I'm successfully converting single and multi-page tiff images with tiff2pdf using jpg compression. When I attempt with LZW compression, the resulting image is all black. My libtiff dependencies are all up to date.
Is there anything I need to do to configure support for LZW compression when using tiff2pdf?
