I have a PNG image, and wondering how to efficiently convert it to PBM in python

Question

Is there any simple way for converting PNG to PBM?

ocrad requires PBM image, not PNG.

Check out Pillow. According to the docs, it supports PBM, PGM, and PPM formats out of the box. The following code should get you started:

from PIL import Image

im = Image.open("myfile.png")
im.save("myfile.pbm")

On my 1001pxd used as a router it works perfectly, although on OS X 10.9.5 `sudo easy_install PIL` returns: https://gist.github.com/ArchieT/ceceb64a43b5d268dde2 – Mika Feiler Nov 20 '14 at 18:36
@ArchieT install using `pip`. Also, the package name is `pillow`, not `PIL`. Pillow is a fork of PIL, massively and continuously updated. `PIL` is ancient. – MattDMo Nov 20 '14 at 18:37
`gietwenti:~ mf$ sudo pip install PIL --allow-external PIL Downloading/unpacking PIL Could not find any downloads that satisfy the requirement PIL Some insecure and unverifiable files were ignored (use --allow-unverified PIL to allow). Cleaning up... No distributions at all found for PIL Storing debug log for failure in /Users/mf/.pip/pip.logz` Installing pillow using pip theoretically worked, but I cannot import it. And installing pillow using easy_install: [my gist link above] – Mika Feiler Nov 20 '14 at 18:46
I've read the documentation from your link; `sudo easy_install Pillow` — worked. And they wrote to not to use pip as it doesn't support Python Eggs. Anyway, thanks for a great and fast answer! – Mika Feiler Nov 20 '14 at 18:55
