Mogrify uncompressed tiff to compressed Lzw Tiff - Issues

[ewanw]

Version: ImageMagick 6.9.3-3 Q8 x86_64 2016-02-11[/color]
OS: Debian 8.3

I am having an issue when i try to mogrify or convert an uncompressed tiff to a compressed LZW tiff using the following cmd:-

Code: Select all

mogrify  -compress LZW 000001-5.tif

or

Code: Select all

convert  000001.tif -compress LZW 00001-3.tif

The resulting image just looks like the static you get on the tv when no station tuned.
Has anyone else come across this issue?
Any help on this is appreciated.

Hi
I have Version: ImageMagick 6.9.1-10 Q8 x64 2015-07-25 on windows 8.1 and it works fine but when i install the same version on ubuntu or debian i get the issue described above.

Maybe this is a libtiff issue? Which version are you using, and can you upgrade it to the latest?
