ToDibArray Method

Gets a managed buffer containing a Windows Device Independent Bitmap (DIB) version of this image.
public byte[] ToDibArray( 
   RasterConvertToDibType type 
Public Function ToDibArray( _ 
   ByVal type As RasterConvertToDibType _ 
) As Byte() 
array<byte>^ ToDibArray(  
   RasterConvertToDibType type 


Type of DIB to create.

Return Value

An array of Byte that contains the handle to the Windows DIB.


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

This methods allocates a DIB bitmap and copies the RasterImage to the DIB.

A DIB consists of one of the following:

  • a BITMAPV4HEADER(introduced in Windows 95 and Windows NT 4.0)
  • or a BITMAPV5HEADER (introduced in Windows 2000 and Windows 98)

followed by a color table and then the bitmap data. The resulting DIB type is determined by the value of the type parameter.

The orientation of the image and color order will depend on how the image was loaded into the RasterImage.

For more information on DDBs and DIBs, refer to Introduction: DIBs, DDBs, and the Clipboard.

This function does not support signed images.
