Color triplet conversion

[PhilHibbs]

Is there a function to break down a pixel colour into its RGB constituent values? Has anyone written a function to do this efficiently? Alternatively, is there a function that compares a colour with another using a tolerance like PixelSearch does?

HI,

you mean PixelGetColor ?

No, that returns the pixel colour value as a single number, I want to break that number down into its three RGB constituents, e.g. if the PixelGetColor function returns 0x010203 I want the 01, 02 and 03 as separate values, presumably a 3-value array would be the way to do this. I can code it myself as a series of modulus and divide operations, or as binary mask and shift operations if those are available in AutoIt, but if someone has already invesitgated the most efficient way of doing it then I'd rather re-use that work (i.e. I'm lazy).

This sort of operation would be considerably more efficient if implemented in C rather than in a scripting language.
