public static class GdiExtensionMethods
The GdiExtensionMethods type exposes the following members.
Methods| Name | Description | |
|---|---|---|
 | Add | |
| AddScaled | |
| Center | Calculates the center of the provided rectangle. |
  | ClosedCardinalSplineToBezierSegments(PointF, Int32) | Converts a closed cardinal spline, given by the points in points, to Bezier segments. |
| ClosedCardinalSplineToBezierSegments(PointF, Int32, Single) | Converts a closed cardinal spline, given by the points in points, to Bezier segments. |
| DistanceSquaredTo | |
| DistanceTo | |
| DotProduct | |
| ExpandToInclude | Expands the rectangle r, so that is contains the point p. |
| FlattenBezierSegment | Flattens a bezier segment, using only an absolute tolerance. The flattened points are stored together with their curve parameter t. |
| FlipSign | |
| FlipXY | |
| GetFractionalIndexFromDistanceFromEndOfBezierCurve | |
| GetFractionalIndexFromDistanceFromEndOfPartialPolylineCurve | Gets the fractional index into points of a partial polyline by searching a point along the partial polyline that has a specified distance to the end point of the partial polyline. |
| GetFractionalIndexFromDistanceFromEndOfPolylineCurve | Gets the fractional index into points of a polyline by searching a point along the polyline that has a specified distance to the end point of the polyline. |
| GetFractionalIndexFromDistanceFromStartOfBezierCurve | |
| GetFractionalIndexFromDistanceFromStartOfPartialPolylineCurve | Gets the fractional index into points of a partial polyline by searching a point along the partial polyline that has a specified distance to the start point of the partial polyline. |
| GetFractionalIndexFromDistanceFromStartOfPolylineCurve | Gets the fractional index into points of a polyline by searching a point along the polyline that has a specified distance to the start point of the polyline. |
| GetParameterOnLineSegmentFromDistanceToPoint | If a line segment is given by this parametric equation: p(t)=(1-t)*p0 + t*p1, this function calculates the parameter t at which the point p(t) has a squared distance dsqr from the pivot point pivot. The argument chooseFarSolution determines which of two possible solutions is choosen. |
| Half | Calculates the half of the original size. |
| Interpolate | Interpolates between the points p0 and p1. |
| IsPointIntoDistance(PointF, Double, IEnumerablePointF) | Determines whether or not a given point is into a certain distance of a polyline. |
| IsPointIntoDistance(PointF, Double, PointF, PointF) | Determines whether or not a given point (point) is into a distance to a finite line, that is spanned between two points lineOrg and lineEnd. |
| LengthBetween | |
| Normalize | |
| OpenCardinalSplineToBezierSegments(PointF, Int32) | Converts an open cardinal spline, given by the points in points, to Bezier segments. |
| OpenCardinalSplineToBezierSegments(PointF, Int32, Single) | Converts an open cardinal spline, given by the points in points, to Bezier segments. |
| Rotate90Degree | |
| Scale(PointF, Double) | Multiply a PointF structure with a factor. |
| Scale(RectangleF, Double) | Multiply a RectangleF structure with a factor. |
| Scale(SizeF, Double) | Multiply a size structure with a factor. |
| ShortenBezierCurve | |
| ShortenBezierSegment | Shortens a Bezier segment and returns the Bezier points of the shortened segment. |
| ShortenedBy(PointF, RADouble, RADouble) | Returns a new, shortened polyline. If the shortened line would have zero or negative length, null is returned. |
| ShortenedBy(PointF, Int32, Int32, RADouble, RADouble) | Returns a new, shortened polyline. If the shortened line would have zero or negative length, null is returned. |
| ShortenLineSegment | Shortens a line segment and returns the line points of the shortened segment. |
| ShortenPartialPolylineByDistanceFromStartAndEnd | Shortens a partial polyline, given by the first point at index startIndex and the last index endIndex, at both sides in such a way that the new start has a distance distanceFromStart to the original start of the polyline, and the new end has a distance distanceFromEnd to the original end of the polyline. If the shortening leads to a polyline of zero length, then null is returned. |
| ShortenPolylineByDistanceFromStartAndEnd | Shortens a polyline at both sides in such a way that the new start has a distance distanceFromStart to the original start of the polyline, and the new end has a distance distanceFromEnd to the original end of the polyline. If the shortening leads to a polyline of zero length, then null is returned. |
| SquareDistanceLineToPoint | Calculates the squared distance between a finite line and a point. |
| Subtract | |
| ToAltaxo | |
| ToGdi | |
| TotalLineLength(PointF) | Calculates the total length of a polyline. |
| TotalLineLength(PointF, Int32, Int32) | Calculates the total length of a polyline. |
| VectorLength | |
| VectorLengthSquared |
