L_LTIVW_API L_INT L_DispContainerRemoveCobbAngle(hCellWnd, nSubCellIndex, hLine)

L_HWND hCellWnd;

handle to the cell window

L_INT nSubCellIndex;

index into the image list attached to the cell

HANNOBJECT hLine;

handle for one of the cobb angle annotation lines

Removes the cobb-angle value using one of the two lines that is used to create the cobb angle.

Parameter Description
hCellWnd A handle to the window that represents the Medical Viewer Cell.
nSubCellIndex A zero-based index into the image list attached to the cell specified in nCellIndex. This sub-cell is the one where that the cobb-angle is placed. Pass -2 to refer to the selected sub-cell. If the cell contains 1 frame then the nSubCellIndex should be 0.
hLine Handle to the one of the two annotation lines that creates the cobb angle.

Returns

SUCCESS The function was successful.
< 1 An error occurred. Refer to Return Codes.

Comments

To create a cobb angle, add two lines to the sub-cell / cell, then pass them to the function L_DispContainerAddCobbAngle.

To get the cobb angle value, please refer to the function L_DispContainerGetCobbAngleValue.
