Detailed Description
This is a specialized interface for a 2D poly-polygon containing straight line and Bezier segments.
This poly-polygon can contain polygons consisting of a mixture of cubic Bezier curves and straight lines. As the straight line is a special case of a cubic Bezier curve (control points collinear with the line through start and end point), this can be expressed uniformly with a sequence of RealBezierSegment2Ds.
By convention, a RealBezierSegment2D is a straight line segment, if all three contained points are strictly equal.

◆ getBezierSegment()
| ::com::sun::star::geometry::RealBezierSegment2D getBezierSegment | ( | [in] long | nPolygonIndex, |
| [in] long | nPointIndex | ||
| ) | |||
| raises | ( | com::sun::star::lang::IndexOutOfBoundsException | |
| ) | |||
Get a single point from the poly-polygon.
- Parameters
-
nPolygonIndex The index of the polygon where the point to be extract is contained within. This index must be in the range [0,numPolygons-1]. nPointIndex The index of the point in the polygon specified by nPolygonIndex, which is to be retrieved. This value must not exceed the number of points in this polygon minus one.
- Returns
- the requested point.
- Exceptions
-
com::sun::star::lang::IndexOutOfBoundsException if one of the given values exceed the permissible range.
◆ getBezierSegments()
| sequence< sequence < ::com::sun::star::geometry::RealBezierSegment2D > > getBezierSegments | ( | [in] long | nPolygonIndex, |

Query subset of this poly-polygon.
Query subset of this poly-polygon, starting at the given polygon and the given point within that polygon, and containing the specified number of polygons and points in the last polygon.
- Parameters
-
nPolygonIndex The index of the polygon to start point retrieval with. This index must be in the range [0,numPolygons-1]. nNumberOfPolygons The number of polygons to extract. This value must not exceed numPolygons-nPolygonIndex. nPointIndex The index of the first point in the first polygon to extract. This value must not exceed the number of points in this polygon minus one. nNumberOfPoints The number of points to extract from the last polygon. This value must not exceed the number of points in this last polygon minus one.
- Returns
- the sequence of extracted points.
- Exceptions
-
com::sun::star::lang::IndexOutOfBoundsException if one of the given values exceed the permissible range.
◆ setBezierSegment()
| void setBezierSegment | ( | [in] ::com::sun::star::geometry::RealBezierSegment2D | point, |
| [in] long | nPolygonIndex, | ||
| [in] long | nPointIndex | ||
| ) | |||
| raises | ( | com::sun::star::lang::IndexOutOfBoundsException | |
| ) | |||
Set a single point on the poly-polygon.
The remaining points of the poly-polygon will not be changed by this method. Use XBezierPolyPolygon2D::getNumberOfPolygons() or XBezierPolyPolygon2D::getNumberOfPolygonPoints() to append points or polygons, respectively.
- Parameters
-
point The point to be set at the poly-polygon. nPolygonIndex The index of the polygon to insert the point in. This index must be in the range [0,numPolygons]. nPointIndex The index of the point in the polygon specified by nPolygonIndex, which is to be set. This value must not exceed the number of points in this polygon.
- Exceptions
-
com::sun::star::lang::IndexOutOfBoundsException if one of the given values exceed the permissible range.
◆ setBezierSegments()
| void setBezierSegments | ( | [in] sequence< sequence< ::com::sun::star::geometry::RealBezierSegment2D > > | points, |
| [in] long | nPolygonIndex | ||
| ) | |||
| raises | ( | com::sun::star::lang::IndexOutOfBoundsException | |
| ) | |||
Set the specified sequence of Bezier segments to the poly-polygon.
This method can either set the whole poly-polygon to the new data, or insert the segments at the given index
- Parameters
-
points the points. nPolygonIndex The index of the polygon to start segment insertion with. This index must be in the range [0,numPolygons], and the insertion will take place before this position (i.e. when specifying 0 here, the given Bezier sequence will precede all existing polygons already within the poly-polygon). To append to a poly-polygon, call setPoints() with XBezierPolyPolygon2D::getNumberOfPolygons() as the polygon index. If nPolygonIndex is -1, the given Bezier sequence replaces the poly-polygon content, such that after this method completes, it contains exactly the specified Bezier segment data.
- Exceptions
-
com::sun::star::lang::IndexOutOfBoundsException if one of the given values exceed the permissible range.
