[Bug]label无法叠加在scope上

[dynofifa]

无法叠加在scope上
代码如下

  sgl_obj_t* scope = sgl_scope_create(NULL);
  sgl_obj_set_pos(scope, 0, 0);
  sgl_obj_set_size(scope, 160, 80);
  sgl_scope_set_bg_color(scope, sgl_rgb(0x00, 0x00, 0x00));
  sgl_scope_set_waveform_color(scope, sgl_rgb(0x00, 0xFF, 0x00));
  sgl_scope_set_grid_color(scope, sgl_rgb(0x32, 0x32, 0x32));
  sgl_scope_set_line_width(scope, 2);
  sgl_scope_set_alpha(scope, 255);
  sgl_scope_set_grid_line(scope, 1);
  sgl_scope_enable_auto_scale(scope, true);
  sgl_scope_set_max_display_points(scope, 160);
  sgl_scope_set_range(scope, 0, 1600);
  sgl_scope_set_y_label_font(scope, &consolas14);
  sgl_scope_show_y_labels(scope, true);
  sgl_scope_set_data_buffer(scope, scope_buffer, 160);


  sgl_obj_t *label = sgl_label_create(NULL);
  sgl_obj_set_pos(label , 0, 0);
  sgl_obj_set_size(label , 80, 50);
  sgl_label_set_font(label , &consolas14);
  sgl_label_set_text(label , "label test");

  sgl_obj_move_top(fanspeed_label);

这个没有问题，字体默认颜色是黑色，因为scope默认是背景是黑色，所有很难发现label，你需要设置下label的为白色即可（sgl_label_set_text_color(label , SGL_COLOR_WHITE);
）：下面是测试代码
sgl_obj_t* scope = sgl_scope_create(NULL);
sgl_obj_set_pos(scope, 0, 0);
sgl_obj_set_size(scope, 160, 80);
sgl_scope_set_bg_color(scope, sgl_rgb(0x00, 0x00, 0x00));
sgl_scope_set_waveform_color(scope, sgl_rgb(0x00, 0xFF, 0x00));
sgl_scope_set_grid_color(scope, sgl_rgb(0x32, 0x32, 0x32));
sgl_scope_set_line_width(scope, 2);
sgl_scope_set_alpha(scope, 255);
sgl_scope_set_grid_line(scope, 1);
sgl_scope_enable_auto_scale(scope, true);
sgl_scope_set_max_display_points(scope, 160);
sgl_scope_set_range(scope, 0, 1600);
sgl_scope_set_y_label_font(scope, &consolas14);
sgl_scope_show_y_labels(scope, true);
sgl_scope_set_data_buffer(scope, scope_buffer, 160);

sgl_obj_t *label = sgl_label_create(NULL);
sgl_obj_set_pos(label , 0, 0);
sgl_obj_set_size(label , 80, 50);
sgl_label_set_font(label , &consolas14);
sgl_label_set_text(label , "label test");
sgl_label_set_text_color(label , SGL_COLOR_WHITE);

sgl_obj_move_top(label);
