Use "lv_animimg" , can't stop the animation at last picture

//Write codes screen_3
ui->screen_3 = lv_obj_create(NULL);

//Write style state: LV_STATE_DEFAULT for style_screen_3_main_main_default
static lv_style_t style_screen_3_main_main_default;
if (style_screen_3_main_main_default.prop_cnt > 1)
	lv_style_reset(&style_screen_3_main_main_default);
else
	lv_style_init(&style_screen_3_main_main_default);
lv_style_set_bg_color(&style_screen_3_main_main_default, lv_color_make(0xff, 0xff, 0xff));
lv_style_set_bg_opa(&style_screen_3_main_main_default, 0);
lv_obj_add_style(ui->screen_3, &style_screen_3_main_main_default,

LV_PART_MAIN|LV_STATE_DEFAULT);

//Write codes screen_3_animimg_1
ui->screen_3_animimg_1 = lv_animimg_create(ui->screen_3);
lv_obj_set_pos(ui->screen_3_animimg_1, 0, 0);
lv_obj_set_size(ui->screen_3_animimg_1, 480, 272);	
    lv_animimg_set_src(ui->screen_3_animimg_1, (lv_img_dsc_t**) screen_3_animimg_1_imgs, 121);
lv_animimg_set_duration(ui->screen_3_animimg_1, 4033);
lv_animimg_set_repeat_count(ui->screen_3_animimg_1, 0);
lv_animimg_start(ui->screen_3_animimg_1);



 Every time , the animation stop at the first picture of " screen_3_animimg_1_imgs " , but i want to stop at the last picture . How to do ?
