The DeskewCommandFlags Enumeration is available in LEADTOOLS Document and Medical Imaging toolkits.
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.

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 | Find the suitable background color used to fill areas exposed by rotation automatically. FillColor is ignored in this case. |
| FillExposedArea | Use the fill color (in the FillColor property, or the fillColor parameter of the Constructor) to fill the areas exposed by rotation. |
| NoThreshold | Deskew (rotate) the image for any deskew angle value. |
| ReturnAngleOnly | Do not deskew (rotate) the image. Generally this flag is used to find the angle of rotation. |
| RotateBicubic | Perform bicubic interpolation when rotating. |
| RotateLinear | Do not 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). |
| UseHighSpeedRotate | Rotate at high speed (moderate quality, only for 1-bit images). |
| UseNormalRotate | Rotate at normal speed (high quality). |
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 |
