FUNCTION c_rtiddr(inddr,rot)
struct DDR *inddr; long *rot;
Input DDR structure to be updated
Rotation amount in 90 degree increments:
= 1: 90 degrees = 2: 180 degrees = 3: 270 degrees = 4: Horizontal flip = 5: Vertical flip
The c_rtiddr() call is used to update the projection information in a DDR structure for rotations of 90 degree increments (ie. 90, 180, 270) and for horizontal and vertical flips.
c_rtiddr() returns
E_SUCC (0) --> successful completion E_FAIL (-1) --> operation failed
