I've got some photos I'd like to try ocropus on, but I don't know what
the effective DPI is.  The model seems to be quite DPI-sensitive.  Is
there any way to use ocropus to estimate the DPI of an image?  For
instance, I've got characters that are about 40 pixels high.  What DPI
is that?

Generally, OCRopus likes regular font sizes at 300dpi, so it should have
roughly the same number of pixels as a 12pt font at 300dpi.
