Tumble converts one or more TIFF (B&W only) and
JPEG files into a PDF file. It was developed
primarily for use with scanned images. B&W images
will be encoded with Group 4 fax (T.6) lossless
compression. JPEG images are embedded as-is.
Tumble supports multi-page TIFF files, and can
generate PDF outline entries (bookmarks) based on
the file name and/or the page number.
