how to rotate or flip a frame

[Altera_Forum]

Hello, 

 I´m working in a VIP suite megacore system, I´m using NIOS and SOPC builder and so far everything works fine.   I would like to make a rotation or flip to the picture, after checking all VIP components I can not find the way to do it.   In my opinion could not be difficult to do it in the frame buffer component, but I can not see the way to do it.  anybody did it??

U mean up becomes down or left becomes right ?

yes! 

 I need to make both.

flip shouldn't be too bad. its been discussed on the forum before, maybe as mirroring 

 rotate is going to be more difficult, you may need to use external memory with a custom frame buffer
