convert: CompressionNotSupported `JPEG'.

Post by mambojumbo »

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?
