get rgb value of a color?

MoKaLux

hope you are all doing fine,

How can I get the rgb values of an hex color? Am I missing some gideros functions?

Thank you

MoKaLux

sorry I found it (thanks Rrraptor)

local function hex2rgb(hex) local r = (hex >> 16) / 255 local g = (hex >> 8 & 0xff) / 255 local b = (hex & 0xff) / 255 return r,g,b end

Peace!

If there is an alpha then you will also want to AND the r with 0xff too (like the g).

But if there is an alpha remember that lua ints are not always 32 bit (depending on the platform), so alpha may be corrupt anyway. But you can use int64 if required.

Or you can use ImGui

@hgy29 Yes, I meant if he just needed the red, it will be corrupted if there is an alpha, so he should mask it off.
