Struct FixedPrintSpec 

pub struct FixedPrintSpec {
    pub matrix: Option<[f32; 6]>,
    pub h: Option<f32>,
    pub v: Option<f32>,
}

/FixedPrint sub-dict for AnnotationKind::Watermark (ISO 32000-1 §12.5.6.22 Table 191, round 252). Every field is optional with an explicit Table 191 default; the writer omits each entry whose value equals the default so a write-then-read cycle through the round-204 read_pdf_annotations enumerator yields the same “absent → default” reader shape producer files use.

Mirrors the reader-side crate::FixedPrint decoded struct shape so callers can copy fields directly between the two when manipulating existing watermarks.

Default-constructed (FixedPrintSpec::default()) sets every entry to None so the writer emits the bare /Type /FixedPrint marker dict — the most-minimal way to opt a Watermark in to media-relative rendering without overriding any geometry.

Fields

matrix: Option<[f32; 6]>

/Matrix [a b c d e f] — affine transform applied to the annotation rectangle before rendering. None ⇒ writer omits the entry (Table 191 default is the identity matrix [1 0 0 1 0 0]).

h: Option<f32>

/H — horizontal translation as a fraction of the target media width (1.0 = 100 %, 0.0 = 0 %). None ⇒ writer omits the entry (Table 191 default 0).

v: Option<f32>

/V — vertical translation as a fraction of the target media height. None ⇒ writer omits the entry (Table 191 default 0).

Trait Implementations

impl Clone for FixedPrintSpec

fn clone(&self) -> FixedPrintSpec

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FixedPrintSpec

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

Formats the value using the given formatter.

impl Default for FixedPrintSpec

fn default() -> FixedPrintSpec

Returns the “default value” for a type.

impl PartialEq for FixedPrintSpec

fn eq(&self, other: &FixedPrintSpec) -> 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.
