Struct NearestResampler 

pub struct NearestResampler;

Nearest neighbor resampler

Implementations

impl NearestResampler

pub fn resample_simd( &self, src: &RasterBuffer, dst_width: u64, dst_height: u64, ) -> Result<RasterBuffer>

SIMD-accelerated resampling (when available)

This uses platform-specific SIMD instructions to process multiple pixels at once. Falls back to scalar implementation if SIMD is not available.

impl NearestResampler

pub const fn new() -> Self

Creates a new nearest neighbor resampler

pub fn resample( &self, src: &RasterBuffer, dst_width: u64, dst_height: u64, ) -> Result<RasterBuffer>

Resamples a raster buffer using nearest neighbor

Arguments

• src - Source raster buffer
• dst_width - Target width in pixels
• dst_height - Target height in pixels

Errors

Returns an error if:

• Target dimensions are zero
• Source buffer is invalid
• Memory allocation fails

pub fn resample_with_transform( &self, src: &RasterBuffer, dst_width: u64, dst_height: u64, scale_x: f64, scale_y: f64, offset_x: f64, offset_y: f64, ) -> Result<RasterBuffer>

Resamples with explicit scaling factors

This variant allows precise control over the resampling transformation.

Arguments

• src - Source raster buffer
• dst_width - Target width
• dst_height - Target height
• scale_x - Horizontal scaling factor
• scale_y - Vertical scaling factor
• offset_x - Horizontal offset in source coordinates
• offset_y - Vertical offset in source coordinates

Errors

Returns an error if parameters are invalid

pub fn resample_repeat( &self, src: &RasterBuffer, dst_width: u64, dst_height: u64, ) -> Result<RasterBuffer>

Resamples with repeat edge mode (instead of clamp)

When sampling outside the source bounds, this wraps coordinates rather than clamping them. Useful for tiled or periodic data.
