When I try to use TIFFDataWidth, I get this compiler error:

Redstone[382] pushkar$ gcc -g -o main rgbtolhs-serial.c ip/rgblhs.c
tiff/tiff_misc.c -Iip/ -Ierrs/ -Itiff/ -ltiff -lm
/tmp/ccpBNPef.o(.text+0x349): In function `writeTIFFTags':
/rstc/user1/erc/pushkar/data-fusion/tiff/tiff_misc.c:86: undefined reference
to `TIFFDataWidth'
collect2: ld returned 1 exit status

I'm using 3.6.0 BETA2 libtiff. Was this available only after this version?

I've another question too, I'm calculating the bitspersample tag from sampleformat tag, will this always give the correct result: (dType is TIFFDataType) (wtags is just a struct containing all the tags I want).

  wtags.sampleFormat = dType;
  wtags.bitsPerSample = TIFFDataWidth(dType)*8;

Thanks,
