My script for resize and retouch all photo in a folder

monotiz · 2009-12-23 12:38:48

Hi,
I'm excuse for my english but I'm italian.

I've create a script that use mmv and ImageMagick for elaborate the photos in a folder and all subfolder. Actually all the folder and file can't have space in a name. Check this topic to rename the file and folder.

My script:
- remane all *.JPG in *r.jpg
- process all folder (eccept ${Not_Proc_Dir})
- adjust color, resize dimension and reduce the JPEG quality for all file that not contain ${postfix} postfix.
- resize dimension and reduce the JPEG quality for all file that not contain ${prefix} prefix.
- ask you if original file must move in a ${move_folder} folder.

Any suggest and contribut are much appreciated.

About the only suggestion I would make is to have the script take arguments for some of the variables that would change. IE: $1 would be for "quality" $2 would be for "size" etc so you could run your script like

myscript 75 2880

make sense ? I'm always interested to see imagemagick scripts that manipulate images.

Several years ago, I wrote several shell scripts that do similar things to this.
http://sourceforge.net/projects/bbips/
I have all of them listed http://bashscripts.org/forum/viewforum.php?f=34 here as well.

my resize script looks like this:
WARNING - this script REPLACES your images so ALWAYS backup your original images ... yeah... i wrote a script for that too....

Oh what the heck, while we're at it, here's my script that simply takes a bunch of images and resizes them, makes thumbnails, and orders them sequentially. It's what I use whenever I post images to my blog.

function mkpics {
    fmt="jpg"
    imgsz="100%"
    tmbsz="15%"
    id=1

    while [ $# -gt 0 ] ; do
        case "$1" in
            -f)
                fmt=$2 ; shift 2 ;;
            -i)
                imgsz=$2 ; shift 2 ;;
            -t)
                tmbsz=$2 ; shift 2 ;;
            -n)
                id=$2 ; shift 2 ;;
            -s)
                sfx=$2 ; shift 2 ;;
            -p)
                pfx=$2 ; shift 2 ;;
            *)
                echo 'error: ' $1 $2
                shift 1 ;;
        esac
    done

    mkdir final

    ls *.* | while read img ; do
            echo "$img    -> $id.$fmt"
            
            convert $img -scale $imgsz final/$pfx$id$sfx.$fmt &
            convert $img -scale $tmbsz final/$pfx$id\_t$sfx.$fmt &
            
            id=$((id+1))
    done
}

Thanks for those scripts. I edited them a little and wrapped them as functions so i could put them in my .bashrc.

This is what i'm using to resize pictures now:

# resize a single picture
function pres () {
#no arguments, print usage
if [ $# = 0 ]
then
 echo "Usage: pres filename."
 echo "Example: pres P103845.JPG"
else
 echo "Resizing ${i:2} to 1920 x 1200 at 90% quality with filename res-$1";convert -resize 1920x1200 -quality 90 $1 res-$1
fi
}

# resize all pictures in a directory
function presa () { # usage: picresa width height quality
for i in $(find . -maxdepth 1 -type f \-iname "*.png" -o -iname "*.jpg" -o -iname "*.jpeg" -o -iname "*.bmp");
do
echo "Resizing ${i:2} to $1 x $2 at $3% quality";convert ${i:2} -quality $3 -resize $1\x$2 new_${i:2}; /bin/mv new_${i:2} ${i:2} ;
done
}

# resize one picture specifying quality, width and height
function press () {
#no arguments, print usage
if [ $# = 0 ]
then
 echo "Usage: presz width height quality filename."
 echo "Example: presz 1920 1200 90 P103845.JPG"
else
 echo "Resizing ${i:2} to $1 x $2 at $3% quality with filename ress-$4";convert -resize $1\x$2 -quality $3 $4 ress-$4
fi
}

# move pictures to dir "final", rename and create thumbnails
function prest {
    fmt="jpg"
    imgsz="100%"
    tmbsz="15%"
    id=1

    while [ $# -gt 0 ] ; do
        case "$1" in
            -f)
                fmt=$2 ; shift 2 ;;
            -i)
                imgsz=$2 ; shift 2 ;;
            -t)
                tmbsz=$2 ; shift 2 ;;
            -n)
                id=$2 ; shift 2 ;;
            -s)
                sfx=$2 ; shift 2 ;;
            -p)
                pfx=$2 ; shift 2 ;;
            *)
                echo 'error: ' $1 $2
                shift 1 ;;
        esac
    done

    mkdir final

    ls *.* | while read img ; do
            echo "$img    -> $id.$fmt"
            
            convert $img -scale $imgsz final/$pfx$id$sfx.$fmt &
            convert $img -scale $tmbsz final/$pfx$id\_t$sfx.$fmt &
            
            id=$((id+1))
    done
}

I also tried some packages from the aur to resize pictures and found sir to be the best (only tested gtk apps).
