Writing a "Raw" Image to a File (Win, PIL)

[W. eWatson]

I have an image of described as:
Img Info: {}
size: (640, 480)
format: None
mode: P
palette: <ImagePalette.ImagePalette instance at 0x02393378>
bands: ('P',)
type: <type 'instance'>

I'd like to write it to a file. Apparently, I need to convert it to a string
first. How do I do that? Pickle?

Did you bother reading the PIL documentation just for about 30seconds?

Hint: look for "save".

So, you are telling me what? To save it as a jpg file, or maybe a bmp file?
All of them have headers, right?

Have you tried the .tostring() method?

Perfect. Works exactly like I had hoped, 640x480 bytes--nothing more.
Thanks. I had noticed it, but didn't get the connection. Then I wandered
around nearby in the PIL description, and noticed something about decoding
and write. Unknown territory to me. However, if I had followed up there was
a connection between tostring and "raw" decoding.

Yes. Where exactly do you say "I don't want headers, I want raw data
dumped to the disk"?

Erm, in the Subject line?

Darn. Should consider reading them.
