SaveComposite(RasterCodecs,Stream,List<CompositeJpxImages>,Jpeg2000FileFormat,Int32,Int32) Method

Saves a CompositeJpxImages list to a stream in any of the supported JPEG 2000 file formats. This method is available in the Document/Medical Toolkits.

public:
void SaveComposite( 
   RasterCodecs^ codecs,
   Stream^ stream,
   List<CompositeJpxImages^>^ compositeImages,
   Jpeg2000FileFormat format,
   int bitsPerPixel,
   int qualityFactor
)

Parameters

codecs: The Leadtools.Codecs.RasterCodecs object.
stream: A System.IO.Stream to which the image data will be saved.
compositeImages: List of CompositeJpxImages layer image data that will be saved
format: Output JPEG 2000 file format. For valid values, refer to Jpeg2000FileFormat.
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 that are currently set will also be saved in this file
