Description
When I draw round-ending lines by lv_line’s obj, it can be rounded well.
However, when I draw round-ending lines on lv_canvas’ obj, it can’t display rounded lines.
How to fix it?
What MCU/Processor/Board and compiler are you using?
ESP32
What do you want to achieve?
Round-ending lines can be shown correctly on a canvas.
What have you tried so far?
Code to reproduce
static lv_point_t points[] = { {10,10}, {200,100}, {100,220} };
static lv_style_t line_style;
lv_style_copy(&line_style, &lv_style_plain);
line_style.line.width = 10;
line_style.line.rounded = true; // set round-ending
line_style.line.color = LV_COLOR_BLUE;
lv_color_t *cbuf = (lv_color_t*) lv_mem_alloc( LV_CANVAS_BUF_SIZE_TRUE_COLOR(240,240));
lv_obj_t* canvas = lv_canvas_create(lv_scr_act(),NULL);
lv_canvas_set_buffer(canvas, cbuf, 240, 240, LV_IMG_CF_TRUE_COLOR);
lv_canvas_fill_bg(canvas, LV_COLOR_BLACK);
lv_canvas_draw_line(canvas, points, 3, &line_style);
