Divide image into 6 parts

Hi, I have an image which has a certain height n pixels. I would like to divide this to 6 parts so that each part has a height of n/6 pixels. The length will be the same for each. How would I be able to achieve this? Currently I have the Python Imaging Library imported, then have the ff:



for example, if somepic.bmp has a height of 270 pixels, then it will be divided into 6 images each with a height of 45 pixels.

I've never used PIL. I suppose your project is possible as stated. Anyway, install imagemagick, bash, and gawk if you haven't already got them. Write the following shell script into the file windowBlinds.sh , change the mode to executable, then run with the command

path/windowBlinds.sh NameOfPicture.picture_type

For example, I tested using the Bourne again shell command:

./windowBlinds.sh BrideAndGroom.jpg | bash

it made the pictures, correctly, as
0BrideAndGroom.jpg
1BrideAndGroom.jpg
2BrideAndGroom.jpg
3BrideAndGroom.jpg
4BrideAndGroom.jpg
5BrideAndGroom.jpg



Imagemagick handles a great many picture formats. I've written the code to give output in the same picture format as input---because it's easier and you didn't give other instructions. convert uses an internal form so can input one picture format and output another without trouble.

[Edit: this solution reloads the picture 6 times. If you need to do this in real time or if performance is an issue for whatever reason, a gimp script or the PIL might be preferable. Actually, imagemagick features a language as well so you could probably do it using the magickwand.]
