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
)
