Struct BoundingBox 

pub struct BoundingBox {
    pub page_number: Option<u32>,

    pub left_x: f64,
    pub bottom_y: f64,
    pub right_x: f64,

}

A rectangular bounding box in PDF coordinate space.

PDF coordinates: origin at bottom-left, Y increases upward. 72 points = 1 inch.

Implementations

impl BoundingBox

pub fn new( page: Option<u32>, left_x: f64, bottom_y: f64, right_x: f64, top_y: f64, ) -> Self

Create a new BoundingBox.

pub fn empty() -> Self

Create an empty bounding box (zero area at origin).

pub fn width(&self) -> f64

Width of the bounding box.

pub fn height(&self) -> f64

Height of the bounding box.

pub fn area(&self) -> f64

Area of the bounding box.

pub fn center_x(&self) -> f64

Center X coordinate.

pub fn center_y(&self) -> f64

Center Y coordinate.

pub fn is_empty(&self) -> bool

Whether this bounding box has zero or negative area.

pub fn is_one_page(&self) -> bool

Whether this element is on a single page.

pub fn is_multi_page(&self) -> bool

Whether this element spans multiple pages.

pub fn normalize(&mut self)

Normalize: ensure left < right and bottom < top.

pub fn union(&self, other: &BoundingBox) -> BoundingBox

Compute the union of two bounding boxes.

pub fn overlaps(&self, other: &BoundingBox) -> bool

Whether this bounding box overlaps with another.

pub fn contains(&self, other: &BoundingBox) -> bool

Whether this bounding box fully contains another.

pub fn weakly_contains(&self, other: &BoundingBox) -> bool

Weakly contains: allows small margin of error.

pub fn intersection_percent(&self, other: &BoundingBox) -> f64

Compute intersection area percentage relative to other.

pub fn vertical_intersection_percent(&self, other: &BoundingBox) -> f64

Vertical intersection percentage.

pub fn vertical_gap(&self, other: &BoundingBox) -> f64

Vertical gap between two bounding boxes.

pub fn horizontal_gap(&self, other: &BoundingBox) -> f64

Horizontal gap between two bounding boxes.

pub fn are_horizontal_overlapping(&self, other: &BoundingBox) -> bool

Whether two bounding boxes horizontally overlap.

pub fn are_vertical_overlapping(&self, other: &BoundingBox) -> bool

Whether two bounding boxes vertically overlap.

pub fn scale(&mut self, factor: f64)

Scale the bounding box by a factor.

pub fn translate(&mut self, dx: f64, dy: f64)

Translate the bounding box by (dx, dy).

pub fn to_json_array(&self) -> [f64; 4]

Serialize to JSON array format: [leftX, bottomY, rightX, topY]

Trait Implementations

impl Clone for BoundingBox

fn clone(&self) -> BoundingBox

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for BoundingBox

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for BoundingBox

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for BoundingBox

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for BoundingBox

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
