<Note>
  This enum is implemented in FRE for Windows.
</Note>

ScanRotationAngleEnum enumeration constants are used to set the image rotation angle (once the page has been scanned).

```
typedef enum {
 SPRA_Rotation0,
 SPRA_Rotation90,
 SPRA_Rotation180,
 SPRA_Rotation270
} ScanRotationAngleEnum;
```
