Return Value

• in-process, unmanaged C++: Pointer to an array of doubles (see Remarks)

The return values are in an array of doubles:

[ Color, LineType, LineFont, LineWidth, LayerID, LayerOverride, StartPt[3], EndPt[3], FocusPt[3], ApexPt[3] ]

where:

Color = COLORREF returned as an integer. Return value could be 0 or -1 for default color.

LineType = line type. Valid returns as defined in swLineTypes_e. A LineType is a combination of a LineStyle and LineWeight.

LineFont = Value is used for polyline font information.

LineWidth = integer value defining the line width. Valid width values as defined in swLineWeights_e.

LayerID = integer value indicating which layer holds this entity. Obtain the ILayer object by passing this integer value to ILayerMgr::GetLayerById or ILayerMgr::IGetLayerById.

LayerOverride = integer with bit flags set to determine which properties, if any, have been overridden with respect to the Layer default properties. If the bit value is set, then the specific property or properties have been overridden. The bit indicators are: color = 0x1, style = 0x2, and width = 0x4. Therefore, if LayerOverride was returned as 3, you know the color and style have been specifically set for this item and may not match the default values associated with this item's layer.

StartPt[3] = array of 3 doubles (X,Y,Z) describing the parabola start point.

EndPt[3] = array of 3 doubles (X,Y,Z) describing the parabola end point.

FocusPt[3] = array of 3 doubles (X,Y,Z) describing the parabola focus point.

ApexPt[3] = array of 3 doubles (X,Y,Z) describing the parabola apex point.

This set of data repeats for each parabola in the view. The size of the array is (NumParabolas * 18).  To determine the number of parabolas, use IView::GetParabolaCount.
