Thanks a lot Su. That is a very detailed explanation. I am going through the details. I will get back to you.

That is, you can't just create a default TIFF directory (out = TIFFOpen(sInputSinglePage.c_str(), "w");) and then write image data to that directory without first setting up the mandatory tags accordingly. Finally, you have to write the TIFF directory to the file. This is done by TIFFClose(). You should also close the input file at the end. Finally, the input image data are "Group3Fax" compressed. That means the function TIFFReadRawStrip() reads nonsense. You need to read with TIFFReadEncodedStrip(). You should read the TIFF documentation at: http://www.simplesystems.org/libtiff/index.html and get familiar with copying of data using as example: https://gitlab.com/libtiff/libtiff/-/blob/master/tools/tiffcp.c . I would suggest taking tiffcp.c in the debugger and debug how your file is copied there. Another example, how to write a simple TIFF image is given in https://gitlab.com/libtiff/libtiff/-/blob/master/test/custom_dir.c line 63 to 128.

Does this mean the TIFF internal data is Huge size for example 4GB or more. But the file Test.TIFF itself is just 370 KB. Hi LibTIFF team, Are there any other replies suggesting root-cause for this Test.TIFF error. Is the Test.TIFF is as per TIFF standard. Are there any other problems with this input TIFF or solution to successfully copy/write strips individually to TIFF files. Why is the size of single strip is returned as such a huge size(IS any field has wrong data). Will 64 bit of LibTIFF binaries will resolve this issue is some way. Regards, Ganesh.
