Save(RasterCodecs,string,RasterImage,Jpeg2000FileFormat,int,int) Method

Summary
Saves a Leadtools.RasterImage to a file in any of the supported JPEG 2000 file formats. This method is available in the Document/Medical Toolkits.
Syntax

C++
  
Public Overloads Sub Save( _ 
   ByVal codecs As RasterCodecs, _ 
   ByVal fileName As String, _ 
   ByVal image As RasterImage, _ 
   ByVal format As Jpeg2000FileFormat, _ 
   ByVal bitsPerPixel As Integer, _

void Save(  
   RasterCodecs^ codecs, 
   String^ fileName, 
   RasterImage^ image, 
   Jpeg2000FileFormat format, 
   int bitsPerPixel, 
   int qualityFactor 
)  

Parameters

codecs
The Leadtools.Codecs.RasterCodecs object.

fileName
System.String containing the name of the file currently being saved.

image
The Leadtools.RasterImage object that holds the image data.

format
Output JPEG 2000 file format. For valid values, refer to Jpeg2000FileFormat.

bitsPerPixel
The 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 of the engine boxes that are currently set will also be saved in this file
