graphics/tumble 0.36p0 OpenBSD

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 1-bit 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 general command line syntax is:

tumble [options] <input>... -o <output.pdf>

The options in this mode are:

-v        verbose
-b <fmt>  create bookmarks

If the "-b" option is given, bookmarks will be created using the format string, which may contain arbitrary text and/or the following format specifiers:

%F  file name, sans suffix  e.g., "foo.tif" will just appear as "foo"
%p  page number of input file, useful for multipage TIFF files
