Comments

The DTWAIN_SetOrientation function sets the current orientation for the Source Source when acquiring pages.

The Orientation is the orientation to set. If bSetCurrent is TRUE, the orientation is set to the value specified by Orientation. If bSetCurrent is FALSE, the default orientation is set, and the Orientation argument is ignored. The value of Orientation can be any one of the Orientation Constants.

The TWAIN Source must support setting orientation (see DTWAIN_IsOrientationSupported)
