Struct SpanImageResample 

pub struct SpanImageResample<'a, I> { /* private fields */ }

Image resampling state for generic (non-affine) interpolators.

Unlike the affine variant which computes scale once per scanline, this version expects per-pixel scale values and provides adjust_scale() to clamp and blur them.

Port of C++ span_image_resample<Source, Interpolator>.

Implementations

impl<'a, I> SpanImageResample<'a, I>

pub fn new(interpolator: &'a mut I, filter: &'a ImageFilterLut) -> Self

Create with interpolator and filter.

pub fn base(&self) -> &SpanImageFilterBase<'a, I>

pub fn base_mut(&mut self) -> &mut SpanImageFilterBase<'a, I>

pub fn scale_limit(&self) -> i32

pub fn set_scale_limit(&mut self, v: i32)

pub fn blur_x(&self) -> f64

pub fn blur_y(&self) -> f64

pub fn set_blur_x(&mut self, v: f64)

pub fn set_blur_y(&mut self, v: f64)

pub fn set_blur(&mut self, v: f64)

pub fn adjust_scale(&self, rx: &mut i32, ry: &mut i32)

Adjust per-pixel scale factors: clamp to limits, apply blur.

Port of C++ span_image_resample::adjust_scale().
