DeskewCommandFlags Enumeration

Summary

Indicates whether to deskew the image, which background color to use, whether to deskew the image if the skew angle is very small, which type of interpolation to use, whether the image contains mostly text, and whether to use normal or fast rotation. This enumeration has a System.FlagsAttribute attribute that allows a bitwise combination of its member values.

Syntax

C++

[DataContractAttribute(Namespace="http://Leadtools.Services.ImageProcessing.DataContracts/2009/01", Name="DeskewCommandFlags")] 
[FlagsAttribute()] 
public enum DeskewCommandFlags

<FlagsAttribute()> 
Public Enum DeskewCommandFlags  
   Inherits System.Enum 
   Implements System.IComparable, System.IConvertible, System.IFormattable

[DataContractAttribute(Namespace="http://Leadtools.Services.ImageProcessing.DataContracts/2009/01", Name="DeskewCommandFlags")]

Members

Value	Member	Description
0x00000000	NoThreshold	Deskew (rotate) the image for any deskew angle value.
0x00000000	UseNormalRotate	Rotate at normal speed (high quality).
0x00000000	RotateLinear	Do not perform any interpolation methods when rotating.
0x00000000	DocumentImage	The image contains only text.
0x00000000	DeskewImage	Deskew (rotate) the image.
0x00000000	FillExposedArea	(0x00000000)Use the fill color (in the FillColor property, or the fillColor parameter of the Constructor) to fill the areas exposed by rotation.
0x00000001	ReturnAngleOnly	Do not deskew (rotate) the image. Generally this flag is used to find the angle of rotation.
0x00000010	DoNotFillExposedArea	Find the suitable background color used to fill areas exposed by rotation automatically. FillColor is ignored in this case.
0x00000100	Threshold	(0x00000000)Do not deskew the image if the deskew angle is very small (less than 0.5 degrees).
0x00001000	RotateResample	Perform bilinear interpolation when rotating.
0x00002000	RotateBicubic	Perform bicubic interpolation when rotating.
0x00010000	DocumentAndPictures	The image contains text and pictures or light text.
0x00100000	UseHighSpeedRotate	Rotate at high speed (moderate quality, only for 1-bit images).

Remarks

You can use a bitwise OR ( ¦ ) to specify one flag from each of the following groups:

Group	Flags
Indicates whether to deskew the image after the method finds the skew angle.	DeskewImage, ReturnAngleOnly
Indicates which background color to use.	FillExposedArea, DoNotFillExposedArea
Indicates whether to deskew the image if the skew angle is very small.	NoThreshold, Threshold
Specifies which type of interpolation to use.	RotateLinear, RotateResample, RotateBicubic
Indicates whether the image contains mostly text, or text and pictures.	DocumentImage, DocumentAndPictures
Indicates whether to use normal or fast rotation speed. Normal results in high quality. Fast results in moderate quality and is only intended for 1-bit images.	NormalSpeedRotate, HighSpeedRotate
