## Detailed Description

An ink annotation represents a freehand "scribble" composed of one or more disjoint paths.
Ink annotation is a kind of markup annotation, so class Ink is derived from class Markup, offers functions to get/set ink annotation's properties and also and reset appearance stream of an ink annotation.
For an ink annotation, ink list property is required. So please ensure that an ink annotation has valid ink list property before resetting its appearance stream; otherwise the ink annotation cannot be reset appearance stream.

Note
  For a newly created ink annotation, if user calls function Annot.ResetAppearanceStream (inherited from Ink's parent class) directly after setting required ink list property and not setting any other properties, the default appearance will be used:
  border width = 2.0, border style = BorderInfo.e_Solid, border color = 0xFFFF0000 (red), opacity = 1.0.

## Member Function Documentation

## ◆ constructor()

Ink.constructor | ( | annot |  | ) |

Constructor, with parent class object.

Parameters

  [in] | annot | Parent class object.

## ◆ EnableUseBezier()

Ink.EnableUseBezier | ( | use_bezier |  | ) |

Enable to use bezier spline to generate ink path for ink annotation's appearance.

If this function is not called, Foxit PDF SDK will use bezier spline to generate ink path by default.

Parameters

  [in] | use_bezier | A boolean to decide whether to use bezier spline or not: true means to use bezier spline to generate ink path, while false means to use straight line to connect adjacent points to generate ink path.

Returns
  None.

## ◆ GetInkList()

Ink.GetInkList | ( |  | ) |

Get ink list data.

Ink list property is required for an ink annotation and this property has effect on ink annotation's appearance. The ink list contains one or more stroked path.
In Foxit PDF SDK, class Path is used to represent the ink list data, but the point types for path object have been specially simplified for ink list. Only Path.e_TypeMoveTo and Path.e_TypeLineTo types are used for points in the ink list:

- a point with type Path.e_TypeMoveTo means that this point is the start point of a stroked path. Usually the first in path object should be this type.
- a point with type Path.e_TypeLineTo means that this point is in a stroked path, which is started by a point with type Path.e_TypeMoveTo, and when function Annot.ResetAppearanceStream (inherited from Ink's parent class) is called, Foxit PDF SDK will connect this point with other points by curves.

Operations such as move the ink annotation, or set a new ink path to this annotation will update the ink path data, so that the previous returned path object would become invalid. In this case, user should call this function again to obtain the new path object.

Returns
  The ink list data. If the return value of function Path.IsEmpty for the returned path object is true, that means no ink list data can be found.

## ◆ SetInkList()

Ink.SetInkList | ( | ink_list |  | ) |

Set ink list data.

Ink list property is required for an ink annotation and this property has effect on ink annotation's appearance. The ink list contains one or more stroked path.
In Foxit PDF SDK, class Path is used to represent the ink list data, but the point types for path object have been specially simplified for ink list. Only Path.e_TypeMoveTo and Path.e_TypeLineTo types are used for points in the ink list:

- a point with type Path.e_TypeMoveTo means that this point is the start point of a stroked path. Usually the first in path object should be this type.
- a point with type Path.e_TypeLineTo means that this point is in a stroked path, which is started by a point with with type Path.e_TypeMoveTo, and when function Annot.ResetAppearanceStream (inherited from Ink's parent class) is called, Foxit PDF SDK will connect this point with other points by curves.

Specially, if input parameter ink_list contains bezier points (for example, added by function Path.CubicBezierTo), the control points will be ignored and only the target point will be used in the ink list data.
User is strongly recommended to pass a valid path object only with point types Path.e_TypeMoveTo and Path.e_TypeLineTo.
If user wants the effect to be shown in annotation's appearance, please call function Annot.ResetAppearanceStream after this function.

Parameters

  [in] | ink_list | New path object which specifies the new list data.

Returns
  None.
