DeskewCommandFlags Enumeration

Flags that indicate 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.

Members

Member	Description
DeskewImage	Deskew (rotate) the image.
DocumentAndPictures	The image contains text and pictures or light text.
DocumentImage	The image contains only text.
DoNotFillExposedArea	Determine the suitable background color for fill areas exposed by rotation automatically. FillColor is ignored in this case.
DoNotPerformPreProcessing	Don't perform preprocessing on the image before deskewing it.
DoNotUseCheckDeskew	Perform the ordinary deskew. Do not perform any of the bank check algorithms.
FillExposedArea	Use the fill color (in the FillColor property, or the fillCOlor parameter of the Constructor) to fill areas exposed by rotation.
NoThreshold	Deskew (rotate) the image for any deskew angle value.
PerformPreProcessing	Perform preprocessing on the image before deskewing it.
ReturnAngleOnly	Don't deskew (rotate) the image. Generally this flag is used to find the angle of rotation.
RotateBicubic	Perform bicubic interpolation when rotating.
RotateLinear	Don't perform any interpolation methods when rotating.
RotateResample	Perform bilinear interpolation when rotating.
Threshold	Do not deskew the image if the deskew angle is very small (less than 0.5 degrees).
UseCheckDeskew	Use the bank check algorithm to deskew the image. This algorithm considers many features common to standard bank checks in order to determine orientation.
UseExtendedDeskew	Use an alternative algorithm to deskew the image, this algorithm is equivalent to the obsolete command DeskewCommandExtended. This flag when set, the properties DeskewCommand.AngleRange and DeskewCommand.AngleResolution are used.
UseHighSpeedRotate	Use fast rotation speed (moderate quality, only for 1-bit images).
UseLineDetectionCheckDeskew	Use the bank check line detection algorithm to deskew the image.
UseNormalDetection	Don't use the selective detection technique which is more accurate.
UseNormalRotate	Use normal rotation speed (high quality).
UseSelectiveDetection	Use the selective detection technique which is faster.

Remarks

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

Group	Flags
Flags that indicate whether to deskew the image after the method finds the skew angle.	DeskewImage, ReturnAngleOnly
Flags that indicate which background color to use.	FillExposedArea, DoNotFillExposedArea
Flags that indicate whether to deskew the image if the skew angle is very small.	NoThreshold, Threshold
Flags that specify which type of interpolation to use.	RotateLinear, RotateResample, RotateBicubic
Flags that indicate whether the image contains mostly text, or text and pictures.	DocumentImage, DocumentAndPictures
Flags that indicate 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
