[Tig] semantics: definition vs. resolution

[Kevin Shaw]

My first post was a bit tongue in cheek, but
I think you made my point for me Jeff

I was quite specific in my post by defining 2k
>2K (the format being 2048 x 1556)

Whereas you DEFINED 2k as 2048 x 1107

So we can DEFINE 2k resolution as 2048 x 1556, or 2048 x 1108 (I have been
told that formats should consist of even numbers for technical reasons)

Therefore 2k is a resolution and 2048 x 1556 and 2048 x 1108 or indeed 2048
x 1107 are DEFINITIONS QED. :-)

Happy Coloring
