Struct Layout 

pub struct Layout {
    pub frames: Vec<u32>,
    pub pos_of: HashMap<String, usize>,
}

Position <-> image name. Position = index in the selected frame list (not file number / stride).

Fields

frames: Vec<u32>

Frame number of the input file per position.

pos_of: HashMap<String, usize>

Image name -> position.

Implementations

impl Layout

pub fn discover(src: &Path, stride: usize) -> Result<Self, String>

Those of images/camF/camF_NNNN.jpg with number % stride == 0 (ascending number).

pub fn discover_in<S: AsRef<str>>( images: &Path, cams: &[S], stride: usize, ) -> Result<Self, String>

Those of the first camera folder of the image folder images (<cams[0]>/<cams[0]>_NNNN.jpg) with number % stride == 0 (ascending number). The name -> position table is built for all cameras.

pub fn truncate(&mut self, n: usize)

Keep only the first n positions.

pub fn name(&self, cam: &str, p: usize) -> String

Image name of a camera and position (cam/cam_NNNN.jpg).
