How do I resize a partition on an img file?

I have a puppy linux img that is 8gb but I need it to fit on a 6gb drive. How do I resize the ext2 partition on the img?

• partition
• disk-image
• puppy-linux

NOTE Make a backup, anything can go wrong ... I ran all those as root :

1. bind a loop device to the image: losetup /dev/loop10 $image_file
2. refresh partitions: partprobe /dev/loop10
3. adjust partition size: gparted /dev/loop10
4. undo the loop: losetup -d /dev/loop10
5. remove unwanted space: truncate -s -${SIZE}G $image_file (you might want to calculate the exact size based on values from fdisk/cfdisk * sector size)

NOTE You might need to double check the partitions' UUIDs, mine seem to have changed and I had to update fstab
