SegmentationOptionsFlags Enumeration

Summary

Flags that identify certain segmentation options.

Syntax

C++/CLI

Python

[FlagsAttribute()] 
public enum SegmentationOptionsFlags

[FlagsAttribute()] 
public enum class SegmentationOptionsFlags

class SegmentationOptionsFlags(Enum): 
   FavorOneBit = 0 
   FavorOneBit = 0 
   WithBackground, FavorTwoBit = 1 
   WithBackground, ForceOneBit = 2 
   WithBackground, ForceTwoBit = 3 
   WithBackground, WithoutBackground = 16

Members

Value	Member	Description
0x00000000	FavorOneBit	Favor 1 bit images whenever there's minimum data loss.
0x00000000	WithBackground	With Background images. Search for background within the image.
0x00000001	FavorTwoBit	Favor 2 bit images whenever there's minimum data loss.
0x00000002	ForceOneBit	Force 1 bit images whenever data loss is within accepted range.
0x00000003	ForceTwoBit	Force 2 bit images whenever data loss is within accepted range.
0x00000010	WithoutBackground	Without Background images.
