DeskewCheckCommandFlags Enumeration

Leadtools.ImageProcessing.Core Namespace : DeskewCheckCommandFlags Enumeration



Support for this function will be discontinued in the next major release of LEADTOOLS. Use DeskewCommand instead. Flags that indicate whether to deskew the image and which background color to use.

This enumeration has a FlagsAttribute attribute that allows a bitwise combination of its member values.

Members

MemberDescription
DeskewImage Deskew (rotate) the image.
ReturnAngleOnly Do not deskew (rotate) the image. Generally this flag is used to find the angle of rotation.
FillExposedArea Use the fill color (in the FillColor property, or the fillCOlor parameter of the Constructor) to fill the areas exposed by rotation.
DoNotFillExposedArea Find the suitable background color used to fill areas exposed by rotation automatically. FillColor is ignored in this case.
NoThreshold Deskew (rotate) the image for any deskew angle value.
Threshold Do not deskew the image if the deskew angle is very small (less than 0.5 degrees).
RotateLinear Do not perform any interpolation methods when rotating.
RotateResample Perform bilinear interpolation when rotating.
RotateBicubic Perform bicubic interpolation when rotating.
DocumentImage The image contains only text.
DocumentAndPictures The image contains text and pictures or light text.
UseNormalRotate Rotate at normal speed (high quality).
UseHighSpeedRotate Rotate at high speed (moderate quality, only for 1-bit images).
DoNotUseCheckDeskew Do not perform any of the bank check algorithms. Perform the ordinary deskew.
UseNormalCheckDeskew Use the bank check algorithm to deskew the image. This algorithm considers many features common to standard bank checks in order to determine orientation.
UseLineDetectionToDeskewCheck Use the line detection algorithm to deskew the image.

Example

Remarks

You can use a bitwise OR (|) to specify one flag from each group.
GroupFlags
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 the type of interpolation to be used.RotateLinear, RotateResample, RotateBicubic
Flags that indicate whether the image is mostly text, or text and pictures.DocumentImage, DocumentAndPictures
Flags that indicate the rotation type: normal or fast. Normal gives high quality, whereas fast gives moderate quality and is only for 1-bit images.NormalSpeedRotate, HighSpeedRotate
Flags that indicate whether to deskew the image using ordinary deskew, bank check deskew, or line detection deskew.DoNotUseCheckDeskew, UseNormalCheckDeskew, UseLineDetectionToDeskewCheck
