# Convert all JPG/BMP/GIF files in a folder to PNG format
#  and create Latex Bounding boxes if MikTex (or more specifically)
#  xbb.exe is installed
#
# Modified Giovanni (giovanni@reflections.co.nz)
#
# Based on a the JPG2PNG.py script found at
#    http://www.akehrer.com/wiki/code:jpg2png
#
# Modified to do a bulk conversion of all JPG/BMP/GIF files in a
# folder to PNG format.
#
# Note: No colour profile information is embedded (yet)

#=================================================================
# You may need to install the Python Imaging Library
# from
#      http://www.pythonware.com/products/pil/
#=================================================================
# Just run the script - converts all files in the current folder
#
# if you don't want the xbb files, just delete/comment out the last line
