Description
This function is used to insert lines on the Maps EWO. The function returns the unique line number inside the defined layer which can be used for further operations, such as adding points (defined by coordinates) to the line.
The function only creates an empty line. To make it visible at least two points must be added by using the function addPointToLine(), e.g.
int iLine = Maps_ewo1.addLine("red", 2);
Maps_ewo1.addPointToLine(iLine, 47.830147, 16.532771);
Maps_ewo1.addPointToLine(iLine, 90, 0);Assignment
