Yes. The export file predates the scale factor in ocrad and was supposed
to contain coordinates relative to the input file, so that a frontend
program could locate characters, etc, on it.
When a scaling factor is specified, the scaled image replaces the input
image inside ocrad, and the exported coordinates wouldn't correspond to
the input file anymore.
Of course this behaviour may be changed, perhaps adding a "scale" line
to the export file, if nobody finds a reason not to. Meanwhile you can
remove the offending test from main.cc, or copy the scaled file and use
ocrad on the copy:
`ocrad -s2 -C -o file2.pbm file.pbm'
`ocrad -x file2.orf file2.pbm'

Antonio.
