Hello IM friends!

I've got this error-message "convert: CompressionNotSupported `JPEG'.", when i tried to convert a normal RGB-Tiff into a JPEG-compressen-Tif with the following command:

convert input.tif -depth 8 -compress JPEG -quality 100 output.tif

The only thing i want is to enable JPEG comression in Tif-file ... and it does not work unfortunatly...

In fact, this error-message only occures on the one linux server, where the most actual IM version is installed: "ImageMagick 6.4.3 Q16".
On my own WindowsXP system, with the same IM version, this error doesn't occur, but as i can see from the filesize there is also no JPEG compression

Has somebody similar experience? What could it be?

Thanks in advance!

Perhaps you don't have the JPG delegate library installed?

I have asked my colleage to rebuild imagemagick with all necessary libs, and the error didn't occure anymore.
