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.


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 hAttachedLine

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.
