Greetings fellow Nim adventurers! Below you will find 16 handy Nim tips & tricks I came across while developing a medium-sized GUI program this year, Gridmonger (and related libraries). Some of them are about less known or undocumented Nim features or standard library functions, a few are workarounds for some rough edges of the language, and there’s also a handful of useful techniques I read about in forums or have invented on my own.

Not divide by two; you have to use the gamma transfer curve.

Looks like you missed all the other artifacts I gave examples for, which are all calibration independent (colour blending, compositing, rendering etc.)

More even = an even gradation from black to white.

If you read the article carefully, you'll realise that this is not just an optimisation (check for example the sections on colour blending and rendering; those artifacts are gamma calibration independent.)

Care to elaborate on the technical inaccuracies you spotted in the article? I would like to correct them, that's why I'm asking.

Thanks for the suggestion, I'll look into the scrset thing!

Yes, we need greater precision, ideally floats, but maybe 16 bits would be enough (haven't tested this or thought much about it.) But for multiple passes of processing floats are definitely the way to go due to rounding errors. I don't think you'd get worse performance when using floats on current hardware.
