I don't know. Perhaps the LIBTIF library has a function to identify the TIF type of a file. Alternatively, I think the following free program would include such functionality:

Unfortunately, I got fatal execution errors. There were two tasks I tried. One was to use the free NirCmd.exe utility to create a .tif snapshot of a window and than try to get text from it. The other was to drop in your tesseract.exe for an older, minimalist one that I include with PDF2TXT. Here is more info on how to replicate what I was testing. NirCmd is available at NirCmd - Windows command line tool http://www.nirsoft.net/utils/nircmd.html The syntax is NirCmd.exe Save ScreenShotWin FileName.tif PDF2TXT is available at http://EmpowermentZone.com/p2tsetup.exe tesseract.exe is located by default in the directory C:\PDF2TXT\OCR In the PDF2TXT dialog, you can press Alt+F to check the Image Format checkbox, which then causes the program to attempt OCR rather than other text extraction methods. Let me know if you have more questions. I'm copying this message to the ProgrammingBlind list as well in case anyone thesere wants to try these tests.
