#!/bin/sh # # mkpg -- make a simple photo gallery # # This script uses a great little exif parser # named jname, available from http://www.sentex.net/~mwandel/jhead # # Canon MakerNote patch for jhead: # http://www.klake.eu.org/~jt/misc/jhead.diff # # File size conversion is done with ImageMagic's 'convert'. # # $Id: mkpg,v 3.7 2001/08/27 08:36:46 jt Exp $ # # HOWTO # # MAKE A GALLERY # # 1. Make a directory which contains all the pictures you want # include in your gallery. The script expects to see them in # JPEG format with Exif headers. # # $ mkdir gallery # # 2. Edit the file gallery/.mkpgrc (optional) - this file may # contain some variables used by the script, see below. # # 3. Edit the file gallery/.desc (optional). The format of this # file is as follows: # # file_name_1|This is a description for file_name_1|date_1 # file_name_2|This is a description for file_name_2|date_2 # ... # file_name_n|This is a description for file_name_n|date_n # # The date is useful only if your file doesn't contain the Exif # header. The description is optional - if it doesn't exist, the # script uses name of the file instead. # # 4. Make sure that the variables JHEAD CONVERT are set correctly # either in this file or in gallery/.mkpgrc # # 5. Run the command mkpg gallery # # ADD PICTURES # # You can more pictures to your gallery simply by copying the files # in your gallery directory. If you want to include description, edit # the file .desc. Then run the command "mkpg gallery". # # DELETE PICTURES # # 1. Delete Picture files in gallery directory, gallery/mids and # gallery/thumbs. # 2. Delete gallery/exif/file.exif (if exists) # 3. Remove the entry in dir/.desc (if exists) # 4. Run "mkpg path_to_gallery" # # CUSTOMIZE THE GALLERY # # Edit the variables in the file path_to_gallery/.mkpgrc or in this file and # Run "mkpg path_to_gallery". # VERSION=3.7 # # gallery/.mkpgrc can contain some variables, defaults are: # # Path to jhead program JHEAD=/home/jt/devel/html/pics/bin/jhead/jhead # Path to convert program CONVERT=/usr/X11R6/bin/convert # Background color for the HTML pages BGCOLOR=#ffffff # Middle size pictures are either small (512x384), medium (640x480) or # large (1024x768) MIDSIZE=small # The title of the gallery TITLE="Photo Gallery, mkpg version $VERSION" ####################################################################### # Check arguments ####################################################################### if [ -z "$1" ]; then echo "usage: $0 [dir] [title]" exit 1 fi if [ -n "$2" ]; then TITLE=$2 fi if [ -e $1/.desc ]; then DESC=jovain else DESC= echo "$0: Cannot find description file, using file names instead" fi if [ -e $1/.mkpgrc ]; then . $1/.mkpgrc fi if [ ! -e $1/thumbs ]; then mkdir $1/thumbs fi if [ ! -e $1/mids ]; then mkdir $1/mids fi if [ ! -e $1/exif ]; then mkdir $1/exif fi cd $1 ####################################################################### # Sort pictures ####################################################################### echo "$0: sorting" ( for PICS in *.jpg; do DATE=`$JHEAD $PICS | grep "^Date/Time" | awk -F": " '{print $2}' |\ sed 's/\(.*\):\(.*\):\(.*\) \(.*\):\(.*\):\(.*\)/\1\2\3\4\5\6/g'` if [ -z "$DATE" ]; then DATE=`date +%Y%m%d%H%M%S` fi echo $DATE:$PICS done ) | sort -n | awk -F":" '{print $2}' > .sorted DATE= if [ ! -s .sorted ]; then echo "$0: Found no .jpg files" exit 1 fi ####################################################################### # Write index ####################################################################### echo "$0: creating index.html" cat << EOF > index.html $TITLE
