[Gimp-user] convert tiff image to bitonal

[Alexandru Cabuz]

Imagemagick does the job.

Command I used was this:

convert -colors 2 -density 600x600 -colorspace gray -compress group4
pg_0015.pdf pg_0015.tif

The tif files generated are bitonal and the djvulibre bitonal
algorithm cjb2 works fine on them.

Was not able to batch, so I used openoffice spreadsheet to generate a
script containing 774 lines for the 774 images I had to convert. :-)
