write a bitmap using python

[lyuan]

Hi,
How can I write a bitmap using python? I have some integer data and
want to generate a bitmap graph for visualization. Any suggestion will
be appreciated.
Sorry if this is an FAQ, BTW, where can I find the FAQ of this list?

thanks

I chased this down last fall when I needed to visualize some data much as
you describe.

Follow the 'module' link to retrieve the bmp.py source.

The Python Image Library (PIL) is probably what you want:

If you application involves a UI like Qt/PyQt, then there are ample
classes to perform this operation (QPixmap, QImage, etc). Otherwise,
look at PIL.

Hi, Paul,
Thanks for your help. The code is indeed clear and illustrative.

I wonder under what license is your code distributed? Do you mind if I
include part of your code into my code? I'm not writing anything
commercial, but instead a scientific data analysis program.

Lihua -

Re-download the .py file - it now includes an MIT open source license
header.

I'm glad it could help.
