SetCartographicWithOptionalParametersAndRenderPass Method (IAgStkGraphicsTextBatchPrimitive)
See Also  Example
CentralBody
The central body the positions are defined on.
Positions
An array containing the new positions for each string in the text batch, provided in the order latitude, longitude, altitude.
Text
The text for strings in the text batch. Each element in this collection corresponds to a set of latitude, longitude, and altitude elements in positions.
OptionalParameters
Optional per-batch parameters or per-string parameters corresponding to positions. Each per-string parameter must have the same number of elements as positions.
RenderPassHint
An optimization hint indicating the Render Pass implied by per-strings colors defined in optionalParameters.





Description

For convenience. Defines the positions, text, and optional parameters of strings in a text batch using Cartographic positions. Longitude and latitude are in radians, and altitude is in meters. This is equivalent to converting each position in positions to Cartesian and calling Set.

Syntax

[Visual Basic .NET] 
Public Sub SetCartographicWithOptionalParametersAndRenderPass( _
   ByVal CentralBody As String, _
   ByRef Positions As System.Array, _
   ByRef Text As System.Array, _
   ByVal OptionalParameters As IAgStkGraphicsTextBatchPrimitiveOptionalParameters, _
   ByVal RenderPassHint As AgEStkGraphicsRenderPassHint _
)
[C#] 
public void SetCartographicWithOptionalParametersAndRenderPass(

   string CentralBody, 

   ref System.Array Positions, 

   ref System.Array Text, 

   IAgStkGraphicsTextBatchPrimitiveOptionalParameters OptionalParameters, 

   AgEStkGraphicsRenderPassHint RenderPassHint

);
[Managed C++] 
public: void SetCartographicWithOptionalParametersAndRenderPass(

   String __gc ^ CentralBody, 

   System::Array ^^ Positions, 

   System::Array ^^ Text, 

   IAgStkGraphicsTextBatchPrimitiveOptionalParameters ^ OptionalParameters, 

   AgEStkGraphicsRenderPassHint RenderPassHint

);
[Java] 
public  setCartographicWithOptionalParametersAndRenderPass(

   String CentralBody, 

   Object[] Positions, 

   Object[] Text, 

   IAgStkGraphicsTextBatchPrimitiveOptionalParameters OptionalParameters, 

   AgEStkGraphicsRenderPassHint RenderPassHint

);
[Unmanaged C++] 
public: HRESULT SetCartographicWithOptionalParametersAndRenderPass(

   BSTR CentralBody, 

   SAFEARRAY ** Positions, 

   SAFEARRAY ** Text, 

   IAgStkGraphicsTextBatchPrimitiveOptionalParameters * OptionalParameters, 

   AgEStkGraphicsRenderPassHint RenderPassHint

);

Parameters

CentralBody
The central body the positions are defined on.
Positions
An array containing the new positions for each string in the text batch, provided in the order latitude, longitude, altitude.
Text
The text for strings in the text batch. Each element in this collection corresponds to a set of latitude, longitude, and altitude elements in positions.
OptionalParameters
Optional per-batch parameters or per-string parameters corresponding to positions. Each per-string parameter must have the same number of elements as positions.
RenderPassHint
Member Value Description
eStkGraphicsRenderPassHintOpaque 0 The collection of Color contains only opaque colors. This implies that each color's alpha component is 255.
eStkGraphicsRenderPassHintTranslucent 1 The collection of Color contains translucent colors. This implies that at least one color has an alpha component that is not 255.
eStkGraphicsRenderPassHintUnknown 2 It is unknown if the collection of Color contains opaque or translucent colors.
An optimization hint indicating the Render Pass implied by per-strings colors defined in optionalParameters.

Remarks

See Set for a full discussion.
