Struct visioncortex::Sampler

pub struct Sampler {
    pub image: BinaryImage,
}

For sampling and resizing binary images

Fields

image: BinaryImage

Implementations

impl Sampler

pub fn new(image: &BinaryImage) -> Sampler

pub fn new_with_size(image: &BinaryImage, sampler_size: usize) -> Sampler

pub fn new_with_size_crop( image: &BinaryImage, sampler_size: usize, crop: BoundingRect ) -> Sampler

pub fn resample_square_image( image: &BinaryImage, crop: BoundingRect, new_size: usize ) -> BinaryImage

Resize an image of any size into a square image while keeping the aspect ratio of content. Would empty fill expanded area.

pub fn resample_image( image: &BinaryImage, new_width: usize, new_height: usize ) -> BinaryImage

pub fn resample_image_with_crop( image: &BinaryImage, crop: BoundingRect, new_width: usize, new_height: usize ) -> BinaryImage

pub fn resample_image_with_crop_to_image( src: &BinaryImage, src_rect: BoundingRect, dst: &mut BinaryImage, dst_rect: BoundingRect )

pub fn resample_image_with_crop_to_image_overlay( src: &BinaryImage, src_rect: BoundingRect, dst: &mut BinaryImage, dst_rect: BoundingRect, overlay: bool )

impl Sampler

pub fn size(&self) -> usize

pub fn bounding_rect(&self) -> BoundingRect

pub fn sample( &self, left: usize, top: usize, right: usize, bottom: usize ) -> usize
