I've just started looking at the PIL module. There doesn't seem to be a
close method. Is that right? I just open the image file, and never need to
close it?

PIL works with image objects, not files. It automagically closes the
file when it doesn't need it any more.
If you don't trust PIL, do this:
fp = open(filename, "rb")
im = Image.open(fp) # open from file object
im.load() # make sure PIL has read the data
fp.close()
</F>

Ah, OK. As a Python newbie, it's these details I still need to think through
properly.
If you don't trust PIL, do this:
Oh, I trust it. Really!

In the new Python game I'm developing, I need to crop out individual
tiles from larger tilesets, and maintain transparency. Unfortunately,
I've run into major deficiencies in both Tkinter and PIL (PyGame,
wxPython, PyQt, etc. are not really suitable for this program, for a
number of reasons, and I have zero interest in discussing why right
now).
Since the Tkinter.PhotoImage.copy() method doesn't allow a region
parameter, I have to save...

Is there a way to copy a PIL image to windows clipboard (as a dib
image or a bitmap, I suppose)?
What I would like to accomplish is to do a fast copy and paste of
images from my python application to a windows application such as
powerpoint. A slower way is to use files, which is what I am doing at
the moment.
Thanks in advance.

Does anyone know how to embed PIL into a py2exe program.
As far as I can tell PIL is not finding its plugins for Image I/O,
they are imported dynamically as required. So I cant load or save
pictures
I tried making a copy of the plugin files to the application
directory, but I've had no luck in making the code see the files
I'd be grateful for any suggestion.

Hi,
I'm writing an app that downloads images. It rejects images that are
under a certain size - whithout downloading them completely. I've
implemented this using PIL, by downloading the first K and trying to
create a PIL image with it. PIL raises an exception because the file is
incomplete, but the image object is initialised with the image
dimensions, which is what I need. It actualy works well enough, but I'm
concerened about...

Hi
I've spent a good majority of my day trying to figure out how to have
PIL 1.1.5 working on my OSX 10.3.9_PPC machine. I'm still stuck and I
have not gotten anywhere. Could somebody please help me...
I've scoured all the documentation, google, and mailing lists to no
avail. I believe the problem may lay in a jpeglib problem with OSX
10.3.9, or a python paths problem.

Heyas
So I've been messing around with the PIL and PNG's and came across a
little problem with PNG's.
So just to clarify, I'm running with the standard ubuntu 8.04 python-
imaging package that installs zlib and all the other goodies that go
along to make the PIL work with PNG's nicely.
So this works fine:

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
