# This script creates tumbnails, reduced versions of large images, and an
# index.html file pointing to all of it.
# Design goals are
# (1) exist in a single script that can be mailed around easily, etc.
# (2) generate clean, simple, portable HTML
# (3) no databases required
# (4) portable portable portable
# There are many other programs that compromise some or all of these goals.
# They are real neat, they make great web pages, they organize your life.
# They don't fit in a single ugly Bourne shell script whose only point in
# life is to take pictures off your digital camera and make them basically
# presentable to your friends.
# This script is in the public domain, share and enjoy.
# The latest version is always at http://www.molenda.com/makethumbs/
# Written by Jason Molenda, 1998-09-13; rewritten less lamely 2001-10-26.
## Guidelines for hacking:
##
## Start at main() and trace the function calls from there.
## Remember that there is no scoping of variables, so local variables aren't.
## You'll see some function-local variables with common names ("$fn" etc)
## prefixed with an abbreviation of the function name so that they don't
## overwrite a similarly named variable in the caller.
## As much as I like Bourne shell, I probably should have just done this
## in perl or python. On the down side, whichever of those I pick, I'll
## hear constant whining from about half of my friends. No one likes
## Bourne shell, so it's the safest language choice.
## Return values from functions are prefixed with "RETURN_".
## Command line options are prefixed with "ARGV_".
## Defaults are prefixed with "DEFAULT_"
## Settings from the .makethumbsrc are prefixed with "DOTRC_"
## Globals variables are prefixed with "GLOBAL_".
## GLOBAL_ will hold all the settings that we should act on. These came
## either from a DEFAULT_, ARGV_, or DOTRC_ if the user overrode the DEFAULT_.

--maxthumbsize Maximum size of thumbnails, in pixels, default $DEFAULT_max_thumb_size

--compact-index Create a compact index page to pack in lots of thumbnails
--disable-reduce Don't create a reduced img if the picture is large
--disable-slideshow Don't create slideshow files

--remove-originals Remove original images if we make reduced versions.
Useful when disk space is limited; default is `[ $DEFAULT_remove_originals -eq 1 ] && echo enabled || echo disabled`
WARNING!!! This option *will* remove your original images if
reduced images are available!
Run this script in a directory of JPEG files to create thumbnail images and
an ${GLOBAL_index_filename}. If an ${GLOBAL_index_filename} is already present, its HTML is sent to stdout.
Makethumbs will not overwrite files you've created by hand.
You may list the JPEG files on the command line if you prefer. By default,
`basename $0` works on every JPEG file in the current working directory.
You can permanently override options by creating a ~/.makethumbsrc file.
Many more features can be tweaked via the .makethumbsrc file. See the
documentation on the makethumbs home page for more information about this
file.
