Question

Acrobat 9 crashes on OCR

I've been trying to convert a batch of large PDF files to PDF searchable files by using the OCR of Acrobat. In the middle of a batch, a large (1000+ page) document crashes acrobat. I have narrowed it down to this image:

59,520 bytes

When I convert it to PDF (File->Create PDF->From Single File) and then use Acrobat to "Document->OCR Text Recognize->Recognize Text using OCR", Acrobat always crashes.

Is this true for anyone else that could try it?

It kills my batch processing and is making this large conversion quite painful. Is there a way around it?

The basic problem is that the png file is a 172 X 172 resolution. The minimum is 200dpi. I tried it in AA5 and it warned of an invalid resolution. I switched it to 2X the resolution. At that the OCR ran, but the only conversion was on the page number. I have no idea why AA9 would have crashed, but it is likely related to the page resolution.
