Detailed Description

This class represents a path which contains one or more figures.

Member Function Documentation

◆ AppendEllipse()

Path.AppendEllipse ( rect )

Add an ellipse figure to the end of current path.

Parameters

[in] rect The enclosing rectangle of an ellipse figure.

Returns: true means success, while false means failure.

◆ AppendRect()

Path.AppendRect ( rect )

Add a rectangle figure to the end of current path.

Parameters

[in] rect A rectangle which specifies a rectangle figure.

Returns: true means success, while false means failure.

◆ Clear()

Path.Clear ( )

Clear all points.

Returns: None.

◆ CloseFigure()

Path.CloseFigure ( )

Close current figure (which is also the last figure in current path).

When closing current figure, the last point's type may be changed:

If the last point's type is Path.e_TypeMoveTo, that means the last figure just has one point and cannot be closed and current function will return false.
If the last point's type is Path.e_TypeLineTo, the type will be changed to Path.e_TypeLineToCloseFigure.
If the last point's type is Path.e_TypeLineTo, the type will be changed to Path.e_TypeBezierToCloseFigure.
If the last point's type is already Path.e_TypeLineToCloseFigure or Path.e_TypeBezierToCloseFigure, that means the last figure has been closed. The type will not be changed and function will still return true.

Returns: true means success, while false means failure.

◆ CubicBezierTo()

Path.CubicBezierTo	(	point1	,
		point2	,
		point3
	)

Add a cubic bezier spline to the end of current figure, by three points: two control points and one target point.

If this function succeeds, parameter point3 will become the new "current point".

Parameters

[in]	point1	New point as the first control point for cubic bezier, in PDF coordinate system.
[in]	point2	New point as the second control point for cubic bezier, in PDF coordinate system.
[in]	point3	New point as target point for cubic bezier, in PDF coordinate system.

Returns: true means success, while false means failure.

◆ GetPoint()

Path.GetPoint ( index )

Get a point specified by index.

Parameters

[in] index The index of the point. Valid range: 0 to (count-1). count is returned by function Path.GetPointCount.

Returns: The specified point.

◆ GetPointCount()

Path.GetPointCount ( )

Get the count of points.

Returns: The count of points.

◆ GetPointType()

Path.GetPointType ( index )

Get the type of a point specified by index.

Parameters

[in] index The index of the point. Valid range: 0 to (count-1). count is returned by function Path.GetPointCount.

Returns: The type of specified point. Please refer to values starting from Path.e_TypeMoveTo and this would be one of these values.

◆ IncreasePointCount()

Path.IncreasePointCount ( count )

Increase the point count and prepare adequate memory for these new points.

This function will allocate more memory for given point count and initialize these new points with point (0, 0) and type Path.e_TypeMoveTo by default. After calling this function successfully, user can use function Path.SetPoint to set these new points.

Parameters

[in] count The new point count. It should not be negative.

Returns: None.

◆ IsEmpty()

Path.IsEmpty ( )

Check whether current object is empty or not.

When the current object is empty, that means current object is useless.

Returns: true means current object is empty, while false means not.

◆ LineTo()

Path.LineTo ( point )

Add a point to the end of current figure, and a line is to be drawn from current point to the new point.

If this function succeeds, the new point will become the new "current point".

Parameters

[in] point New point, in PDF coordinate system.

Returns: true means success, while false means failure.

◆ MoveTo()

Path.MoveTo ( point )

Add a point to the end of current path, to start a new figure.

If this function succeeds, the new point will become the new "current point", and the new figure will become the new "current figure".

Parameters

[in] point New point, in PDF coordinate system.

Returns: true means success, while false means failure.

◆ RemovePoint()

Path.RemovePoint ( index )

Remove a point specified by index.

Parameters

[in] index The index of the point to be removed. Valid range: 0 to (count-1). count is returned by function Path.GetPointCount.

Returns: true means success, while false means failure.

◆ SetPoint()

Path.SetPoint	(	index	,
		point	,
		type
	)

Change the value and type of a point specified by index.

Parameters

[in]	index	The index of the point. Valid range: 0 to (count-1). count is returned by function Path.GetPointCount.
[in]	point	The new point to set, in PDF coordinate system.
[in]	type	The type used to set to the new point. Please refer to values starting from Path.e_TypeMoveTo and this should be one of these values.

Returns: true means success, while false means failure.

◆ Transform()

Path.Transform ( matrix )

Transform all points in current path with a given matrix.

Parameters

[in] matrix A matrix used for transforming.

Returns: None.

◆ e_TypeMoveTo

Path.e_TypeMoveTo

static

Enumeration for point type in path.

Values of this enumeration should be used alone.

Indicates that the point is the first point of a figure.
