hi,
setup:
debian etch
T3 4.1.5
GM 1.1.6 from http://typo3.sunsite.dk/software/linux/
Image Processing within Typo3 works fine, my Problem:
I want to convert large lzw compressed tiff files to a lower resolution
and so i tried from shell:
'gm convert -geometry 800x600! <highres_tif_file_lzw_compressed>
<lowres_tif_file_lzw_compressed>'
But i just got this warning:
'/usr/local/graphicsmagick-1.1.6/bin/gm convert:
LZW compression is not available to due to Unisys patent enforcement.'
In the gm 1.1.6 README i found that the compilation already comes with
lzw compression support and i thaught the Unisys patent is expired since
2004?
So what's wrong here?
regards
thomas
