ImageQualityFactor Property








Leadtools.Codecs Namespace > CodecsJbig2SaveOptions Class : ImageQualityFactor Property
Gets or sets the degree of loss in the compression process for non-text areas.
Syntax
public int ImageQualityFactor {get; set;}
'Declaration
 

Public Property ImageQualityFactor As Integer
'Usage
 

Dim instance As CodecsJbig2SaveOptions
Dim value As Integer
 
instance.ImageQualityFactor = value
 
value = instance.ImageQualityFactor
public int ImageQualityFactor {get; set;}
@property (nonatomic, assign) NSUInteger imageQualityFactor
public int getImageQualityFactor()
public void setImageQualityFactor(int imageQualityFactor)
            
 <br/>get_ImageQualityFactor();<br/>set_ImageQualityFactor(value);<br/>Object.defineProperty('ImageQualityFactor'); 
public:
property int ImageQualityFactor {
   int get();
   void set (    int value);
}

Property Value

An integer value that determines the degree of loss in the compression process for non-text areas. The value of 0 means lossless while any other value means lossy. The default value is 0.
