Assembly:  MediaCy.IQL.Features (in MediaCy.IQL.Features.dll) Version: 10.0.6912.0
Syntax
VB
Copy
Sub GetEllipse ( 
	lIndex As Integer,
	<OutAttribute> ByRef Cx As Double,
	<OutAttribute> ByRef Cy As Double,
	<OutAttribute> ByRef MajAx As Double,
	<OutAttribute> ByRef MinAx As Double,
	<OutAttribute> ByRef MajAngle As Double
)

Parameters

lIndex
Type: SystemInt32
Index of subregion to report ellipse parameters for.
Cx
Type: SystemDouble
x-coordinate of the center of the ellipse
Cy
Type: SystemDouble
y-coordinate of the center of the ellipse
MajAx
Type: SystemDouble
length of the major axis (pixels)
MinAx
Type: SystemDouble
length of the minor axis (pixels)
MajAngle
Type: SystemDouble
orientation of the major axis in degrees counterclockwise from the horizontal. The value will be from zero to 360.
Remarks
The Type property for the lIndex feature must have the mcftEllipseAny bit set in its Type or an error will result. Note that features of Type mcftCircle may have nonzero MajAngle values: in this case, the angle specifies the angle at which any marking radial or diameter line is to be drawn on a linked McGraphObjCircle.
