例如，要获取单行 Label 所显示的字符串大小，请使用：

var string_size = $Label.get_theme_font("font").get_string_size($Label.text, HORIZONTAL_ALIGNMENT_LEFT, -1, $Label.get_theme_font_size("font_size"))

Label label = GetNode<Label>("Label");
Vector2 stringSize = label.GetThemeFont("font").GetStringSize(label.Text, HorizontalAlignment.Left, -1, label.GetThemeFontSize("font_size"));
\ **注意：**\ 由于 :ref:`get_string_size()<class_Font_method_get_string_size>` 考虑了字距调整、提前量和子像素定位，因此对字符串的子字符串使用单独的 :ref:`get_string_size()<class_Font_method_get_string_size>` 调用，然后将结果加在一起，将返回与对完整字符串使用单个 :ref:`get_string_size()<class_Font_method_get_string_size>` 调用的返回值不同的结果 。

字体变体能够沿着某个给定的设计轴对字形的特性进行连续的变化，例如字重、宽度、斜度。

var variation_list = fv.get_supported_variation_list()
for tag in variation_list:
var name = TextServerManager.get_primary_interface().tag_to_name(tag)
