As far as we know, the only tif to cdx conversion that might be possible to achieve is actually import of TIFF graphics to CorelDRAW and then exporting the reused content as CDX compressed drawing. But this is not a straight up file conversion or just resaving of the content, because CorelDRAW is not a raster editor. In any case, there are not many choices that can save CDX format.
