I would like to create a transparency gradient over an image using
PIL. But I don't have a clue how to do this...
Is there anyone out here who could give me some advise?

Phatch (PHoto & bATCH) is an application based on PIL. Its actions
contain many useful PIL recipes, such as applying a transparency
gradient to an image. You basically need to create an 1pxx256px
grayscale image which goes from 0 to 255. After that you can stretch
it to the image size and add it as an alpha channel. You'll find the
source code for this in the phatch/actions/mask.py Every action
contains a 'raw' PIL function that can work independently outside the
context of Phatch. This is by design, inspired by the MVC model in
which you could see PIL as the model and Phatch as the View.

You can get Phatch at:

Read first *carefully* the installation instructions for your
platform:

Thanks for the inspiration!
This what I did (Using your Python Editor (SPE), I really like to work
with SPE, keep up the good work!!):

#############################################
import Image, os
p = # path to image file

im = Image.open(p)
# check if im has Alpha band...
if im.mode != 'RGBA':
im = im.convert('RGBA')
# create a vertical gradient...
gradient = Image.new('L', (1,255))
for y in range(255):
gradient.putpixel((0,254-y),y)
# resize the gradient to the size of im...
alpha = gradient.resize(im.size)
# put alpha in the alpha band of im...
im.putalpha(alpha)
# Save as png...
im.save(os.path.splitext(p)[0] + '.png', 'PNG

#############################################

Thought you got kicked cuz your nick/id whatever the fuck (you young people
with your lulz and your motorcars an' elektricitee!) was inactive.

I don't see any censorship in the above. I don't see that you were saying
things that caused people to freak out and get all pissed off.

In fact, I don't see that you were saying anything.

Not exactly a brilliant example of censorship and violation of that nifty
kewl 1st amendment thingie.

Freedom of Assembly is part of the 1st amendment. It does not necessarily
involves saying anything.

It's obviously a private chat group.

And they are apparently rather paranoid -- which is within their
rights. You might have been... duh-duh-duh-duh! OSA!!!!

EEEEEEEK!

Anyway -- why care?

And you can learn a lot about a group by how it treats -- Oooooo --
Outsiders!

Free speech is not guaranteed for privately-run enterprises. So it
goes,

They are well within their rights to kick anyone out. Just... learn
about that group based on your own experience. I know *I* have
learned something about that venue based on your story and the
responses to it here from those who are apparently its denizens.

Thanks for the report and the post of the chat taking place while. It
helps to see how lurkers are treated there (among other things).

Gives good insight into the folks who hang out there. :)

Yeah, whereas the forums and chat rooms maintained by others never ever
mention OSA.

(gentle sarcasm)

Wait a minute. All they did was kick off an inactive ID. There was no
"treatment" of anyone about it.

There wasn't ~any~ speech to guarantee, protest, go along with, kick off. It
was an inactive nick.

From what Henri says, it wasn't a question of kicking anyone out.

Would you like to know what happened when a friend of mine who is well known
in critical circles tried to join in and log into Lermanet? Banned for
abuse. The person had never done anything abusive on any forum, anywhere,
never been in CofS, none of that.

Gee, thanks a lot. I hang out there as do a number of very nice people of
whom I'm quite fond.

Personally, I think this thread is informative and indicates much about some
people- but not the ones to whom you allude here.

Duh..............

IRC and #altreligionscientology isn't covered by the U.S constitution or
any other constitution for that matter. IRC is not a U.S network, it's a
global network covering and emanating from countless countries world
wide.

Please oh Xenu answer me why so many U.S citizens believe that the
Internet is some American thingy only?

Please oh Xenu answer me why so many U.S citizens believe that they have
the best constitution and legal system on the entire planet, when they
are countless examples of the opposite?

Please oh Xenu, answer me....
