SetImageRotate

unsigned int WINAPI SetImageRotate(int iRotate)

Description

This function will cause data output from the SDK to be rotated on one or both axes. This

rotate is not done in the camera, it occurs after the data is retrieved and will increase

processing overhead. If the rotation could be implemented by the user more efficiently

then use of this function is not recomended. E.g writing to file or displaying on screen.

Parameters

int iRotate: Rotation setting

0 - No rotation

1 - Rotate 90 degrees clockwise

2 - Rotate 90 degrees anti-clockwise

If this function is used in conjunction with the

SetImageFlip function the rotation will occur

before the flip regardless of which order the functions are called.

180 degree rotation can be achieved using the SetImageFlip function by selecting both

horizontal and vertical flipping.

Return

unsigned int

DRV_SUCCESS

DRV_NOT_INITIALIZED

DRV_P1INVALID

All parameters accepted.

System not initialized.

Rotate parameter invalid.
