graphitepdf-renderer 0.2.0

Overview

graphitepdf-renderer provides the higher-level rendering facade for GraphitePDF and re-exports the rendering surface from graphitepdf-render.

Scope

graphitepdf-renderer contains:

• re-exported render-session and backend APIs from graphitepdf-render
• output-oriented helpers for bytes, writers, and files
• examples that demonstrate the split layout -> render -> renderer flow

Installation

cargo add graphitepdf-renderer

API Summary

Example

use graphitepdf_font::{FontSource, StandardFont};
use graphitepdf_layout::{Document, LayoutStyle, Node, Page};
use graphitepdf_primitives::Pt;
use graphitepdf_renderer::render_to_bytes;
use graphitepdf_textkit::{TextBlock, TextSpan};

fn main() -> Result<(), Box<dyn std::error::Error>> {
    let body = TextBlock::from(TextSpan::new("Renderer facade")?);
    let document = Document::new().with_page(
        Page::new([
            Node::text(body).with_style(
                LayoutStyle::new()
                    .with_font_family("Helvetica")
                    .with_font_source(FontSource::standard(StandardFont::Helvetica))
                    .with_font_size(Pt::new(12.0)),
            ),
        ]),
    );

    let pdf = render_to_bytes(&document)?;
    assert!(pdf.starts_with(b"%PDF-1.7"));
    Ok(())
}

Design Principles

• keep the crate thin and output-focused
• mirror the underlying render APIs instead of inventing a second rendering engine
• provide a friendly entry point for callers that want session-style rendering
• stay aligned with the canonical render crate rather than diverging from it

Role In GraphitePDF

This crate sits above graphitepdf-render as a convenience facade. The substantive rendering logic still lives in render.
