2002.04.19 11:10 "fax2tiff problems...", by Siro Martello


I have been doing some work with the libtiff tool 'fax2tiff'. After having resolved a few problems to make it run on Windows, I have tested it using the g3test.g3 file from the provided pics folder. The pics folder contains a g3test.tif image that was generated with fax2tiff. I haven't been able to do the same using fax2tiff for g3test.g3 and I have received error messages saying "Line mismatch at scanline...(got...expected...)" and also "Premature EOL at scanline...(got...expected...)". Why did this happen? I was expecting fax2tiff to work OK with the file g3test.g3 as there is proof that it has worked with somebody else. All I get is a file with some garbage black and white pixels.

This worries me as I am in the process of writing a plugin reader for image data that contains CCITT G4 compressed data. I have tried to modify fax2tiff to read the raw G4 data with the hope I would have obtained a tiff image but again I obtained the same error messages as I did with g3test.g3 and no data were written into the tif file.

Thanks for any suggestion/help to solve the problem.

Best regards.
