I remember from my PIT investigation, there are no such things like block size and block count.
There is starting block and size (in blocks).
So, your application should adjust starting blocks. For example, if i edit size of partition, all following partitions should move accordingly. Starting block shouldn't be editable, but calculated.

Also, if you take blocks away from /system/, remember to add them to another partition, or you'll just be wasting blocks by not assigning them to any partition at all.

Thanks for that, I knew they had to match up somewhere.

EFS Backup
Just a friendly reminder to everyone that may attempt to flash a PIT file. BACK UP YOUR EFS FOLDER. Repartitioning your phone's memory can wipe the EFS partition and render you without carrier coverage, generic IMEI and lot's of headaches. I commend the work done to put together PIT Magic though! Flippin' sweet!

be very careful with this...

I wondered what the extra 256 bytes after the partition entries in the S3 pit file were for. PIT Magic will simply write a pit file for S3 without those 256 bytes at the end which will essentially be an unsigned pit file in that case.

Right, but won't breaking the signature cause undesired effects?

When saving an S3 pit file in PIT Magic, the extra 256 bytes at the end wont be written therefore no signature.

My theory is the signature is to verify the pit file is a genuine samsung pit file so the worst that could happen is odin or the device will reject the pit file if it isnt signed.

Most likely just a rejection of the new PIT and a refusal to show any changes.

This signature may only be on specific models (I9300, I747, etc..) or it may be across all of them. I'll play with my I747M tomorrow and see if I can squeeze /system and expand /data.

From what I have seen so far, pit files for Galaxy S and Galaxy S II are not signed but the Galaxy S III pit files are signed which leads me to believe that this is something new Samsung has started doing and may continue to be the case for pit files on newer and upcoming devices.

The question is, will the signature be required to use the pit file or is it just to verify the file originated from samsung.

I need someone brave to open an untouched pit file for the S3 and hit the Save button without changing any values so it rewrites the pit file without the 256 byte signature and then test it in odin to see if it gets rejected or not.
