Sets a coloring scheme to be associated with an image layer. The coloring scheme is for reference purposes only
and has no effect the coloring or display of the image.

VB.NET Usage

Function SetImageLayerColorScheme(LayerHandle As Integer, ColorScheme As Object) As Boolean
            Parameters

Sample Code

    Private Sub ImageLayerColoringScheme()
        Dim hndl As Integer
        Dim scheme As New MapWinGIS.GridColorScheme()
        Dim break As New MapWinGIS.GridColorBreak()
        'Create color break
        break.Caption = "forest"
        break.HighColor = System.Convert.ToUInt32(RGB(0, 255, 0))
        break.LowColor = System.Convert.ToUInt32(RGB(0, 255, 0))
        break.LowValue = 0
        break.HighValue = 0
        'Add color break to coloring scheme
        scheme.InsertBreak(break)
        'Get handle for layer 0
        hndl = Map1.get_LayerHandle(0)
        'set the coloring scheme for this layer
        Map1.SetImageLayerColorScheme(hndl, scheme)
    End Sub
