public: void ExtractFrames( String^ inputFileName, String^ outputFileName, List<int>^ frames ) |
Parameters
- inputFileName
- String containing the name of the JPEG 2000 file from which the frames are being extracted.
- outputFileName
- 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.
For an example, refer to Jpeg2000Engine.AppendGmlData example.
. 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.
Target Platforms: Microsoft .NET Framework 2.0, Windows 98, Windows NT 4.0, Windows Millennium Edition, Windows 2000, Windows XP Home Edition, Windows XP Professional, Windows Server 2003 family
