TYPO3 Core

The images file size can be further decreased. I'm trying to push the fix for this to review.typo3.org.

Alright. Can you please document here what you did?
Maybe some settings you choose, in which tool, etc.
Thanks

I made a bash script that scans the TYPO3 core folder for PNG, JPEG and GIF files. The returned files are optimized by executing several image optimizer binaries.

Bash script:

folder=$1
if [ $folder ]
then
        folders=( $folder )
        for i in "${folders[@]}" 
        do
                # optimize png
                find $i -type f -iname '*.png' -exec sh -c "pngout {}; optipng -o7 {}; advpng -z1 {}; pngcrush -rem allb -brute -reduce {} {}.pngcrush && mv -f {}.pngcrush {}; chmod 777 {};" \;
                # optimize jpg
                find $i -type f -iname '*.jpg' -exec sh -c "/shopcvs/scripts/image_jpeg_optimizer_jpopt.sh {}; jpegoptim -p --strip-all -m88 {}; chmod 777 {};" \;
                # optimize jpeg
                find $i -type f -iname '*.jpeg' -exec sh -c "/shopcvs/scripts/image_jpeg_optimizer_jpopt.sh {}; jpegoptim -p --strip-all -m88 {}; chmod 777 {};" \;
                # optimize gif
                find $i -type f -iname '*.gif' -exec sh -c "gifsicle --batch -i {}; chmod 777 {};" \;
        done
else
        echo "/shopcvs/scripts/folder_img_optimizer.sh /folder" 
fi

And the contents of image_jpeg_optimizer_jpopt.sh:

siz() { ls -l "$1" | awk '{print $5}'; }

if type jhead >/dev/null 2>&1; then
    jhead=1 copy=none
else
    jhead=  copy=all
    echo >&2 WARNING: jhead not found, cannot optimize comments or EXIF data

Should we maybe put such scripts into some kind of "tool-package", for the case that new graphics are added to TYPO3?
There is afaik also the case that some SCSS are to be processed manually and then commited if they are updated. Do we maybe have some tools (and a doc on the process of updating) somewhere?
