# PlutoVG
PlutoVG is a standalone 2D vector graphics library in C.
## Features
- Path Filling, Stroking and Dashing
- Soild, Gradient and Texture Paints
- Clipping and Compositing
- Transformations
## Example
```c
#include "plutovg.h"
int main(void)
{
const int width = 150;
const int height = 150;
plutovg_surface_t* surface = plutovg_surface_create(width, height);
plutovg_t* pluto = plutovg_create(surface);
double center_x = width * 0.5;
double center_y = height * 0.5;
double face_radius = 70;
double eye_radius = 10;
double mouth_radius = 50;
double eye_offset_x = 25;
double eye_offset_y = 20;
double eye_x = center_x - eye_offset_x;
double eye_y = center_y - eye_offset_y;
const double pi = 3.14159265358979323846;
plutovg_save(pluto);
plutovg_arc(pluto, center_x, center_y, face_radius, 0, 2 * pi, 0);
plutovg_set_rgb(pluto, 1, 1, 0);
plutovg_fill_preserve(pluto);
plutovg_set_rgb(pluto, 0, 0, 0);
plutovg_set_line_width(pluto, 5);
plutovg_stroke(pluto);
plutovg_restore(pluto);
plutovg_save(pluto);
plutovg_arc(pluto, eye_x, eye_y, eye_radius, 0, 2 * pi, 0);
plutovg_arc(pluto, center_x + eye_offset_x, eye_y, eye_radius, 0, 2 * pi, 0);
plutovg_fill(pluto);
plutovg_restore(pluto);
plutovg_save(pluto);
plutovg_arc(pluto, center_x, center_y, mouth_radius, 0, pi, 0);
plutovg_set_line_width(pluto, 5);
plutovg_stroke(pluto);
plutovg_restore(pluto);
plutovg_surface_write_to_png(surface, "smiley.png");
plutovg_surface_destroy(surface);
plutovg_destroy(pluto);
return 0;
}
```
