Albumtogo pictures from Linux

A couple of people have asked me where to find these- look for imgvtopgm which converts both ways. For instance here.

Scripts etc are provided as is, with no warranty of any kind, express or implied. Use at your own risk.

You need the pbmplus package.

First a script to view Album2go images:

function viewalbum () { strings $1 | head -1 && rawtopgm -headerskip 154 80 160 $1 | pnminvert| pnmscale -xscale 2  | pnmtoxwd | xwud ;  }

#!/bin/bash
# Take an image file #1 and convert it to a prc file #2 for Albumtogo
# Title of the file is #3 if given, otherwise it's derived from the filename
# Defaults to cropping the top left corner
# If there's an inital -f parameter it fits the image 
if [ "$1" = "-f" ]; then fit="t"; shift; fi 
if [ "$1" = "-i" ]; then install="t"; shift; fi 
file="$1"; out="$2"; 
if [ ! -f "$file" ]; then echo "Can't find $file"; exit 1; fi
if [ -z "$out" ]; then out=${file%.*}.prc; fi 

if [ -z "$3" ]; then 
  fileroot="${file##*/}"; fileroot="${fileroot%%.*}";
else
  fileroot="$3";
fi

  initial=anytopnm; 
  if [ ${file%jpg} != "${file}" ]; then initial=djpeg; fi;
  $initial $file |  ppmtopgm > /tmp/album.pgm &&
if [ -n "$fit" ]; then 
  scale=`pnmfile /tmp/album.pgm  | awk '{ if ($4 > $6) print "-xsize"; else print "-ysize"; }'` &&
pnmscale $scale 160 /tmp/album.pgm> /tmp/album1.pgm 
else 
  scale=`pnmfile /tmp/album.pgm  | awk '{ if ($4 < $6) print "-xsize"; else print "-ysize"; }'` &&
pnmscale $scale 160 /tmp/album.pgm| pnmcut 0 0 160 160 > /tmp/album1.pgm 
fi 
echo -n "$fileroot"> ${out} && len=${#fileroot}
tail -c +$[ $len + 1 ]   $HOME/various/header.prc >> ${out} && 
pnmpaste -replace  /tmp/album1.pgm  0 0 $HOME/various/icons/black.pgm| pnminvert | pnmdepth 15 |tail +4 | ~/bin/packnibbles>> ${out} 
if [ $? ]; then 
  echo "Something went wrong"; 
  exit 1
fi
if [ -n "$install" ]; then 
  echo "Queuing $out for installation on palm"
  gpilot-install-file -l ${out} ; 
  rm ${out}; 
fi 
rm -f /tmp/album*.pgm;

Compile with gcc packnibbles.C -o packnibbles

#include 
/* gcc packnibbles.c -o ../packnibbles
 */
main ()
{
  while(!feof(stdin))
    {
      unsigned char c,c2;
      c=getchar(); c2=getchar();
      putchar((c&0xf)<<4|(c2&0xf));
    }
  exit(0);
}

ppmmake black 160 160 | ppmtopgm > black.pgm
