AppendFrames(RasterCodecs,Stream,Generic List,Int32,Int32) Method
See Also Example

Leadtools.Jpeg2000 Namespace > Jpeg2000Engine Class > AppendFrames Method : AppendFrames(RasterCodecs,Stream,Generic List,Int32,Int32) Method

codecs: The RasterCodecs object.

stream: A 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.

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