[Bug-ocrad] Ocrad-0.15 bug report

[richard spal]

Hello,

You may find the first page of the pdf file identified
below to provide a useful test case for improving the
accuracy of GNU Ocrad version 0.15. Ocrad made the
following errors reading this page (after conversion
to pnm):

correct         substituted     number of
letter(s)       symbol(s)       instances
---------       -----------     ---------
g               &               29
c               G               3
M               W               1
r               y               3
L               _               1
ffi             R*              1

I invoked Ocrad without specifying any options, after
converting the pdf file to pnm as follows:
gs -sPAPERSIZE=a4 -sDEVICE=pnmraw -r600 -dNOPAUSE
-dBATCH -sOutputFile=<filnam>.pnm -dLastPage=1 -q
<filnam>.pdf

The pdf file is a preprint entitled "Optimality
conditions and duality theory for minimizing sums of
the largest eigenvalues of symmetric matrices" by M.
L. Overton and R. S. Womersley, which can be
downloaded from
