Re: [Bug-ocrad] Best dpi

[Antonio Diaz]

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.
