I have a 640x480 b/w bmp image file that can be converted to a dat file. I would like
to convert the value of each pixel that is below say 120 units to exactly 40 units.
I've never written a python program in my life. However, the manual for the image
application I'm looking at show the following line to create a mask.dat file of size
640x480 bytes with every value set to 40:
python -c "open('mask.dat','w').write(chr(40)*640*480)"
I suspect a program to do what I need is not much more complicated. Can someone
construct a program for me to do the job? It'll probably be the only python program I
ever need.
