There are many different methods to make an image into black and white only. One method is:
Code: Select all
convert in.png -colorspace Gray -threshold 50% out.png

Please always provide your IM version and platform, since syntax may differ.

6.6.6 is very old (over 250 versions old). Don't you think it is time to upgrade?
