Syntax

C++/CLI

Python

public MrcTextCompression2BitCoder Text2BitCoder { get; set; }

public: 
property MrcTextCompression2BitCoder Text2BitCoder { 
   MrcTextCompression2BitCoder get(); 
   void set (    MrcTextCompression2BitCoder ); 
}

Text2BitCoder # get and set (MrcCompressionOptions)

Property Value

All possible values are found in MrcTextCompression2BitCoder.

Remarks

This property is valid only when saving in LEAD Proprietary T44 format using the MrcSegmenter.SaveImage method. This property is used only if MrcImageFormat.Mrc, MrcImageFormat.MrcTif, or MrcImageFormat.MrcPdf is set in the format parameter of either MrcSegmenter.SaveImage or MrcSegmenter.SaveImageT44 methods.

Example

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.Mrc; 
 
public void SaveImageExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "MRCSegmentation.mrc")); 
 
   MrcSegmenter segmenter = new MrcSegmenter(image, Path.Combine(LEAD_VARS.ImagesDir, "MRCSegmentation.sgm")); 
 
   MrcCompressionOptions compressionOptions = MrcCompressionOptions.Empty; 
 
   compressionOptions.MaskCoder = MrcMaskCompression.FaxG31D; 
   compressionOptions.PictureCoder = MrcPictureCompression.Jpeg; 
   compressionOptions.PictureQualityFactor = 10; 
   compressionOptions.Grayscale8BitCoder = MrcGrayscaleCompression8BitCoder.GrayscaleCmw; 
   compressionOptions.Grayscale8BitFactor = 2; 
   compressionOptions.Grayscale2BitCoder = MrcGrayscaleCompression2BitCoder.Jbig2; 
   compressionOptions.Text2BitCoder = MrcTextCompression2BitCoder.Jbig2Bit; 
 
   try 
   { 
      segmenter.SaveImage(image, Path.Combine(LEAD_VARS.ImagesDir, "Out_Result.Mrc"), MrcImageFormat.Mrc, compressionOptions, codecs); 
   } 
   catch (Exception e) 
   { 
      MessageBox.Show(e.Message); 
   } 
} 
 
static class LEAD_VARS
