DeskewExtendedCommandFlags Enumeration
See Also  
Leadtools.ImageProcessing.Core Namespace : DeskewExtendedCommandFlags 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 is to be used, whether the image is mostly text or text and pictures, and whether to use normal or fast rotation.

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. Use this flag to find the angle of rotation.
FillExposedArea Use the color in fillColor to fill areas exposed by rotation.
DoNotFillExposedArea Find the suitable background color to fill areas exposed by rotation automatically. Ignore the FillColor parameter.
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 interpolation when rotating.
RotateResample Perform bilinear interpolation when rotating.
RotateBicubic Perform bicubic interpolation when rotating.
DocumentImage The image contains only text.
DocumentAndTextImage The image contains text and pictures.
UseNormalRotate Use normal rotation speed (high quality).
UseHighSpeedRotate Use fast rotation 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:
GroupFlags
Flags that indicate whether to deskew the image after the method finds the skew angleDeskewImage, ReturnAngleOnly

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
