Gimp-perl: drawing a line and refreshing the gradients

[josvanr]

Hi!


I'm learning to write Gimp-perl scripts. Just now, I 
tried to draw a line with a width of one pixel. From within 
gimp this can be done by selecting the 'Circle (01)' brush.
However, when I do this in a script, the line width drawn gets
to be two pixels wide. I can't figure out how to change this
behaviour.

Second, In my script, I generate a custom gradient: I just
put some numers in a text file. Now, I'd like to use this gradient
from that point on, but as it turns out, I can't use it, until
I pressed 'refresh' from the gradients editor. Is there any 
way of 'refreshing' the gradients from a perls script, without
user interaction?

I included the test script I used, below; maybe some of you
have a good tip for me

regards,
