    state: Rc<RefCell<OcrState>>,
}

Implementations

impl OcrLayer

pub(crate) fn new() -> Self

pub(super) fn set_boxes(&self, boxes: Vec<OcrBox>, image: (f64, f64))

Replaces the boxes and clears the selection; image is the displayed texture’s size.

pub(crate) fn clear(&self)

pub(super) fn has_boxes(&self) -> bool

pub(super) fn box_at(&self, p: (f64, f64)) -> Option<usize>

Box under p, given in this area’s coordinates.

pub(super) fn set_hovered(&self, idx: Option<usize>) -> bool

Returns whether the hovered box changed.

pub(super) fn press(&self, idx: usize, shift: bool, ctrl: bool) -> bool

Mouse press on a box; returns whether dragging should extend the selection.

pub(super) fn click(&self, idx: usize, extend: bool)

pub(super) fn extend_to(&self, idx: usize)

pub(super) fn has_selection(&self) -> bool

pub(super) fn all_text(&self) -> Option<String>

pub(super) fn select_all(&self)

pub(super) fn clear_selection(&self)

pub(super) fn selected_text(&self) -> Option<String>

pub(super) fn text_at(&self, idx: usize) -> Option<String>
