how do i replace pixels colors with my own colors ?

69 New Member
Hi I am new to the GD library and am stuck on something and wondered if you could help me.

I am using PHP and GD.

I have an array with 40 predefined hexadecimal colors in it.

I have an image that is 6 x 6 pixles, and I would like to loop through the pixles, swapping the colours in the image for my predefined colors.

if say pixle 1 was already in my predefined colors i would like to leave it there and move to pixle no.2 else i would like to change that pixle in the image for the closest match that i have in my predefined colors.

i would like to loop through the whole image untill the last pixle is complete.

i have looked at imagecolorexact() , imagecolorresolve() imagecolorclostest(), and even a mix of all, but i cant get my head around the best way of doing it. please help :)
