# A short note from Eric Pop the developer of the "old" igal version:
# Note to do-it-yourselvers and Computer Science types: the IGAL code is
# UGLY. I'm am amateur programmer, not a CS type. If my scrappy code runs
# and gives the right results, I'm happy. If others find it useful, that's
# wonderful. I hope my comments can help decipher the mess below a bit. I
# wrote IGAL partly because I wanted another excuse to learn Perl (it's
# useful for my research too) and because other image gallery generators
# had hairy dependencies and didn't do what I needed. So... my apologies
# if the spaghetti below makes you cringe. It works for me, so I don't
# really have plans (or time) to clean it up.
#
############################################################################

This is iGal2 $VERSION an HTML image slide show generator.
Syntax: igal [-option -option ...]
Options: -a write image sizes under thumbnails on index page
-c first generate and then use captions
-C like -c, but preserve file names as captions
-d <dir> operate on files in directory <dir> (.)
-e write EXIF information under image (needs Image::ExifTool)
-f force thumbnail regeneration
-h displays this brief help; same as --help
-i <file> name of the main thumbnail index file (index.html)
-k use the image captions for the HTML slide titles
-m <file> Automatically add watermark to each image
-n use image file names for the HTML slide files
-p <n> cellpadding value of thumbnail index tables (3)
-r omit the film reel effect altogether
-s make no HTML slides, link thumbnails to images
-t <n> height of the film reel tiled image (21)
-u write captions under thumbnails on index page
-w <n> rows in thumbnail index are <n> images wide (5)
-x omit the image count from the captions
-y <n> scale all thumbnails to the same height <n> (75)
--ad like -a, but write only the image dimensions
--as like -a, but write only the file size (in kbytes)
--bigy <n> like -y, use it if you have very large image files
--con <> options to pass to convert or cjpeg (e.g. -quality N)
--help displays this brief help; same as -h
--www make all iGal files world-readable
--xy <n> scale thumbs to <n> pixels in their longer dimension
------------- N E W F U N C T I O N S --------------------------
--dest <dir> Destination directory for the helper files
(thumbnails, slides, etc.) igal generates. This is
relative to the operative directory -d and has to be
one level below (.)
--AddSubdir If igal finds further directories beneath your image
directory -d, it will generate HTML Links in the
index file (index.html) to this directories.
Default is (off). Directories given with --dest or
starting with a "." will be ignored.
Note: igal will not work recursively, it just adds
HTML links to the directories below.
-m <file> Automatically add watermark to each image - this
works well with a transparent .gif, but anything
can be used - edit the "composite" line later on
to adjust visibility/position of mark if required
Originals will be left with a .unmarked extension
-o <dir> Root URL of alternate location for the links to full
size images. Use this if your indexes will be in
a different location/server from the back end images
--pagination <n> Maximum number of images on one page.
If the given number of images is reached a new page
is started. Pagination number <n> should be a multiple
of parameter -w (default 5).
Default 0 - means no pagination at all.
Note: default values are given in parentheses (where applicable).

# Jan 13, 2003: i played around w/the various ways in which convert can
# resize images, i.e with -scale, -sample, -geometry (equivalent to -resize)
# and lo and behold, i realized that igal will run MUCH faster when resizing
# is done with -scale while quality is about same as with -geometry (in igal
# 1.3 and earlier). using -sample gives me a bit more speed advantage but
# is not worth using as the scaled-down output seems to be pretty poor.
# here are some timed-runs on a directory w/some images:
# * w/convert -sample (poor quality) 7.24 sec
# * w/convert -scale (ok quality) 9.14 sec
# * w/convert -resize (ok quality) 23.8 sec
# * w/cjpeg/djpeg (ok quality) 20.1 sec
# so from now on all convert -scale is used everywhere below because it seems
# to be the clear winner for quality vs speed.
# generate .thumbnails in the same directory with the original image files (or in the given --dest directory)
# if they don't exist already or if the -f switch is given
