#! /bin/sh # 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 # (4) portable portable portable # There are many programs that violate 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. ## No cycles in the call graph or you'll lose. ## 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 variables are prefixed with "RETURN_". Command line options ## are prefixed with "ARGV_". Defaults are prefixed with "DEFAULT_", ## and globals are prefixed with "GLOBAL_". ## GLOBAL_ will hold all the settings that we should act on. These came ## either from a DEFAULT_ or an ARGV_ if the user overrode the DEFAULT_. ## This script used to have no functions at all, but I found that annoying ## to maintain, so now I've embraced function-mania. main () { init_defaults read_dotrc_file find_needed make_dir_transversible "." parse_args $* get_image_list point_stdout_to_index_file [ $GLOBAL_print_html_header_footer -eq 1 ] && print_html_header print_html_table_start iterate_over_image_list print_html_table_end [ $GLOBAL_print_html_header_footer -eq 1 ] && print_html_footer [ $GLOBAL_create_slideshow -eq 1 ] && create_slideshow exit 0 } create_slideshow () { [ $GLOBAL_create_slideshow -eq 0 ] && return remove_existing_slideshow_html_files create_slideshow_image_list while read fileset do prev=`echo "$fileset" | cut -d\| -f1` cur=`echo "$fileset" | cut -d\| -f2` next=`echo "$fileset" | cut -d\| -f3` create_slideshow_source_file "$prev" "$cur" "$next" if [ $GLOBAL_reduce_big_pics -eq 1 -a $GLOBAL_remove_originals -ne 1 ] then create_slideshow_reduced_file "$prev" "$cur" "$next" fi done < $GLOBAL_slideshow_image_list } create_slideshow_source_file () { cssf_prev_image="$1" cssf_cur_image="$2" cssf_next_image="$3" image_name_to_html_name "$cssf_cur_image" cssf_html_file="$RETURN_html_name" add_cleanup "$cssf_html_file" print_slideshow_file_header "$cssf_cur_image" "$cssf_html_file" print_slideshow_top_navlinks "$cssf_prev_image" "$cssf_cur_image" \ "$cssf_next_image" "source" "$cssf_html_file" print_slideshow_image "$cssf_cur_image" "$cssf_html_file" "source" print_slideshow_bottom_navlinks "$cssf_prev_image" "$cssf_cur_image" \ "$cssf_next_image" "source" "$cssf_html_file" print_slideshow_file_footer "$cssf_html_file" remove_cleanup "$cssf_html_file" } create_slideshow_reduced_file () { cssf_prev_image="$1" cssf_cur_image="$2" cssf_next_image="$3" cssf_cur_source_image="$cssf_cur_image" cssf_cur_reduced_image="$cssf_cur_image" if [ "$cssf_prev_image" != NULL ] then source_name_to_reduced_name "$cssf_prev_image" cssf_prev_image="$RETURN_reduced_name" fi source_name_to_reduced_name "$cssf_cur_image" cssf_cur_reduced_image="$RETURN_reduced_name" if [ -f "$RETURN_reduced_name" ] then cssf_cur_image="$RETURN_reduced_name" fi if [ "$cssf_next_image" != NULL ] then source_name_to_reduced_name "$cssf_next_image" cssf_next_image="$RETURN_reduced_name" fi image_name_to_html_name "$cssf_cur_reduced_image" cssf_html_file="$RETURN_html_name" add_cleanup "$cssf_html_file" print_slideshow_file_header "$cssf_cur_image" "$cssf_html_file" print_slideshow_top_navlinks "$cssf_prev_image" "$cssf_cur_image" \ "$cssf_next_image" "reduced" "$cssf_html_file" print_slideshow_image "$cssf_cur_image" "$cssf_html_file" "reduced" print_slideshow_bottom_navlinks "$cssf_prev_image" "$cssf_cur_image" \ "$cssf_next_image" "reduced" "$cssf_html_file" print_slideshow_file_footer "$cssf_html_file" remove_cleanup "$cssf_html_file" } print_slideshow_file_header () { psfh_image_file="$1" psfh_html_file="$2" get_file_english_name "$psfh_image_file" psfh_english_name="$RETURN_english_name" # The following exec goop so I don't have to manually redirect every # message to stderr in this function. exec 4>&1 # save stdout fd to fd #4 exec > "$psfh_html_file" # redirect stdout to stderr echo '' echo '' echo '' echo " $psfh_english_name" [ -n "$GLOBAL_meta_tag" ] && echo "$GLOBAL_meta_tag" if [ "$GLOBAL_html_charset" != "undef" ] then echo " " fi echo ' ' echo '' echo "$GLOBAL_body_tag" echo '' echo "" exec 1>&4 # Copy stdout fd back from temporary save fd, #4 make_file_readable "$psfh_html_file" } print_slideshow_file_footer () { psff_html_file="$1" echo '' >> "$psff_html_file" echo "" >> "$psff_html_file" echo "" >> "$psff_html_file" } print_slideshow_image () { psi_cur_image="$1" psi_html_file="$2" psi_type="$3" psi_target_pre="" psi_target_post="" if [ $psi_type = source ] then source_name_to_reduced_name "$psi_cur_image" if [ -f "$RETURN_reduced_name" ] then image_name_to_html_name "$RETURN_reduced_name" psi_target_pre="" psi_target_post="" fi else is_reduced_name "$psi_cur_image" if [ "$RETURN_is_reduced_name" -eq 1 ] then reduced_name_to_source_name "$psi_cur_image" if [ -f "$RETURN_source_name" ] then image_name_to_html_name "$RETURN_source_name" psi_target_pre="" psi_target_post="" fi fi fi get_dimensions "$psi_cur_image" echo "" >> "$psi_html_file" echo "

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 index.html. If an index.html is already present, its HTML is sent to stdout. 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. You need to use the program's internal variable names here. For instance, if you always want --use-two-windows mode, the internal name is $GLOBAL_use_two_windows so you'd need to set use_two_windows=1 in your .makethumbsrc. Most usefully, you can specify what kind of tag you want used in your web page with a setting like body_tag= Determining the variable names for the .makethumbsrc is not very user friendly, but I suspect this feature will not be widely used. If I'm wrong, I'll see about making it a little more user friendly. This script written by Jason Molenda, makethumbs(AT)molenda.com. This is version '$Revision: 1.67 $'.
