Flags Property (BlankPageDetectorCommand)

Example 





Gets or sets flags that indicate whether the page is empty or noisy, whether to ignore bleed-through, whether to ignore lines, whether to use the active area and whether to use default margins or the user-specified margins. .NET support WinRT support Silverlight support
Syntax
public BlankPageDetectorCommandFlags Flags {get; set;}
'Declaration
 
Public Property Flags As BlankPageDetectorCommandFlags
'Usage
 
Dim instance As BlankPageDetectorCommand
Dim value As BlankPageDetectorCommandFlags
 
instance.Flags = value
 
value = instance.Flags
public BlankPageDetectorCommandFlags Flags {get; set;}
 get_Flags();
set_Flags(value);
public:
property BlankPageDetectorCommandFlags Flags {
   BlankPageDetectorCommandFlags get();
   void set (    BlankPageDetectorCommandFlags value);
}

Property Value

Gets or sets flags that indicate whether the page is empty or noisy, whether to ignore bleed-through, whether to ignore lines, whether to use the active area and whether to use default margins or the user-specified margins. The default value is BlankPageDetectorCommandFlags::DetectEmptyPage | BlankPageDetectorCommandFlags::DontIgnoreBleedThrough | BlankPageDetectorCommandFlags::DontDetectLinedPage | BlankPageDetectorCommandFlags::DontUseActiveArea | BlankPageDetectorCommandFlags::UseDefaultMargins
