Re: OCR Divide By Zero Exception

Hi Walter, any progress from your Delphi developer on resolving this issue? I need to get OCR working in my Delphi app so it can be released this month.

Thanks,

Re: OCR Divide By Zero Exception

Hi Walter, 1. Do these documents always reproduce this behaviour, or is it sporadic? [It is consistent in Delphi at runtime with the files I supplied.] 2.

The Delphi EZeroDivide exception comes from ocrtool.dll when the OCR_MakeSearchable command is executed. Can you ...
