( #3333=superdoc: print w/ replies, xml ) Need Help??
@Anonymous Monk, thanks a lot for the guidance. I tested the modified code with a MDI file that already has OCR information like so:
$miDoc->Create('OCR-test-result.mdi'); my $OCRresult = $miDoc->{Images}->Item(0)->{Layout}{Text}; print $OCRresult;
It outputs the expected result. But if I retain the OCR method like the original code did:
$miDoc->Create('OCR-test.tif'); $miDoc->OCR(LangId =>'miLANG_ENGLISH'); my $OCRresult = $miDoc->{Images}->Item(0)->{Layout}{Text}; print $OCRresult;
Perl throws me the same error message: Use of uninitialized value $OCRresult in print

So now it looks like there's also something wrong with this line:

$miDoc->OCR(LangId =>'miLANG_ENGLISH');
What diagnostic method can I use to solve the problem. The following code gives me nothing:
eval {$miDoc->OCR(LangId =>'miLANG_ENGLISH')}; warn $@ if $@;
Thanks again :)
