Syntax

C++

public static int GetNearestBitsPerPixel( 
   PixelFormat pixelFormat 
)

Public Shared Function GetNearestBitsPerPixel( _ 
   ByVal pixelFormat As PixelFormat _ 
) As Integer

public: 
static int GetNearestBitsPerPixel(  
   PixelFormat pixelFormat 
)

Parameters

pixelFormat
The input pixel format.

Return Value

The nearest bits per pixel value supported by LEAD for the specified image pixel format.

Remarks

For more information refer to RasterImage and GDI/GDI+.
