   int rgb
)
'Declaration
 
Public Shared Function FromRgb( _
   ByVal rgb As Integer _
) As RasterColor
'Usage

Dim value As RasterColor
 
value = RasterColorHelper.FromRgb(rgb)
public static RasterColor FromRgb( 
   int rgb
)
 function Leadtools.RasterColorHelper.FromRgb( 
   rgb 
)
public:
static RasterColor FromRgb( 
   int rgb
) 

Parameters
