L_INT LImageViewerCell::AddCobbAngle(nSubCellIndex, hFirstLine, hSecondLine)

Creates a cobb-angle, which is a text display the angle between two lines, using the specified annotation lines (hFirstLine, hSecondLine).


L_INT nSubCellIndex

A zero-based index into the image list attached to the cell. This sub-cell contains the image that contains the annotation container. Pass -2 to refer to the selected sub-cell.


Handle of the first annotation line that is used to create the cobb-angle.


Handle to the second annotation line that is used to creat the cobb-angle.


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


To retrieve the cobb angle value, use the function LImageViewerCell::GetCobbAngleValue.

To delete a cobb angle, use the function LImageViewerCell::RemoveCobbAngle.
