Thanks for the explanation, Quan. I had just stumbled upon the post that you noted. If you do have success in future, please let me know. I have other ways of scanning, but the integrated approach would be handy. I'll keep following this thread in case you are successful. Just for the record... Your VietOCR app is fantastic. I'm doing a volunteer project to transcribe some World War 1 typewritten documents. Tesseract was the only OCR engine that seemed to do a decent job. Without VietOCR, the complex...

Quan; A bit more info about the SANE installation on a Mac. The 'scanimage', 'sane-find-scanner' and 'sane-config' executables are installed in '/usr/local/bin' by Mattias' install packages. The directory '/usr/local/bin' is in the PATH.

Quan; Re: Scanning functionality The SAN packages were installed from precompiled binaries (http://www.ellert.se/twain-sane/) supplied by Mattias Ellert. So it gets istalled in the regular usr directory structure. I decided to use his installation package, as it has a preference pane configuration applet, which leaves less room for error. I'm getting the following NullPointerException. Not sure what the isuue might be. Any ideas for me to follow up? Last login: Wed Jan 27 07:47:59 on ttys001 Garys-MacBook-Pro:~...

SUCCESS!!!! That worked perfectly and I can now correct errors in the OCR'd text. There's only one function left for me to debug and get working. Could I ask if the scan function requires 32-bit or will it run with a 64-bit SANE install? Of course; I'll also check the symlinks to make sure they're OK as well.

Quan; This version gets further, but seems to have an issue. I've verified that 'libhunspell.dylib' is present as a symlink in '/opt/local/lib' and points to '/opt/local/lib/libhunspell-1.7.0.dylib'. I've checked that that 'hunspell' itself works from the command line. So I'm not quite sure what to make of the following console message. Is this due to VietOCR expecting hunspell to be 32-bit and finding a 64-bit library? (If so, this could also be the same issue that is haunting the scanner extension....

Thanks for following up on this. I just ran the new test-version, but got a different exception. Looks like it got further though. Not sure, but there could be a simple typo in the target library name in the code. Here is the console window output.
