Struct TextBlock 

pub struct TextBlock {
    pub spans: Vec<TextSpan>,
}

A block of text (grouped by reading order).

Fields

spans: Vec<TextSpan>

Spans within this block, sorted by position.

Implementations

impl TextBlock

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

Enclosing box of the block’s spans, [x_min, y_min, x_max, y_max] in PDF points. A block with no spans has the box [0, 0, 0, 0].

pub fn text(&self) -> String

Concatenate all spans into a single string, in reading order.

Spans that are close together are joined without a separator; a space is inserted when the gap between spans exceeds half the average character width.

ANN[r17/TEX5] The spans are in the order the page draws them, left to right, and for Arabic or Hebrew that is the reverse of the order they are read in (#436, class R-H of #389). The assembled line therefore goes through [crate::bidi::logical_order] before it is returned: a line with no right-to-left character comes back untouched, and one that has them comes back with each of its runs the way a reader would type it. The spans themselves are left alone – they carry the geometry, and the geometry is visual.
