The thumbnail was regenerated in spite of me having put a thumb nail file on the card. yes. the script mentioned above works perfectly for me. you can adapt it to generate thumbnails for images by changing lines 10-13 and 26 appropriately. find an updated version here: http://konrad.familie-kieling.de/code/t2b Jellby 01-31-2008, 04:00 AM Why not use this line instead?: 'convert -resize 96x144 -dither -map \"$palette\" \"$file\" PNM:- | pnmtopng 2>/dev/null |' It seems to work just as well, and it uses one less command (djpeg) and allows for filenames with spaces. What I could not find is the way to generate the correct kind of PNG file directly with convert, without the need for pnmtopng. |
