in the documentation it says:

"'lineColor': Line color specification, including transparency. Color value format must be passed as a character array according to the format string '#TTRRGGBB', with 'TT' representing transparency; 'RR', 'GG', and 'BB' representing red, green, and blue colors, respectively. Intensity values are denoted as two-digit hexadecimal numbers ranging from 00 to FF. For example, '#0000FF00' is fullly transparent green and '#FF0000FF' is fully opaque red"

It is true that '#FF0000FF' is fully opaque red, but it can not be this format '#TTRRGGBB'.

documentation and source have been updated so that it now does follow the generally accepted format of TTRRGGBB.
