Enum Alignment 

pub enum Alignment {
    Left,
    Center,
    Right,
}

How a line sits within the plate.

use pdfrum_doc::vt::Alignment;

// `/Q` names the three, and the default is flush left.
assert_eq!(Alignment::default(), Alignment::Left);
assert_eq!(Alignment::from_quadding(1), Alignment::Center);

Variants

Left

Flush left.

Center

Centred.

Right

Flush right.

Implementations

impl Alignment

pub fn from_quadding(q: i64) -> Alignment

Reads a /Q value; anything outside 0..=2 is left-aligned.

use pdfrum_doc::vt::Alignment;

assert_eq!(Alignment::from_quadding(0), Alignment::Left);
assert_eq!(Alignment::from_quadding(2), Alignment::Right);
// Anything outside `0..=2` is left-aligned.
assert_eq!(Alignment::from_quadding(9), Alignment::Left);

pub fn to_quadding(self) -> i64

The /Q value for this alignment — the inverse of from_quadding over the three it names.

Reading is lenient where writing is not: from_quadding takes any unknown number as Left, so the round trip holds in this direction only.

use pdfrum_doc::vt::Alignment;

for alignment in [Alignment::Left, Alignment::Center, Alignment::Right] {
    assert_eq!(Alignment::from_quadding(alignment.to_quadding()), alignment);
}
