I don't believe the library supports rotation.

Yes, the library doesn't support rotation.
Is it due to the limitations of the RA8875? If not, is it possible to add it to the library?

Re: Rotation for RA8875 ?
I'm wondering is anyone has any thoughts on my previous post.
For my project, the 4.3" TFT display, http://www.adafruit.com/products/1591, and driver board RA8875, https://www.adafruit.com/products/1590, would work excellent.
However, I need to mount the display rotated 90 deg, which means all text and graphics will be portrait rather than landscape. If the RA8875 is not capable of 90 degree rotation, I'll need to re-think my project. The dimensions of the 4.3" TFT are almost perfect for my application.
Anyone have any ideas?

Re: Rotation for RA8875 ?
It seems that the chip itself supports font rotation, but we haven't actually tried it or have library code for it
For any remaining shapes, you'll have to adjust rotation in your software to account for it by doing the algebra to 'rotate' the coordinates!

Thank you for the reply.
Text rotation is mainly what I was concerned about.
I'll need to revisit my plans, and try to see if I can use the 3.5" TFT. http://www.adafruit.com/products/2050
Thanks again!
