Sina - سینا

A modern 2D graphics rendering engine written in pure Rust, inspired by Skia.

✨ Features

• ✅ Pure Rust: No C/C++ dependencies, fully memory-safe
• ✅ Vector Graphics: Path rendering with Bezier curves
• ✅ Text Rendering: TrueType (.ttf) and OpenType (.otf) font support
• ✅ Complex Scripts: Arabic, Hebrew, CJK, and more via rustybuzz
• ✅ Multiple Backends: CPU (software) and GPU (WebGPU - planned)
• ✅ High Performance: SIMD optimizations and glyph caching
• ✅ Clean API: Ergonomic, Rust-idiomatic interface

🚀 Quick Start

Add Sina to your Cargo.toml:

[dependencies]
sina = "0.1.0"

Drawing Shapes

use sina::{Color, Paint, Point, Rect, Surface, CpuSurface};

fn main() -> Result<(), Box<dyn std::error::Error>> {
    let mut surface = CpuSurface::new(800, 600);
    surface.canvas().clear(Color::WHITE);

    // Draw shapes
    let paint = Paint::with_color(Color::RED);
    surface.canvas().draw_rect(Rect::new(100.0, 100.0, 200.0, 150.0), &paint);

    surface.save_png("output.png")?;
    Ok(())
}

Drawing Text

use sina::{Color, Paint, Point, Surface, CpuSurface, Font};

fn main() -> Result<(), Box<dyn std::error::Error>> {
    let mut surface = CpuSurface::new(800, 400);
    let font = Font::from_file("/usr/share/fonts/truetype/dejavu/DejaVuSans.ttf")?;

    let paint = Paint::with_color(Color::rgb(40, 40, 40));
    surface.canvas().draw_text(
        "Hello, Sina! مرحبا שלום",
        Point::new(50.0, 150.0),
        &font,
        48.0,
        &paint,
    );

    surface.save_png("text.png")?;
    Ok(())
}

📦 Project Structure

• sina: All-in-one rendering engine
  • Core types (geometry, color, paint, path, surface)
  • CPU backend (raqote software rasterizer)
  • Text rendering (fontdue + rustybuzz)
  • GPU backend (wgpu - planned)

� Examples
