView<'a, T, CHANNELS>, ImageError>
pub fn subview( self, region: ImageRegion, ) -> Result<ImageView<'a, T, CHANNELS>, ImageError>
Creates a checked zero-copy subview.
