Honestly? If you're good with the current approach, why change it.

That said, there's a LOT of repetition in there and while you probably _can_ improve that in this solution, a 'proper' language might be more readable. Again, if you're a C# developer, C#/F# (or even Powershell) scripts are probably ~closer to home~.

That whole script is basically - if I understand it correctly - two unrolled loops. Instead of two loops (logo dimensions, scale) you're duplicating a loooot of lines.

If this is no problem: Cool. Then again, maybe you want to improve this approach in the future?
