  13. Description
  14. -----------
  15. Abstract base class for everything in 2D space. Canvas items are laid out in a tree; children inherit and extend their parent's transform. **CanvasItem** is extended by :ref:`Control<class_Control>` for GUI-related nodes, and by :ref:`Node2D<class_Node2D>` for 2D game objects.
  16. Any **CanvasItem** can draw. For this, :ref:`queue_redraw<class_CanvasItem_method_queue_redraw>` is called by the engine, then :ref:`NOTIFICATION_DRAW<class_CanvasItem_constant_NOTIFICATION_DRAW>` will be received on idle time to request a redraw. Because of this, canvas items don't need to be redrawn on every frame, improving the performance significantly. Several functions for drawing on the **CanvasItem** are provided (see ``draw_*`` functions). However, they can only be used inside :ref:`_draw<class_CanvasItem_private_method__draw>`, its corresponding :ref:`Object._notification<class_Object_private_method__notification>` or methods connected to the :ref:`draw<class_CanvasItem_signal_draw>` signal.
  17. Canvas items are drawn in tree order on their canvas layer. By default, children are on top of their parents, so a root **CanvasItem** will be drawn behind everything. This behavior can be changed on a per-item basis.
  18. A **CanvasItem** can be hidden, which will also hide its children. By adjusting various other properties of a **CanvasItem**, you can also modulate its color (via :ref:`modulate<class_CanvasItem_property_modulate>` or :ref:`self_modulate<class_CanvasItem_property_self_modulate>`), change its Z-index, blend mode, and more.
  19. Note that properties like transform, modulation, and visibility are only propagated to *direct* **CanvasItem** child nodes. If there is a non-**CanvasItem** node in between, like :ref:`Node<class_Node>` or :ref:`AnimationPlayer<class_AnimationPlayer>`, the **CanvasItem** nodes below will have an independent position and :ref:`modulate<class_CanvasItem_property_modulate>` chain. See also :ref:`top_level<class_CanvasItem_property_top_level>`.

This makes the texture look pixelated from up close, and smooth from a distance.
  236. Use this for non-pixel art textures that may be viewed at a low scale (e.g. due to :ref:`Camera2D<class_Camera2D>` zoom or sprite scaling), as mipmaps are important to smooth out pixels that are smaller than on-screen pixels.

This makes the texture look pixelated from up close, and smooth from a distance. Anisotropic filtering improves texture quality on surfaces that are almost in line with the camera, but is slightly slower. The anisotropic filtering level can be changed by adjusting :ref:`ProjectSettings.rendering/textures/default_filters/anisotropic_filtering_level<class_ProjectSettings_property_rendering/textures/default_filters/anisotropic_filtering_level>`.
  246. \ **Note:** This texture filter is rarely useful in 2D projects. :ref:`TEXTURE_FILTER_NEAREST_WITH_MIPMAPS<class_CanvasItem_constant_TEXTURE_FILTER_NEAREST_WITH_MIPMAPS>` is usually more appropriate in this case.

  500. Draws an unfilled arc between the given angles with a uniform ``color`` and ``width`` and optional antialiasing (supported only for positive ``width``). The larger the value of ``point_count``, the smoother the curve. See also :ref:`draw_circle<class_CanvasItem_method_draw_circle>`.
  501. If ``width`` is negative, it will be ignored and the arc will be drawn using :ref:`RenderingServer.PRIMITIVE_LINE_STRIP<class_RenderingServer_constant_PRIMITIVE_LINE_STRIP>`. This means that when the CanvasItem is scaled, the arc will remain thin. If this behavior is not desired, then pass a positive ``width`` like ``1.0``.
  502. The arc is drawn from ``start_angle`` towards the value of ``end_angle`` so in clockwise direction if ``start_angle < end_angle`` and counter-clockwise otherwise. Passing the same angles but in reversed order will produce the same arc. If absolute difference of ``start_angle`` and ``end_angle`` is greater than :ref:`@GDScript.TAU<class_@GDScript_constant_TAU>` radians, then a full circle arc is drawn (i.e. arc will not overlap itself).

  633. Draws interconnected line segments with a uniform ``width``, point-by-point coloring, and optional antialiasing (supported only for positive ``width``). Colors assigned to line points match by index between ``points`` and ``colors``, i.e. each line segment is filled with a gradient between the colors of the endpoints. When drawing large amounts of lines, this is faster than using individual :ref:`draw_line<class_CanvasItem_method_draw_line>` calls. To draw disconnected lines, use :ref:`draw_multiline_colors<class_CanvasItem_method_draw_multiline_colors>` instead. See also :ref:`draw_polygon<class_CanvasItem_method_draw_polygon>`.
  634. If ``width`` is negative, it will be ignored and the polyline will be drawn using :ref:`RenderingServer.PRIMITIVE_LINE_STRIP<class_RenderingServer_constant_PRIMITIVE_LINE_STRIP>`. This means that when the CanvasItem is scaled, the polyline will remain thin. If this behavior is not desired, then pass a positive ``width`` like ``1.0``.

  886. Show the **CanvasItem** if it's currently hidden. This is equivalent to setting :ref:`visible<class_CanvasItem_property_visible>` to ``true``. For controls that inherit :ref:`Popup<class_Popup>`, the correct way to make them visible is to call one of the multiple ``popup*()`` functions instead.
