L_DispContainerRemoveCobbAngle

Summary

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

Syntax

#include "ltivw.h"

L_LTIVW_API L_INT L_DispContainerRemoveCobbAngle(hCellWnd, nSubCellIndex, hLine)

Parameters

L_HWND hCellWnd

A handle to the window that represents the Medical Viewer Cell.

L_INT 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.

HANNOBJECT hLine

Handle to the one of the two annotation lines that creates the cobb angle.

Returns

Value	Meaning
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, refer to the function L_DispContainerGetCobbAngleValue.
