# 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 - Font and Text Rendering ## 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 / 2; double center_y = height / 2; double radius = 70; double eye_radius = 10; 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_arc(pluto, center_x, center_y, radius, 0, 2 * pi, 0); plutovg_set_source_rgb(pluto, 1, 1, 0); plutovg_fill_preserve(pluto); plutovg_set_line_width(pluto, 5); plutovg_set_source_rgb(pluto, 0, 0, 0); plutovg_stroke(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_set_source_rgb(pluto, 0, 0, 0); plutovg_fill(pluto); plutovg_arc(pluto, center_x, center_y, 50, 0, pi, 0); plutovg_set_source_rgb(pluto, 0, 0, 0); plutovg_stroke(pluto); plutovg_surface_write_to_png(surface, "smiley.png"); plutovg_surface_destroy(surface); plutovg_destroy(pluto); return 0; } ``` output :  ## Build Install [cmake](https://cmake.org/download/) if not already installed ``` mkdir build cd build cmake .. make ``` ## Projects using PlutoVG - [LunaSVG](https://github.com/sammycage/lunasvg) - [PlutoSVG](https://github.com/sammycage/plutosvg) ## Support If you like what we do, [you can buy us a coffee](https://www.patreon.com/sammycage)
