Implementations§

Source §

impl GraphicsState

Source

pub fn begin_text(&mut self)

Begin text object: reset text matrix and text line matrix.

Source

pub fn text_rendering_matrix(&self) -> Matrix

Get the combined text rendering matrix: text_state.font_size × text_matrix × CTM.

Source

pub fn text_position(&self) -> (f64, f64)

Get the current text position in user space.

Source

pub fn effective_font_size(&self) -> f64

Get the effective font size in user space.

Source

pub fn translate_text(&mut self, tx: f64, ty: f64)

Apply Td (translate text position).

Source

pub fn set_text_matrix( &mut self, a: f64, b: f64, c: f64, d: f64, e: f64, f: f64, )

Apply Tm (set text matrix directly).

Source

pub fn next_line(&mut self)

Apply T* (move to start of next line).

Source

pub fn advance_text(&mut self, displacement: f64)

Advance the text position after showing text (Tj displacement).
