Leadtools Namespace > RasterImage Class : IsValidBitsPerPixelGdiPlus Method



bitsPerPixel
The input bits per pixel value.
Determines whether or not the specified bits per pixel value supported by LEAD is compatible with GDI+.

Syntax

Visual Basic (Declaration) 
Public Shared Function IsValidBitsPerPixelGdiPlus( _
   ByVal bitsPerPixel As Integer _
) As Boolean
Visual Basic (Usage)Copy Code
Dim bitsPerPixel As Integer
Dim value As Boolean
 
value = RasterImage.IsValidBitsPerPixelGdiPlus(bitsPerPixel)
C# 
public static bool IsValidBitsPerPixelGdiPlus( 
   int bitsPerPixel
)
C++/CLI 
public:
static bool IsValidBitsPerPixelGdiPlus( 
   int bitsPerPixel
)

Parameters

bitsPerPixel
The input bits per pixel value.

Return Value

true if bitsPerPixel is compatible with GDI+, otherwise it is false.
