Just for the record: This has been filed as bug #153635 and it has
now been fixed in both the stable and the development branch.

[Gimp-user] Curve and Alpha problem

[Ivan Zenkov]

Hi, all.

And nevertheless... Why my code doesn't work with alpha?

>(gimp-curves-spline text-layer 4 4 (spline))

I want simple create a transparent text with script-fu, like in
tutorial "Transparent Objects" written by Ron Scott
(http://gug.sunsite.dk/tutorials/ronq2/).  For this purpose I need to
create array on a curve http://img52.exs.cx/img52/5495/curve-alpha.png
that to make the selection area, transparent
http://img79.exs.cx/img79/6625/curve-alpha2.png

But my code for some reason does not work with alpha. Maybe this is a
bug, or most likely I simply have not correctly created array.
Uncompleted code of my script can be found here
http://registry.gimp.org/plugin?id=4729

Please help.
