Vector polygon overlay in Sudoku Grab?

[Ian]

Hi Chris,

Forgive me if this isn't the right forum to ask this - I have searched
for a few days without any obvious answers, and this isn't directly
related to your image-processing library.

I'm particularly interested in the transparent polygon overlay you
have in Sudoku Grab. Is that done using Quartz 2D/Core Graphics, or
something else?

Many thanks for any pointers you may be able to offer.

Regards,

- Ian

Hi Ian,

I've replied to you directly, but yes it just use the standard core
graphics to
draw the polygon.

Cheers
Chris.
