Hi, 

I am using libtiff version 3.7.2 and test images from
ftp://ftp.remotesensing.org/pub/libtiff/pics-3.8.0.tar.gz on windows
platform. 

When I try to read an LZW compressed image(oxford.tif from the test image
set) using TIFFReadRGBAImage function,  I get error "requested compression
is not  configured". However, in TiffConf.h  there is  a macro defined for
LZW support and a query on Compression Tag field returns LZW type
compression. How can I configure LZW compression and be able to read LZW and
other compressed type files ? With libtiff version I am using I can only
read tiff files with no compression. 

Thanks.
