Good News! (for some, anyway :-) I have been toying with LibTIFF for a long time, but three days ago I took a serious look at the problems in generating LZW compressed pictures and other possible obstructions. My boss i paying me to do so, and then we though we would let YOU be beta-testers if you would like. The following changes has been made to the library: o Errors and Warnings are reported in MessageBoxes - not via fprintf. o TiffPrintDirectory is not available (right now) because it uses fprintf. o Rationals were written as obnoxiously large fractions. They are not reduced before being written to file. o Ability to write both II and MM type tiff images. Yes that's right you can write little and big endian images using the library. I have the sources here, but would like them to be tested out before merging them with the original libtiff library. The last two changes would be nice to have in the original library as well. BUT: where can I put these files for the public? Please note that the compilation was done using Microsoft C/C++ 8.0 (Visual) and the makefile included (makefile.win) generates a libtiffw.lib suitable for linking into a Windows DLL. It is not itself a DLL. For those of you who have tries WINTIFF6.ZIP, we found that this library is a little bit faster (possibly because it is linked directly into the DLL and not called as a DLL) except for LZW compression which is approx. 40% faster. I you are interested in testing this piece of software, please let me know. I get a lot of crap mail from a mailing list that I can't seem to get my name deleted from. Please mention LIBTIFFW or LIBTIFF.DLL or something similar in the subject of the letter. If not, you'll risk that the letter goes to /dev/nul before I read it. /Soren -- Soren Pingel Dalsgaard pingel@daimi.aau.dk Department of Computer Science Aarhus University Ny Munkegade 116 DK-8000 Aarhus C DENMARK
