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. Supported in Silverlight, Windows Phone 7

Syntax

Visual Basic (Declaration) 
Public Property Flags As BlankPageDetectorCommandFlags
Visual Basic (Usage)Copy Code
Dim instance As BlankPageDetectorCommand
Dim value As BlankPageDetectorCommandFlags
 
instance.Flags = value
 
value = instance.Flags
C# 
public BlankPageDetectorCommandFlags Flags {get; set;}
C++/CLI 
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

Example

Run the Leadtools.ImageProcessing.Core.BlankPageDetectorCommand on an image and determine whether it is blank.
