Hello André.
Thank you for your comments on Ocrad.
The best resolution for Ocrad is now, as you have already noted, 300 dpi.
Lower resolutions (150 dpi) tend to give characters too small. On the
other hand, the noise is a problem in higher resolutions (600 dpi).
Ocrad's algorithms are, just now, very simple. I hope they will be more
powerful on each new version.
Regards.

My question is: which is the best resolution to render the pbm images to
maximize the amount of text ocrad recognizes? I'm making tests with 300 dpi,
which give me files 2550x3300 and 600 dpi, which gives me files 5100x6600.
Currently the smaller files are giving me best results, hence my question.
