Tamin'ny 11 martsa, nisy ny famoahana lehibe voalohany ny 1.0.0 amin'ny tranomboky sary vetaveta XNUMXD PlutoVG, voasoratra amin'ny teny C ary zaraina amin'ny alalan'ny lisansa MIT. Tsy misy fiankinan-doha amin'ny antoko fahatelo ny tranomboky.
Toetran'ny tranomboky:
- fomba fanaovana tsipika;
- alokaloka mafy orina, gradient ary textured;
- endri-tsoratra sy lahatsoratra;
- fanetezam-boaloboka sy composition;
- fiovana;
- iconography.
Ny tranomboky dia ampiasaina amin'ny tetikasa hafa an'ny mpanoratra: LunaSVG и PlutoSVG.
Fiovana:
- ny fampiasana ny SemVer ho an'ny laharana laharana.
- Nampiana macro PLUTOVG_EMPTY_POINT sy PLUTOVG_EMPTY_RECT.
code:
#ao anatin'izany int main(void) { const int sakany = 150; const int haavony = 150; const float center_x = sakany / 2.f; const float center_y = haavo / 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 = centre_x — eye_offset_x; const float eye_y = centre_y — eye_offset_y; plutovg_surface_t* surface = plutovg_surface_create(sakany, haavony); 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, centre_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); miverina 0; }
misintona 😃 ary mitahiry izany ao amin'ny rakitra smiley.png. 🙂
