Resurrecting an old thread... For anyone looking to call b2d from Python...

First step was to build b2d on macOS (10.12.3) following nicola and mmphosis:
  gcc -DMINGW -arch i386 -Wno-pointer-sign -Wno-comment -o ../b2d b2d.c

The next crucial step is to resize your input images to be the correct size for HGR/DHGR etc. If you don't have the correct size then b2d will complain about "wrong format!".

Here, my Python code is reading an image from a URL (works just as well from a .jpg or .png file), resizing to be 280x192 (since I want HGR), saving it to a BMP, then calling b2d. Then I read in the bytes and do something with them.

from PIL import Image
import subprocess
img = Image.open(requests.get(url, stream=True).raw)
img = img.resize((280,192))
img.save('temp.bmp')
subprocess.check_call(['./b2d', 'temp.bmp', 'hgr'])
f = open("TEMPC.BIN", "rb")
data = f.read(8192)
f.close()

Hopefully this will help anyone else who is doing something similar.
Cheers,
Chris
