FOLLOW ANGLE label property

[lorenzetti@…]

For FOLLOW ANGLE label property, when the line is too windy, the letters in the
label are all garbled (either missing or/and in different order).

Bug example

It would be helpful to see some data samples too. It's almost impossible to 
debug without test cases.

Shape data sample for debug

Hi Steve I attached a shape data sample like you request for debug

If data are stored in a database, the following dirty function can temporarily
fix the problem. Function is in PostgreSQL syntax:

-- Patch for Mapserver bug number #2020
-- Strange behavior of short label when ANGLE is set to FOLLOW

CREATE OR REPLACE FUNCTION pad(cString TEXT) RETURNS TEXT AS $$
BEGIN
    RETURN cString || repeat(' ', 4 - char_length(cString));
END;
$$ LANGUAGE plpgsql;

Has anyone tried the padding fix suggested? I don't think the fix for this will be trivial otherwise as it will involve extensions to the underlying algorithm.

This has been fixed (by skipping bad labels) in ticket #3523. I'm gonna call this one a duplicate. -Steve
