The ClipRegion structure specifies the location and dimension of a physical rectangular region of a scannable form.
NOTE: A convenient way to obtain a full sheet clip, if xStart, yStart, cxSpan and cySpan are ALL 0 (zero) and only the SideOfSheet specified, the appropriate side is clipped in its entirety and the ClipRegion coordinates are updated with the actual values. In this specific case, if the solution specifies OMR coordinates (ClipHelper.ClipCoordinateSpace), and timing marks are not present on the sheet, or the page margins are invalid, the clipping APIs will return 0,0,0,0 as the clip region to indicate that the API was unable to resolve the OMR coordinates.
This structure is not automation compatible, so is not available to scripting.

|
xStart |
The beginning position along the X-axis of the form. The X-axis contains the cell positions that match the scanner read head. It is also the axis that contains the form ID marks. |
|
yStart |
The beginning position along the y-axis of the form. The y-axis contains the timing marks printed on the guide edge of the form. |
|
cxSpan |
The change in position along the x-axis of the form. |
|
cySpan |
The change in position along the y-axis of the form. The Start and Span members are interpreted on the basis of the ClipHelper.ClipCoordinateSpace property being used. The default is OMR – cells and timing marks. |

const int sosTop - top side const int sosBottom - bottom side |
