FromDib(IBuffer,Int32) Method

Summary

Creates a new image from the specified Windows device independent bitmap (DIB) stored in a managed array.

Syntax

WinRT C#

C++

public static Leadtools.RasterImage FromDib(  
   IBuffer hdib, 
   int offset 
)

Public Overloads Shared Function FromDib( _ 
   ByVal hdib As IBuffer, _ 
   ByVal offset As Integer _ 
) As Leadtools.RasterImage

public static Leadtools.RasterImage FromDib(  
   IBuffer hdib, 
   int offset 
)

 function Leadtools.RasterImage.FromDib(IBuffer,Int32)(  
   hdib , 
   offset  
)

public: 
static Leadtools.RasterImage^ FromDib(  
   IBuffer^ hdib, 
   int offset 
)

Parameters

hdib
Data containing the Windows DIB.

offset
Byte offset into hdib where the data starts.

Return Value

The newly created RasterImage object.

Remarks

When this method is completed, there are two copies of the image in memory: the original DIB and the RasterImage it creates. Freeing one will not affect the other.

This method supports the standard DIB formats (BI_RGB and BI_BITFIELDS) as well as some FOURCC (Four Character Code) formats that some capture cards output.

These are the FOURCC that LEADTOOLS supports at the moment:

YVU9 (YUV9), I420 (YUV12), YUV2 , YV12 , IF09 , IYUV , UYVY , cyuv, YUY2, YVYU, Y41P, Y211, Y41T, Y42T.

This method does not support signed images.
