L_INT LImageViewerCell::RemoveCobbAngle(nSubCellIndex, hAttachedLine);
Removes the cobb-angle value using one of the two lines that is used to create the cobb angle.
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.
Reserved for future use. Pass 0.
| Value | Meaning |
|---|---|
| SUCCESS | The function was successful. |
| < 1 | An error occurred. Refer to Return Codes. |
To create a cobb angle, add two lines to the sub-cell / cell, then pass them to the function LImageViewerCell::AddCobbAngle.
To get the cobb angle value, use the function LImageViewerCell::GetCobbAngleValue.
