Yes, just make sure to check the given output filename + the given
extension.
Oh; you're talking about illegal *file* names (as opposed to map
names)?
No sorry, I meant map names.
BTW anyone know how to give an empty extension in the tcltk gui ? On the
command line I can use extension="", but in the gui I get an error
because of an illegal ".
On the command line, using:
extension=""
is the same as using just:
extension=
The quotes are removed by the shell.
Thanks for the info.
More generally, Tcl requires any quotes to go around the entire
"word", so a command line argument such as:
text="hello world"
would need to be entered as
"text=hello world"
or:
{text=hello world}
So what would be the tcltk gui equivalent of extension= or extension=""
? "Extension" is a text field to be filled in. So as a result you get a
command line with extension=anything you put in the field (without any
quotes. However, leaving the field empty does not work, as it is a
required field. '""' doesn't work either. Would it work if the gui used
curly braces around the result ? I.e. how to indicate an empty string to
the gui ?
