Struct PdfRenderer 

pub struct PdfRenderer { /* private fields */ }

A renderer that produces PDF output.

Uses printpdf’s PdfDocument / PdfPage / PdfLayer model. All plotkit coordinates (origin top-left, y-down) are converted to PDF coordinates (origin bottom-left, y-up) during rendering.

Implementations

impl PdfRenderer

pub fn new(width: u32, height: u32) -> Self

Creates a new PDF renderer with the given dimensions in pixels.

A single PDF page is created with dimensions matching the pixel size at 72 DPI.

Trait Implementations

impl Renderer for PdfRenderer

fn size(&self) -> (u32, u32)

Returns the output dimensions in pixels.

fn fill_path(&mut self, path: &Path, paint: &Paint, transform: Affine)

Fills a path with the given paint, under the given transform.

fn stroke_path( &mut self, path: &Path, paint: &Paint, stroke: &Stroke, transform: Affine, )

Strokes a path with the given paint and stroke style, under the given transform.

fn draw_text( &mut self, text: &str, pos: Point, style: &TextStyle, transform: Affine, )

Draws text at the given position with the given style, under the given transform.

fn draw_image(&mut self, _img: &Image, _dst: Rect, _transform: Affine)

Draws a raster image into the destination rectangle, under the given transform.

fn push_clip(&mut self, path: &Path, transform: Affine)

Pushes a clipping path. All subsequent draws are clipped to this path.

fn pop_clip(&mut self)

Pops the most recent clipping path.

fn measure_text(&self, text: &str, style: &TextStyle) -> (f64, f64)

Measures the bounding box of the given text with the given style. Returns the width and height in pixels.

fn finalize(self) -> Vec<u8>

Consumes the renderer and returns the encoded output (PNG bytes, SVG string as bytes, etc.).
