A positioned run of extracted text.

Fields

text: String

The decoded text.

x: f32

Device-space x coordinate of the span origin.

y: f32

Device-space y coordinate of the span baseline.

end_x: f32

Device-space x after the last glyph’s advance.

size: f32

Effective font size.

font: String

Font resource name.

font_name: String

The font’s /BaseFont name verbatim — subset prefix included — falling back to the FontDescriptor’s /FontName; empty when the file names the font nowhere (a missing font resource included).

page: usize

0-based index of the page the span came from.

bbox: Rect

Device-space box: origin to advance horizontally, the font’s /Descent../Ascent (per-mille of the effective size) vertically. Exact for unrotated horizontal text, an approximation under rotated matrices; vertical writing takes the advance as its vertical extent and half the size to each side of the baseline.

bold: bool

Whether the font that produced this span is bold: FontDescriptor /FontWeight >= 600, /Flags ForceBold, or a /StemV in bold stem-width territory, else a Bold substring in /BaseFont (ISO 32000-1 Table 123).

italic: bool

Whether the font that produced this span is italic: FontDescriptor /Flags Italic or a nonzero /ItalicAngle, else an Italic or Oblique substring in /BaseFont (ISO 32000-1 Table 123).

monospace: bool

FontDescriptor /Flags FixedPitch (ISO 32000-1 Table 123 bit 1).

serif: bool

FontDescriptor /Flags Serif (ISO 32000-1 Table 123 bit 2).

rise: f32

The text rise (Ts) the span was shown under, in unscaled text space: positive above the baseline — a superscript/subscript signal. The origin already includes the shift.

vertical: bool

Writing mode 1: the text advances downward and bbox takes the advance as its vertical extent.

invisible: bool

Shown under render mode 3 or 7 (ISO 32000-1 Table 106), which paint nothing — the shape of an OCR text layer under a scanned image.

color: Option<(f32, f32, f32)>

The fill color the span was shown with, as RGB in [0, 1]. Device gray/RGB/CMYK convert exactly; other spaces’ components are read by count (1 gray, 3 RGB, 4 CMYK) without running the space’s transform. None for pattern fills, which have no single color.

underline: bool

A drawn ruling sits just below the baseline and covers most of the span. PDF has no underline attribute — this is read from the page’s geometry, so a table border hugging a cell’s text can read as one.

strikethrough: bool

A drawn ruling crosses the span’s x-height band — geometry-read, like underline.
