'Declaration
 
Public Overloads Function FeedGetInformation( _
   ByVal data As IBuffer, _
   ByVal offset As Integer, _
   ByVal length As Integer _
) As Boolean

'Usage
 
Dim instance As RasterCodecs
Dim data As IBuffer
Dim offset As Integer
Dim length As Integer
Dim value As Boolean
 
value = instance.FeedGetInformation(data, offset, length)

public bool FeedGetInformation( 
   IBuffer data,
   int offset,
   int length
)

 function Leadtools.Codecs.RasterCodecs.FeedGetInformation(IBuffer,Int32,Int32)( 
   data ,
   offset ,
   length 
)

public:
bool FeedGetInformation( 
   IBuffer^ data,
   int offset,
   int length
)

Parameters

data: The image file unmanaged memory data.
offset: Offset from the beginning of the buffer to where the image data starts.
length: Total size (in bytes) of the image data.

Return Value

true if the get information process requires more data; false, otherwise. When this method returns false, you can break out of the loop and call StopFeedGetInformation to obtain the CodecsImageInfo object containing the information about the image file.

Remarks

Use this method with the StartFeedGetInformation and StopFeedGetInformation methods.
