Well Corel Draw 1.2 will take bitmap files and convert them to 
object oriented files with their CorelTrace program. Then Corel
Draw itself will export the file to DXF format.

DXF files are object oriented. Group 3 FAX and PBM are bitmap formats.
There is more to it than just a conversion such as from tiff to group 3 or
whatever. First you have to decide which groups of dots make an object, then
you can write an object form of things. This is NO EASY TASK!
