LowercaseRoman

Lowercase roman numerals (i, ii, iii, iv, …)

None

Implementations

impl PageLabelStyle

pub fn to_pdf_name(&self) -> Option<&'static str>

Convert to PDF name per ISO 32000-1 §12.4.2 Table 159.

Mapping:

• D — decimal arabic
• R — uppercase roman
• r — lowercase roman
• A — uppercase letters
• a — lowercase letters

A conforming viewer uses the /S name to decide the case of the rendered numeral, so this mapping must match the case implied by Self::format — otherwise the Rust side and the rendered PDF disagree on case.

pub fn format(&self, number: u32) -> String

Format a page number in this style
