Hi,
I am new to scheme scripting.
What i want to do is open pictures from a directory and apply a very
simple macro.
I can do it manually with the following steps :
- open image the_image.jpg.
- save as the_image_with_thumbnail.jpg
- choose options : q = 0.85 , progressive, and default other options.
- check the option : save thumbnail.
- Click OK.
- close image.
Using a bash script or DOS batch file with imagemagick is a better and easier
solution.
Below is a bash script that I use to create thumbnails of photos from my
digital camera.
You can pass the jpg quality parameter to convert - I used the default which
is 75% I think. The options are in the docs.

#!/bin/bash
echo Converting ...
if [ ! -d resized-1024x768 ]
then
mkdir resized-1024x768
fi
if [ ! -d resized-256x192 ]
then
mkdir resized-256x192
fi
# Loop through all jpg files in current folder
#
for i in *.jpg
do
FileName_Stripped=`echo $i | cut -d. -f1`
if [ ! -e resized-1024x768/$FileName_Stripped-1024x768.jpg ]
then
echo Converting $i to $FileName_Stripped-1024x768.jpg
convert -resize 1024x768
$i resized-1024x768/$FileName_Stripped-1024x768.jpg
fi
if [ ! -e resized-256x192/$FileName_Stripped-256x192.jpg ]
then
echo Converting $i to $FileName_Stripped-256x192.jpg
convert -resize 256x192
$i resized-256x192/$FileName_Stripped-256x192.jpg
fi
done
echo Done

Thank you very much for pointing this tool to me.
However ...
I can't find in imagemagick the ability to save thumbnail as EXIF data
in the jpeg, and not in a different picture.
Ok, so if someone want to write Exif thumbnail to jpeg i've done this
with imagemagik and exiftools to write thumbnail generated by imagemagik...
Maybe there's a better way to do this but this tools works just as
expected and there's no loss of other exif info.
But if someone ever got a scheme script to do that through GIMP ... i'am
interested
Thanks list !
