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 |
