Struct tray_rust::sampler::Region

pub struct Region {
    pub current: (u32, u32),
    pub start: (u32, u32),
    pub end: (u32, u32),
    pub dim: (u32, u32),
}

Defines a region of the image being sampled in pixel coordinates

Fields

current: (u32, u32)

Current coordinates of the pixel to sample (x, y)

start: (u32, u32)

Coordinates of the start of region being sampled (x, y)

end: (u32, u32)

Coordinates of the end of the region being sampled (x, y)

dim: (u32, u32)

Dimensions of the region being sampled

Methods

impl Region

pub fn new(start: (u32, u32), dim: (u32, u32)) -> Region

Create a new region starting at start with dimension dim

pub fn select_region(&mut self, start: (u32, u32))

Select a new region starting at region indices start with the same dimensions eg. with blocks of width 8 the 2nd region along x is at 16 so to get this block you'd set start.0 = 2
