LEADTOOLS JPEG 2000 (Leadtools.Jpeg2000 assembly)
LEAD Technologies, Inc

ExtractFrames Method






System.String containing the name of the JPEG 2000 file from which the frames are being extracted.
System.String containing the name of the JPEG 2000 file to be used to save the extracted frames. This file will contain only the extracted frames.
Frame indices. A list of integers specifying the indices of the frames to be extracted from the input file. All indices should be 0-based.
Extracts the specified frames from the input file, and saves them to a new JPEG 2000 file. This method is available in the Document/Medical Toolkits.
Syntax
public void ExtractFrames( 
   string inputFileName,
   string outputFileName,
   List<int> frames
)
'Declaration
 
Public Sub ExtractFrames( _
   ByVal inputFileName As String, _
   ByVal outputFileName As String, _
   ByVal frames As List(Of Integer) _
) 
'Usage
 
Dim instance As Jpeg2000Engine
Dim inputFileName As String
Dim outputFileName As String
Dim frames As List(Of Integer)
 
instance.ExtractFrames(inputFileName, outputFileName, frames)
public void ExtractFrames( 
   string inputFileName,
   string outputFileName,
   List<int> frames
)
 function Leadtools.Jpeg2000.Jpeg2000Engine.ExtractFrames( 
   inputFileName ,
   outputFileName ,
   frames 
)
public:
void ExtractFrames( 
   String^ inputFileName,
   String^ outputFileName,
   List<int>^ frames
) 

Parameters

inputFileName
System.String containing the name of the JPEG 2000 file from which the frames are being extracted.
outputFileName
System.String containing the name of the JPEG 2000 file to be used to save the extracted frames. This file will contain only the extracted frames.
frames
Frame indices. A list of integers specifying the indices of the frames to be extracted from the input file. All indices should be 0-based.
Remarks
.

This file contains only the extracted frame headers/code streams (not any obtained through the decompressing/recompressing process) so it saves processor time and memory.

This method is very suitable for server applications where multiple clients request specific frames of a JPEG 2000 file. Instead of decompressing and then recompressing the frames this method copies only the needed frame data, saving the data to a new JPEG 2000 file.

Example
For an example, refer to Jpeg2000Engine.AppendGmlData example.
Requirements

Target Platforms: Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2
