Struct convert_image::RoiImage

source · 
pub struct RoiImage<'a, F> { /* private fields */ }
Expand description

An RoiImage maintains a reference to the original image but views a subregion of the original data.

Implementations§

source§

impl<'a, F> RoiImage<'a, F>
where F: PixelFormat,

source

pub fn new( frame: &'a dyn ImageStride<F>, w: u32, h: u32, x: u32, y: u32 ) -> Result<RoiImage<'a, F>, Error>

Create a new RoiImage referencing the original frame.
