'Declaration
 
Public Overloads Function AddMark( _
   ByVal mark As ImGearARTMark, _
   ByVal type As ImGearARTCoordinatesType, _
   ByVal groupName As String _
) As Integer

'Usage
 
Dim instance As ImGearARTPage
Dim mark As ImGearARTMark
Dim type As ImGearARTCoordinatesType
Dim groupName As String
Dim value As Integer
 
value = instance.AddMark(mark, type, groupName)

public int AddMark( 
   ImGearARTMark mark,
   ImGearARTCoordinatesType type,
   string groupName
)

public: int AddMark( 
   ImGearARTMark* mark,
   ImGearARTCoordinatesType type,
   string* groupName
)

public:
int AddMark( 
   ImGearARTMark^ mark,
   ImGearARTCoordinatesType type,
   String^ groupName
)

Parameters

mark: Reference to the mark to add.
type: Type of the coordinate system the mark coordinates are specified in.
groupName: Name of the group to add the mark to.

Return Value

Integer value.

You must specify the type of the mark's coordinate system. The mark will be drawn according to the type of its coordinate system.

Please make sure the mark does not have parent group (i.e. ImGearARTMark.ParentGroup is null), otherwise ImageGear.Core.ImGearException will be thrown. If the mark to be added already has parent group, please clone it prior to adding to the page.
