Struct BaFontMap 

pub struct BaFontMap { /* private fields */ }

Font map for form field appearance streams.

Resolves font resources from the interactive form’s /DR dictionary and the field’s /DA (default appearance) string.

Implementations

impl BaFontMap

pub fn from_resources<S: PdfSource>( dr_dict: Option<&HashMap<Name, Object>>, da_string: Option<&str>, store: &ObjectStore<S>, ) -> Self

Build a font map from the form’s /DR dictionary and /DA string.

dr_dict is the Font sub-dictionary from /DR → /Font. da_string is the default appearance string (e.g., “0 g /Helv 12 Tf”).

pub fn default_font_name(&self) -> Option<&str>

Return the default font name from /DA.

pub fn default_font_size(&self) -> f32

Return the default font size from /DA.

pub fn font_count(&self) -> usize

Return the number of available fonts.

pub fn font_name(&self, index: usize) -> Option<&str>

Return the font name at the given index.

pub fn get_font_name(&self, index: usize) -> Option<&str>

Upstream-aligned alias for font_name.

pub fn charset(&self, index: usize) -> Option<u8>

Return the charset of the font at the given index.

pub fn get_charset(&self, index: usize) -> Option<u8>

Upstream-aligned alias for charset.

pub fn find_font(&self, name: &str) -> Option<&BaFontMapEntry>

Find a font entry by name.

pub fn entries(&self) -> &[BaFontMapEntry]

Return all font entries.

pub fn find_font_or_fallback(&self, name: &str) -> Option<&BaFontMapEntry>

Find a font entry by name, falling back to standard font name aliases.

Tries the exact name first, then checks common abbreviation/alias mappings:

• “Helv” ↔ “Helvetica”
• “Cour” ↔ “Courier”
• “TiRo” ↔ “TimesNewRoman” / “Times-Roman”
• “ZaDb” ↔ “ZapfDingbats”
