# PlutoVG

PlutoVG is a standalone 2D vector graphics library in C.

## Features

- Path Filling, Stroking and Dashing

- Soild, Gradient and Texture Paints

- Fonts and Texts

- Clipping and Compositing

- Transformations

- Images

## Example

```c

#include 

int main(void)

{

    const int width = 150;

    const int height = 150;

    plutovg_surface_t* surface = plutovg_surface_create(width, height);

    plutovg_canvas_t* canvas = plutovg_canvas_create(surface);

    float center_x = width * 0.5;

    float center_y = height * 0.5;

    float face_radius = 70;

    float eye_radius = 10;

    float mouth_radius = 50;

    float eye_offset_x = 25;

    float eye_offset_y = 20;

    float eye_x = center_x - eye_offset_x;

    float eye_y = center_y - eye_offset_y;

    const float pi = 3.14159265358979323846;

    plutovg_canvas_save(canvas);

    plutovg_canvas_arc(canvas, center_x, center_y, face_radius, 0, 2 * pi, 0);

    plutovg_canvas_set_rgb(canvas, 1, 1, 0);

    plutovg_canvas_fill_preserve(canvas);

    plutovg_canvas_set_rgb(canvas, 0, 0, 0);

    plutovg_canvas_set_line_width(canvas, 5);

    plutovg_canvas_stroke(canvas);

    plutovg_canvas_restore(canvas);

    plutovg_canvas_save(canvas);

    plutovg_canvas_arc(canvas, eye_x, eye_y, eye_radius, 0, 2 * pi, 0);

    plutovg_canvas_arc(canvas, center_x + eye_offset_x, eye_y, eye_radius, 0, 2 * pi, 0);

    plutovg_canvas_set_rgb(canvas, 0, 0, 0);

    plutovg_canvas_fill(canvas);

    plutovg_canvas_restore(canvas);

    plutovg_canvas_save(canvas);

    plutovg_canvas_arc(canvas, center_x, center_y, mouth_radius, 0, pi, 0);

    plutovg_canvas_set_rgb(canvas, 0, 0, 0);

    plutovg_canvas_set_line_width(canvas, 5);

    plutovg_canvas_stroke(canvas);

    plutovg_canvas_restore(canvas);

    plutovg_surface_write_to_png(surface, "smiley.png");

    plutovg_surface_destroy(surface);

    plutovg_canvas_destroy(canvas);

    return 0;

}

```

output :
