Struct ImageView 

pub struct ImageView<'a> {
    pub data: &'a [u8],
    pub width: usize,
    pub height: usize,
    /* private fields */
}

Minimal grayscale view for refinement without taking a dependency on image.

Fields

data: &'a [u8]

width: usize

height: usize

Implementations

impl<'a> ImageView<'a>

pub fn from_u8_slice( width: usize, height: usize, data: &'a [u8], ) -> Option<ImageView<'a>>

pub fn with_origin( width: usize, height: usize, data: &'a [u8], origin: [i32; 2], ) -> Option<ImageView<'a>>

pub fn origin(&self) -> [i32; 2]

Return the view’s origin in the coordinate system of the response map / base image. Use Self::with_origin to construct a view with a non-zero origin.

pub fn supports_patch(&self, cx: i32, cy: i32, radius: i32) -> bool

pub fn sample(&self, gx: i32, gy: i32) -> f32

pub fn sample_bilinear(&self, gx: f32, gy: f32) -> f32

Bilinear sample at subpixel coordinates. Coordinates are in the view’s external frame (same as Self::sample): origin is applied, then the sample is clamped to the valid pixel range.

Trait Implementations

impl<'a> Clone for ImageView<'a>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for ImageView<'a>

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

Formats the value using the given formatter.

impl<'a> Copy for ImageView<'a>
