Hello,
I want to read a BMP file, do some processing and then write it in a
new file. The problem is in the third step. For reading the file, i
have converted the file into decimal numbers, representing the pixel
values. Then i perform calculations on those decimal numbers. Now i am
unable to convert those into the format as required by the "bmp" file.
Any one, who is into image reading/manipulation, please help.

Here is a link to a *very* crude BMP file utility I wrote a long time
ago. (http://www.geocities.com/ptmcg/python/index.html#bmp) Follow
the highlighted "module" link to see the underlying code - there are
methods for saving the BMP data to a file. Perhaps those samples
might give you some insight on what is required.

(I would probably rewrite this to use the struct module nowadays, but
this code works as is.)
