## Example
|
|
```c
|
|
#include <plutovg.h>
|
|
|
|
int main(void)
|
|
{
|
|
const int width = 150;
|
|
const int height = 150;
|
|
|
|
const float center_x = width / 2.f;
|
|
const float center_y = height / 2.f;
|
|
const float face_radius = 70;
|
|
const float mouth_radius = 50;
|
|
const float eye_radius = 10;
|
|
const float eye_offset_x = 25;
|
|
const float eye_offset_y = 20;
|
|
const float eye_x = center_x - eye_offset_x;
|
|
const float eye_y = center_y - eye_offset_y;
|
|
|
|
plutovg_surface_t* surface = plutovg_surface_create(width, height);
|
|
plutovg_canvas_t* canvas = plutovg_canvas_create(surface);
|
|
|
|
plutovg_canvas_save(canvas);
|
|
plutovg_canvas_arc(canvas, center_x, center_y, face_radius, 0, PLUTOVG_TWO_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, PLUTOVG_TWO_PI, 0);
|
|
plutovg_canvas_arc(canvas, center_x + eye_offset_x, eye_y, eye_radius, 0, PLUTOVG_TWO_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, PLUTOVG_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_canvas_destroy(canvas);
|
|
plutovg_surface_destroy(surface);
|
|
return 0;
