One of the things I really like about the IMP webmail package is that it makes it easy for people to provide links to attachments rather than sending the files. It automatically copies the files to the web server, adding the links to the bottom of the message. I don't generally like web e-mail interfaces, but do use IMP when dealing with large attachment.

I did not know that the limit is so low (40 KB). I did really consider to put the images on a web server, but the Berlios ftp server was down last night. (It's the only one where I have bookmarked the upload directory.) It was also late and I wanted to send the message before it would become pointless; so I sent it with the images attached. To the moderators: Thank you for posting my big message. Kind regards, Eike. ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor

Figure out the total size sending a megabyte+ mail message to hundreds of list recipients. Most mailing lists limit the size of messages to 40k or less. While large messages aren't much of an issue on broadband connections, they can be a problem for those on dialup or with tight disk quotas.

I am using PIL and numpy
# something hat at least looks sorta like
import numpy
import PIL
myImage = Image.open("C:\\file.bmp")
myImage.assarray(stuff)
I can't remember the code and am at work, but this will give you a big
array to work with. Each pixel for RGB looks kind of like [100,150,250]
then each line is in a matrix etc. It's a bit of a pain traversing the
matrices, but you can do anything you would do to an array. Pyro
Robotics also has a small tutorial about this.

PIL should be usable but I think there is also a Pyton wrapper for ImageMagick and I think it has some colour management type functions exposed too. Never tried any of this kind of thing though so I can't recommend anything with certainty. Alan G ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
[Tutor] Image Analysis
I have thought up a project for myself that is rather beyond my current knowledge, but I think it will be fun and very informative. I'll leave out the details right now, but the task that will be the hardest is that I need some way to analyze an image for color patterns. I would like to be able to load an image file of some format, and be able to determine what color the pixels are, in short. From this, I need to generate statistics, such as what color is most common, find patterns in the image, etc. If anyone knows ANYTHING about this sort of analysis in Python, or even any helpful tutorials on image analysis that are more general, I would greatly appreciate it. My only lead right now is PIL, and I am not sure if it will meet my needs. Thanks, Sam ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
