Struct TextSection 

pub struct TextSection<'f, 'p> {
    font_cache: &'f FontCache,
    area: Area<'p>,
    is_first: bool,
    cursor_y_positioned: bool,
    metrics: Metrics,
    font: Option<(IndirectFontRef, u8)>,
    current_x_offset: Mm,
    cumulative_kerning: Mm,
    first_char_offset: Mm,
}

A text section that is drawn on an area of a PDF layer.

Implementations

impl<'f, 'p> TextSection<'f, 'p>

fn new( font_cache: &'f FontCache, area: Area<'p>, metrics: Metrics, ) -> Option<TextSection<'f, 'p>>

fn set_text_cursor(&mut self, x_offset: Mm)

fn set_font(&mut self, font: &IndirectFontRef, font_size: u8)

pub fn add_newline(&mut self) -> bool

Tries to add a new line and returns true if the area was large enough to fit the new line.

pub fn print_str( &mut self, s: impl AsRef<str>, style: Style, ) -> Result<(), Error>

Prints the given string with the given style.

The font cache for this text section must contain the PDF font for the given style. Prints a string using the provided Style and font cache.

For built-in PDF fonts, the string is emitted as a single item and the PDF viewer’s native kerning and glyph selection is relied upon. For embedded (external) fonts we also emit the whole string as a single write op so that glyph selection and any ToUnicode mapping is handled by the PDF serializer/renderer. This avoids brittle glyph-id → byte encodings that can become invalid when fonts are subsetted/remapped during PDF serialization. (If finer-grained positioning is needed in the future we may add a TJ-based emission that preserves a single text object.)

pub fn add_link( &mut self, text: impl AsRef<str>, uri: impl AsRef<str>, style: Style, ) -> Result<(), Error>

Adds a clickable link with the given text, URI, and style.

The font cache for this text section must contain the PDF font for the given style.
