HI, Vincent.
I just mofidied before and reverted again.
because some results are not correct.
However, I just found my build was something wrong.
It works fine now so i pushed again.
I don't know exactly why raster use those compuation
even the standard rotation fomular is there.
------------------------------------
Let's run together for the best moment!
-Regards, Hermet-
