SyntaxC#
public class EllipseToMetafileCommand : BaseMetafileCommand
The EllipseToMetafileCommand type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | EllipseToMetafileCommand | Initializes a new instance of the EllipseToMetafileCommand class |
Properties| Name | Description | |
|---|---|---|
 | AxesRatio | The ratio of the minor axis to the major axis. |
| CenterPoint | The center point of the ellipse. |
| IsGeometric |
Returns true if the command describes a path (either with jumps or marks). LaserOn commands (aka drills) are excluded.
(Inherited from BaseMetafileCommand) |
| IsHelix | Creates a helix if z coordinates of start and center are different. CenterPoint.z will be used as z for the end of the helix. |
| Item |
Returns CenterPoint (Overrides BaseMetafileCommandItemInt32) |
| Label |
The display name of the meta file command type.
(Overrides BaseMetafileCommandLabel) |
| Length |
Length of the vector.
Is simplified as length of an arc.
(Overrides BaseMetafileCommandLength) |
 | MetafileCommandFactory | (Inherited from BaseMetafileCommand) |
| OrientationAngle | The orientation of the ellipse, in radians. Positive value means a counterclockwise direction. |
| PointCount |
The number of points accessible by the indexer.
(Overrides BaseMetafileCommandPointCount) |
| SegmentEndPointPair |
The end points of the segment generated by this metafile command. This value functions as a cache to reduce redundant calculations.
(Inherited from BaseMetafileCommand) |
| SweepAngle | The sweep angle of the ellipse, in radians. Positive value means a counterclockwise direction. This angle is the angle used in the parametric equation representations of the ellipse. |
Methods| Name | Description | |
|---|---|---|
| CalculatePerimeter | |
| CompareWith | (Inherited from BaseMetafileCommand) |
| CopyFrom |
Copies the property values from a given metafile command. The InvokeCommandChanged is invoked at the end.
(Inherited from BaseMetafileCommand) |
| CreateArc |
Creates an arc from the ellipse.
(Overrides BaseMetafileCommandCreateArc(Int32, Int32, Double)) |
| CreateCubicCurves |
Calculates a set of cubic curves which are able to approximately
replace the arc.
(Overrides BaseMetafileCommandCreateCubicCurves) |
| CreateEllipse |
Tries to approximate the command by an elliptical arc. Available
only for arcs yet, creating an ellipse with both semi axes having
the length of the arc's radius.
Return ValueThe calculated elliptical arc.(Inherited from BaseMetafileCommand) |
| CreatePolyline |
Creates a polyline from the command. The creation process is done
in two steps: In the first step a polyline with numOfPoints
points is created; this number should not be too small to have a
good approximation guaranteed. In the second step all straight
points are removed using the delta parameter.
See CheckThreePointsOnLinearityWithDistance(dvec3, dvec3, dvec3, Double)
for details.
(Overrides BaseMetafileCommandCreatePolyline(Int32, Double)) |
| CreateQuadraticCurves |
Calculates a set of quadratic curves which are able to approximately
replace the arc.
(Overrides BaseMetafileCommandCreateQuadraticCurves) |
 | DoCompareWith | (Inherited from BaseMetafileCommand) |
| DoCopyFrom |
Copies extra property values from a given metafile command. This method is called from CopyFrom(BaseMetafileCommand).
(Overrides BaseMetafileCommandDoCopyFrom(BaseMetafileCommand)) |
| DoInvert | (Overrides BaseMetafileCommandDoInvert) |
| DoInvokeCommandChanged | (Inherited from BaseMetafileCommand) |
| DoSplitByLength | (Overrides BaseMetafileCommandDoSplitByLength(Double, dmat4)) |
| DoTransform | (Overrides BaseMetafileCommandDoTransform(dmat4)) |
| DoUpdateEndPoint | (Overrides BaseMetafileCommandDoUpdateEndPoint(dvec3)) |
| GenerateCommandPoints |
Generates a list of points that are significant to the shape.
(Overrides BaseMetafileCommandGenerateCommandPoints) |
| GetTransformedLength |
Returns the length of the transformed vector.
(Overrides BaseMetafileCommandGetTransformedLength(dmat4)) |
| InvokeCommandChanged | (Inherited from BaseMetafileCommand) |
| IsEqual |
Checks if two objects of type BaseMetafileCommand (or a derived class)
are equal to each other. All position values must differ less than delta
d to be considered as equal.
Angles, axes ratios and the check on collinearity of lines are using
the fixed value 0.01 rad.
(Overrides BaseMetafileCommandIsEqual(Object, Double)) |
| SetZCoordsToZero |
Sets all z-coordinates in this object to zero.
(Overrides BaseMetafileCommandSetZCoordsToZero) |
| ShowUI(String) | (Inherited from BaseMetafileCommand) |
| ShowUI(String, PropertyMask) | (Overrides BaseMetafileCommandShowUI(String, PropertyMask)) |
| ShowUICallback | (Overrides BaseMetafileCommandShowUICallback(BaseMetafileCommandView)) |
| SplitByLength |
Splits the command at the provided length.
(Inherited from BaseMetafileCommand) |
| SplitIntoTwo |
Creates two adjacent commands of the same type at the same position
in a way that the two commands can replace the original.
(Inherited from BaseMetafileCommand) |
| ToString | Returns a string that represents the current object. (Overrides ObjectToString) |
| UpdateEndPoint |
Updates the start and end points of this command based on a given starting point.
(Inherited from BaseMetafileCommand) |
Events| Name | Description | |
|---|---|---|
 | CommandChanged |
Raised whenever a metafile command is changed.
(Inherited from BaseMetafileCommand) |
