Hello, I used your module, and having a particular issue, I found out
some little details which were provoking warnings:
CHECK_PDF flag is on.. at /usr/local/share/perl/5.12.4/PDF/OCR2/Base.pm
line 40.
defined(%hash) is deprecated at
/usr/local/share/perl/5.12.4/PDF/Burst.pm line 311.
(Maybe you should just omit the defined()?)
CHECK_PDF flag is on.. at /usr/local/share/perl/5.12.4/PDF/OCR2/Base.pm
line 40.
Use of uninitialized value in concatenation (.) or string at
/usr/local/share/perl/5.12.4/PDF/OCR2/Page.pm line 100.
I made some little modifications.
In OCR2/Page.pm
at line 100 I replaced:
$txt .= $self->_text_from_images;
by
$txt .= $self->_text_from_images if ($self->_text_from_images);
In Burst.pm
At line 311 I replaced:
defined %dat or warn("had nothing in '$doc_dat'?") and return;
by
warn("had nothing in '$doc_dat'?"), return unless (%dat);
