On March 11, the first significant release of version 1.0.0 of the two-dimensional vector graphics library PlutoVG, written in C and distributed under the MIT License. The library has no external dependencies.
Library capabilities:
- line drawing styles;
- solid, gradient, and textured filling;
- fonts and text;
- clipping and compositing;
- transformations;
- images.
The library is used in other projects by the author: LunaSVG and PlutoSVG.
Changes:
- Using SemVer for version numbering.
- Added macros PLUTOVG_EMPTY_POINT and PLUTOVG_EMPTY_RECT.
Code:
#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; }
draws 😃 and saves it in the file smiley.png. 🙂
