Thankyou Ashley,
as I only need 5 colors for each image, my idea was to create a single pixel
image for each color and save it on the hd (so that i don't have to create
it every time).
I've finally used this code:
imagecopymerge($base, $img1, 0, 0, 1, 1, 100, 500, 75);
imagecopymerge($base, $img2, 100, 0, 1, 1, 100, 500, 75);
imagecopymerge($base, $img3, 200, 0, 1, 1, 100, 500, 75);
imagecopymerge($base, $img4, 300, 0, 1, 1, 100, 500, 75);
imagecopymerge($base, $img5, 400, 0, 1, 1, 100, 500, 75);
($imgX are 1*1 images. I have a function that checks if they exists)
You can see the output here: http://aagmns47.facebook.joyent.us/sdna/.
I think that copying a 1*1 image (and as said i'll cache all 1*1 colors on
the hd) on a background is less resource-expensive than creating a coloured
rectangle every time, isn't it?

Hi,
i've just started using GD libraries. My purpose is to create something like
a flag.
So that i have a 600*600 px background image, and a 1*1 px image for each
colour I need.
Ok now let's say i want to colour a third of the background image. I can use
this code:
imagecopymerge($base, $img1, 0, 0, 0, 0, 200, 600, 85);
It will simply make red first 200 px (on x axys) of the bg image. And this
work.
Now the problem is: how can i add another colour on pixels from 201 (201
right? not 200?) to 400?
Thankyou
Erm, why don't you use something like imagerectangle() ? It's far easier
and less resource intensive than having loads of single-pixel images for
each colour you want to use.
Thanks,
Ash
