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

Summary

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

Syntax

C++

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

Public Overloads Sub AppendFrames( _ 
   ByVal codecs As Leadtools.Codecs.RasterCodecs, _ 
   ByVal stream As Stream, _ 
   ByVal compositeImages As List(Of CompositeJpxImages), _ 
   ByVal bitsPerPixel As Integer, _ 
   ByVal qualityFactor As Integer _ 
)

public: 
void AppendFrames(  
   Leadtools.Codecs.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.
