Instructions from the irc.

Hi there, I am the Blur Filter.              
14:56 (Treatz) how do I make sparkles?
14:58 (drc) Use the sparkle plug-in?
14:59 (schumaml) Treatz: it works on bright sports, so add a few white 
                  spots with a 1px brush
14:59 (Treatz) Hmm
14:59 (Treatz) Don't understand
14:59 (drc) Treatz: Sparkle plug-in creates a sparcle on completely white 
             pixels.
14:59 (schumaml) which part ?
15:00 (Treatz) how to use sparkles
15:00 (Treatz) I tride the noise effects but they didn't look like stars
15:00 (pgimeno) I think I understand the problem
15:01 (pgimeno) The plug-ins keep the transparency channel untouched.
15:01 (pgimeno) And you want to paint over a transparent zone, right?
15:01 (schumaml) maybe "keep transparency" is checked...
15:02 (drc) Treatz: http://tigert.gimp.org/gimp/tutorials/the_bazaar_1999/ 
             has a starfield as one part.
15:02 (Treatz) keep transparency wasn't checked
15:03 (tigert) you need to play with curves to get stars
15:03 (Treatz) and it didn't work when I checked it
15:03 (drc) Treatz: 
             http://www.sf.edu/jhlavacek/tutorial/starfield/starfield.html 
             Too.
15:03 (tigert) since you want only the brightest ones
15:05 (Treatz) I don't want a black background. :(
15:06 (schumaml) Treatz: this is trivial to remove
15:06 (Treatz) how do you remove it?
15:06 (carol) Treatz: what do the stars look like where you live?
15:07 (schumaml) Treatz: color to alpha plug-in
15:07 (tigert) Treatz: you make the stars on one layer
15:07 (tigert) Treatz: set mode to "addition" or such
15:07 (tigert) and make a blue gradient background
15:07 (tigert) and adjust stars opacity
15:14 (Treatz) eh?
15:15 (Treatz) okay color to alpha worked.
15:16 (schumaml) btw, GFlare works on transparent layers here
15:16 (schumaml) Sparkles too
