convert_image_to_eps.workflow

#convert tool to download http://www.imagemagick.org/script/convert.php
#Step 1 : In automator > New folder action : select the folder to watch 
#Step 2 (only for testing) : Add "Get elements from the folder indicated" -> select few images from different origins
#Step 3 : Add a shell script with the following code

for f in "$@"
do
	filename=$(basename "$f")
	base="${filename%.*}"
	newbase="${base//[^A-Za-z0-9_-]}"
	dest= "${/absolute/path/to/my/eps/folder}
	"/usr/local/bin/convert" "$f" "$dest/$newbase.eps"
done

#improvements: add a condition to check the file format you want to convert
