efl_canvas_rectangle: rendering optmization.
There was a weird profiling result that rectangles drawing is much much slower than images. Checked reason, the computation rect clip area is the overload point. I don't think it's necesary but we can simplely improve the performance here by replacing native function. I tested this by drawing 400 number of rectangles, and this patch improved up abt 10 fps(sw), 20fps(gl). @TEST CODE MAX_SIZE = 400; for(int i=0; i< MAX_SIZE; i++) { Evas_Object *rect = evas_object_rectangle_add(layout); int x = rand() % WINDOW_WIDTH; int y = rand() % WINDOW_HEIGHT; evas_object_resize(rect, ELM_SCALE_SIZE(200), ELM_SCALE_SIZE(200)); evas_object_move(rect, x, y); evas_object_color_set(rect, (rand() % 256), (rand() % 256), (rand() % 256), 255); evas_object_show(rect); Elm_Transit *transit = elm_transit_add(); elm_transit_object_add(transit, rect); int dX = rand() % WINDOW_WIDTH; int dY = rand() % WINDOW_HEIGHT; elm_transit_effect_translation_add(transit, 0, 0, dX - x, dY - y); elm_transit_repeat_times_set(transit, -1); elm_transit_duration_set(transit, 1.0); elm_transit_go(transit); }
