Enum PageRotation 

pub enum PageRotation {
    Upright,
    Ccw,
    Cw,
}

Which way a page’s coordinate frame was turned so that predominantly rotated text reads along +x.

A page whose text mostly runs vertically is re-based so its dominant runs read left-to-right: the items’ x/y/width/height and rotation are then expressed in the turned frame, not in page coordinates. Region boxes given in page coordinates must be turned the same way — collect_text_in_region_in_frame does that, and extract_text_with_positions_and_rotations_mem reports each page’s turn.

Variants

Upright

Text reads along +x; coordinates are plain page coordinates.

Ccw

Most runs read bottom-to-top (90°, Tm = [0 b -b 0]): the frame was turned so they read along +x, mapping (x, y) → (y, -x).

Cw

Most runs read top-to-bottom (270°, Tm = [0 -b b 0]): the frame was turned the other way, mapping (x, y) → (-y, x).
