Flipping images using ImageMagick

flipFlop.sh

# This isn't a script. Just copy / paste or type along.

# Go to your downloads directory
cd ~/Downloads

# Unzip the icon set and cd into the directory
unzip -q ic_attach_file_black_24dp.zip
cd ic_attach_file_black_24dp

# At this point you'll have some lovely attach
# icons where the open end of the paperclip is
# on the right

# Flip those images!
for IMAGE in $(find android -iname "*png") ; do convert $IMAGE -flop $IMAGE ; done

# And now the open end is on the left! However, the
# directories don't have the correct name so let's
# rename them. Bear with me, my script-fu is not
# Jedi-like.
cd android
for ANDROID_DIR in $(ls -d */) ; do mv $ANDROID_DIR ${ANDROID_DIR/drawable/drawable-ldrtl} ; done

# Now just merge them into your project.
