is there any partition tools which can dynamically increase partition's size without data loss?

my system is triple-booted , windows 7 on physical partition, openSUSE12.3 and mageia 3 on logic partitions.
windows 7's file system is NTFS
openSUSE12.3 and mageia 3 's file system is ext4
i wanna format mageia 3, and give its harddisk space to openSUSE12.3
in windows, partition magic can do this job. but it does not work in windows 7.
can parted magic do this job? or any other tools can do ?
thanks advance.
