InvertedPageCommandFlags Enumeration

Summary

Options for the InvertedPageCommand class.

Syntax

Objective-C

C++/CLI

Java

Python

[FlagsAttribute()] 
public enum InvertedPageCommandFlags

typedef NS_OPTIONS(NSUInteger, LTInvertedPageCommandFlags)

public final class InvertedPageCommandFlags 
    extends java.lang.Enum<InvertedPageCommandFlags>

[FlagsAttribute()] 
public enum class InvertedPageCommandFlags

class InvertedPageCommandFlags(Enum): 
   None = 0 
   None = 0 
   Process, NoProcess = 1 
   Process, ExcludeBorder = 2 
   Process, UseZones = 4

Members

Value	Member	Description
0x00000000	None	Default value. Checks and corrects the image if it is inverted. This is the same as specifying the Process flag.
0x00000000	Process	Checks and corrects the image if it is inverted. The InvertedPageCommand.IsInverted will be set to true if the command inverted the image, false; otherwiseThis flag cannot be used with NoProcess.
0x00000001	NoProcess	Only determine whether the image is inverted but do not change the image data. The InvertedPageCommand.IsInverted will be set to true if the image is inverted; otherwise, falseThis flag cannot be used with Process.
0x00000002	ExcludeBorder	Excludes White or Black borders from the calculations.
0x00000004	UseZones	An advanced version that is able to detect figure images before inverting them. This option is slower than the other options.This flag cannot be used with ExcludeBorder.

Remarks

You can use a bitwise OR ( | ) to specify one or more flags.

The InvertedPageCommand enumeration is used as the type for the InvertedPageCommand.Flags property.
