Anti-Aliasing

Smooth rendering of edges and text.

Modes

Test Determinism

For reproducible tests, use grayscale only:

// Test configuration
let config = RenderConfig {
    antialiasing: Antialiasing::Grayscale,
    dpi: 1.0,  // Fixed DPI
};

Text Rendering

// Grayscale antialiasing for text
canvas.draw_text_aa(&text, position, &style, Antialiasing::Grayscale);

Shape Edges

// Antialiased rectangle
canvas.fill_rect_aa(bounds, color, Antialiasing::Grayscale);

Why Grayscale for Tests?

Verified Test

#[test]
fn test_antialiasing_determinism() {
    // Grayscale AA is deterministic
    let config_a = presentar_core::Color::new(0.5, 0.5, 0.5, 1.0);
    let config_b = presentar_core::Color::new(0.5, 0.5, 0.5, 1.0);

    assert_eq!(config_a, config_b);  // Same gray = deterministic
}
