Fwd: create mask with the comand draw polyf

[Alexandre Santos]

 Dear users,

 created one script for general a mask the continent   for state of
ALagoas-BRAZIL. The file text (anexo) has longitude e latitude.

 I'm not able to create the mask of the state of Alagoas. How do I put a
mask of values outside the state of Alagoas?
