How to understand the cute::TiledCopy::tile2thrfrg function?

[admbbs]

There are only 5 lines of code but I just could not sort the transformation process out. Could anyone please elaborate on this a little bit? Thanks a lot!

are you having any issues in using tiled copies that is leading you to want to understand the internals?

Not so far, just out of curiosity.

Perhaps this question is too broad, I should narrow it down to more specific items.

Thanks for your reply anyway!

I believe I have figured this out. Thanks.
