python-fu grid plugin

Hi

I'm having problems with pdb.plug_in_grid. This function works ok if applied on an indexed image, but fails (only draws vertical lines) if applied on a RGB image.

What's wrong?

Regards.

EEEK!! :-)

Bug in the grid.c plug-in. I will see if it is something I can fix - anyway, if you want, you acan open a bugzilla bug for it already - bugzilla.gnome.org

I already could verify it is not python-fu related - it is a problem in the plug-in itself.

I managed to fix it.
I attached a patch to bug #156750 - http://bugzilla.gnome.org/show_bug.cgi?id=156750

The plug-in was just ignoring the alpha parameter passed in the calls, letting in grabage in it's place. So, sometimes the call would work, sometimes don't.

The fact that the script passes garbage is not exactly the fault of the plug-in. Colors passed via the PDB do actually have an alpha channel. But since this is a seldomly used feature and since the grid API is documented to use the opacity values, your fix seems like the right thing to do.
