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

Members
| Member | Description |
|---|---|
| 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. |
Remarks
You can use a bitwise OR (|) to specify one flag from each group.
| 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 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 |
