Struct TextFlowContext 

pub struct TextFlowContext { /* private fields */ }

Implementations

impl TextFlowContext

pub fn new(page_width: f64, page_height: f64, margins: Margins) -> Self

pub fn set_font(&mut self, font: Font, size: f64) -> &mut Self

pub fn set_line_height(&mut self, multiplier: f64) -> &mut Self

pub fn set_alignment(&mut self, alignment: TextAlign) -> &mut Self

pub fn set_fill_color(&mut self, color: Color) -> &mut Self

Sets the non-stroking (fill) color used for subsequent text emitted by write_wrapped (issue #216). Mirrors TextContext::set_fill_color. None keeps the surrounding graphics state untouched (previous behaviour); Some(color) emits the matching PDF operator inside each BT … ET block.

pub fn set_character_spacing(&mut self, spacing: f64) -> &mut Self

Setters for the remaining text-state parameters, mirroring TextContext. Closes the propagation gap reported in issue #222. All apply on the next BT … ET block emitted by write_wrapped.

pub fn set_word_spacing(&mut self, spacing: f64) -> &mut Self

pub fn set_horizontal_scaling(&mut self, scale: f64) -> &mut Self

Set horizontal scaling. The argument is the ratio (e.g. 0.85 for 85 %); it is converted to the PDF Tz percentage at emission time. Matches the contract documented on TextContext::set_horizontal_scaling.

pub fn set_leading(&mut self, leading: f64) -> &mut Self

pub fn set_text_rise(&mut self, rise: f64) -> &mut Self

pub fn set_rendering_mode(&mut self, mode: u8) -> &mut Self

Set the text rendering mode (0..=7 per ISO 32000-1 §9.3.6). The argument is taken as a u8 rather than the typed TextRenderingMode enum to avoid an extra public dependency from TextFlowContext on the parent module.

pub fn set_stroke_color(&mut self, color: Color) -> &mut Self

pub fn current_font(&self) -> &Font

Current font this context will use when emitting text.

pub fn font_size(&self) -> f64

Current font size in points.

pub fn fill_color(&self) -> Option<Color>

Current fill color, if one has been explicitly set (issue #216).

pub fn at(&mut self, x: f64, y: f64) -> &mut Self

pub fn content_width(&self) -> f64

pub fn available_width(&self) -> f64

Returns the width available for text starting at the current cursor_x position.

Unlike content_width() which always uses margins.left as the origin, available_width() accounts for the actual cursor position so that text placed via .at(x, y) does not overflow the right margin.

pub fn write_wrapped(&mut self, text: &str) -> Result<&mut Self>

pub fn write_paragraph(&mut self, text: &str) -> Result<&mut Self>

pub fn newline(&mut self) -> &mut Self

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

pub fn generate_operations(&self) -> Vec<u8>

pub fn alignment(&self) -> TextAlign

Get the current alignment

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

Get the page dimensions

pub fn margins(&self) -> &Margins

Get the margins

pub fn line_height(&self) -> f64

Get current line height multiplier

pub fn operations(&self) -> String

Get the operations as a serialised PDF content-stream String.

Pre-2.7.0 this returned &str. The IR migration replaced the internal String buffer with a typed Vec<Op>, so the legacy borrow is materialised on demand. Internal callers prefer generate_operations() which returns the byte buffer directly.

pub fn clear(&mut self)

Clear all operations
