NAME

       cthumb - a themable web picture album generator

SYNOPSIS

       cthumb -c [options] imagefile ... > file.album

       cthumb [options] file.album

DESCRIPTION

       Cthumb  creates  themable  web  picture  albums  with  thumbnails  of all the pictures, comments for each
       picture, etc.  Cthumb allows you to create web picture albums, i.e. collections of digital pictures, with
       small  thumbnails of your pictures and with captions. In addition, it allows you to have several views of
       the collection of pictures. An album is composed of a series of pages, each composed of a  collection  of
       pictures.  For  each  album  page may optionally have two or more versions, like for instance in English,
       Spanish, German, French, etc. So your visitors would go into the English version of the web  album,  into
       the Spanish version, etc.

       Typically  (this  is  what  I  use  it  for and why I wrote the program), you accumulate lots and lots of
       digital pictures and you need to label them and sort them out. Perhaps also you have friends  and  family
       that  speak  different languages. This program lets you very easily make picture albums and have the same
       pictures labelled in one or more languages.

       You can customize almost everything in the way the albums look on  the  screen,  from  the  size  of  the
       thumbnails  to  the background and foreground colors, the border colors, whether you want film-strips and
       their picture, etc.

OPERATION

       Cthumb has two modes of operation. The first one, which is active when option -c is specified, prints  an
       album  file,  via  stdout,  comprising all the images given as arguments to the command line. This is the
       first thing you need to do if you have never tried this program before, just to get you started. Once you
       have an album file, you edit it and put comments to the pictures, titles to the album pages, etc. In this
       mode, all the provided options in the command line will be passed through to the  album  file.   See  the
       format of the album file in section ALBUM FILES below.

       The second mode is the regular mode, the one that actually creates web pages, given the album file, so it
       is the one that does the real work of the script.  Given  an  album  file,  cthumb  generates  web  pages
       containing picture albums and an index with links to all the albums generated.

       Cthumb creates several HTML files, one per "Page" in the album.

       Check the README file (probably in /usr/doc/cthumb*/README) for more detailed info.

OPTIONS

       -c <files>  Create an album file with the files listed and spit it out in stadard out.

       -l <n>      Do pages in <n> languages.

       -f <n>      Go into film mode (<n> thumbnails per row).

       -r          Force re-generation of all thumbnails (slow).

       -x <n>      Make thumbnail width <n>.

       -y <n>      Make thumbnail height <n>.

       -n          In film mode, don't generate the strips.

       -m          Don't generate a main index file.

       -k          Generate text captions under the thumbnails.

       -t          Check the thumbnail width/height from the thumbnail image itself. This is slow.

       -b          Put the bytes of the main picture in the caption.

FILES

       By default cthumb creates the following files (foo being the name of the album file):

       foo-index.html  The table of contents.

ALBUM FILES

       Album files have a simple, textual format. First, comments in the file are started by the # character and
       last to the end of the line. The best way to find out the format is to use  the  -c  <files>  option  for
       album creation mode, which outputs an album file in stdout.

PER-USER VARIABLES

       cthumb  allows users to have their own variable settings in $HOME/.cthumbrc which is read and interpreted
       by perl. If perl cannot parse the file, cthumb will complain rather dryly that there is a parse error  in
       the file.

       This is cthumb version 4.2.

BUGS

       Option -r regenerates all thumbnails as the program sees them, i.e.  one per language. If  a  picture  is
       listed  twice  in  the  album,  it  will  be  generated  double the amount of times. If you have a lot of
       thumbnails, this can get lengthy. A workaround is to delete the thumbnails you want re-generated and  run
       cthumb without the -r option.
