IsValidBitsPerPixel Method

Summary

Determines whether the specified bits per pixel value supported by LEADTOOLS is compatible with GDI+.

Syntax

C#
VB
C++
public static bool IsValidBitsPerPixel( 
   int bitsPerPixel 
) 
Public Shared Function IsValidBitsPerPixel( _ 
   ByVal bitsPerPixel As Integer _ 
) As Boolean 
public: 
static bool IsValidBitsPerPixel(  
   int bitsPerPixel 
)  

Parameters

bitsPerPixel
The input bits per pixel value.

Return Value

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

Remarks

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