AppendFrames(RasterCodecs,Stream,List<CompositeJpxImages>,Int32,Int32) Method

Appends new frames to a currently existing JPEG 2000 stream. This method is available in the Document/Medical Toolkits.

Syntax

Visual Basic
C#
Objective-C
Java
C++

public void AppendFrames( 
   RasterCodecs codecs,
   Stream stream,
   List<CompositeJpxImages> compositeImages,
   int bitsPerPixel,
   int qualityFactor
)

'Declaration
 
Public Overloads Sub AppendFrames( _
   ByVal codecs As RasterCodecs, _
   ByVal stream As Stream, _
   ByVal compositeImages As List(Of CompositeJpxImages), _
   ByVal bitsPerPixel As Integer, _

'Usage
 
Dim instance As Jpeg2000Engine
Dim codecs As RasterCodecs
Dim stream As Stream
Dim compositeImages As List(Of CompositeJpxImages)
Dim bitsPerPixel As Integer
Dim qualityFactor As Integer
 
instance.AppendFrames(codecs, stream, compositeImages, bitsPerPixel, qualityFactor)

public:
void AppendFrames( 
   RasterCodecs^ codecs,
   Stream^ stream,
   List<CompositeJpxImages^>^ compositeImages,
   int bitsPerPixel,
   int qualityFactor
)

Parameters

codecs: The Leadtools.Codecs.RasterCodecs object.
stream: A System.IO.Stream to which the new frame data will be saved.
compositeImages: List of CompositeJpxImages containing the layer image data being appended.
bitsPerPixel: Resulting file's pixel depth. Possible values are: 8, 12, 16, 24, 32, 48, 64, and 0. A value of zero [0] means that each image will be saved with its bits per pixel value, if that value is equal to one of the possible values (8, 12, 16, 24, 32, 48, or 64).
qualityFactor: Quality factor. This value determines the degree of loss in the compression process. Possible values are from 0 to 255. A value of zero (0) represents lossless compression. Values between 1 and 255 are interpreted as a compression ratio.

Remarks

All engine boxes will be reset.
