PictureQualityFactor Property

Summary
Gets or sets the compression quality for JPEG, CMP and CMW compression.
Syntax
C#
C++/CLI
Python
public int PictureQualityFactor { get; set; } 
public: 
property int PictureQualityFactor { 
   int get(); 
   void set (    int ); 
} 
PictureQualityFactor # get and set (MrcCompressionOptions) 

Property Value

Possible values are between 2 and 255, where 2 is the highest quality and 255 is the most compression. If the PictureCoder is CMW or JPEG lossless compression, the PictureQualityFactor should be 0.

Example
C#
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 
{ 
   public const string ImagesDir = @"C:\LEADTOOLS23\Resources\Images"; 
}
