Creates a PDF file from image files
Tumble is a utility to construct PDF files from one or more image files. Supported input image file formats are JPEG, and black and white TIFF single- or multi-page. Black and white images will be encoded in the PDF output using lossless Group 4 fax compression ITU-T recommendation T.6. This provides a very good compression ratio for text and line art. JPEG images will be preserved with the original coding.
The current version of Tumble will only work on little-endian systems, such as x86, VAX, and Alpha. The byte order dependencies will be fixed in a later release.
