How to created a 'pixelated gradient'?

[Guest]

Hi,

I'm lookinf for help on how to create a pixelated gradeint (if that's the correct term!) in Ullustrator CS5. I will be using a country map outline as the 'boundary' or container for my graphic.

Below is a image I found on a stock website, which is basically what I want to do, but with only 2 colours. (though I'm assuming because it's a gradient I can changed them anyway). I've had a go with Live paint, which worked to some degree but it was incredibly time consuming and I have 20 or so graphics to do! Plus I want to minimise the lines as much as possible, which is not what is shows below.

Thanks for your help.

I would prepare it in Photoshop.

You will need to know how many tiles there are in order to generate a diffusion dithered bitmap which is applied as a layer mask in PS

Then make object mosaic from that in Illustrator

Hello.

How about creating it in pointillism style?

Something like this.

You need a map that has the desired coloring. Or just a map and then apply coloring with gradients or whatever you please.

Convert to a raster graphic.

Apply Object > Make Object Mosaic

Use the desired number of tiles (see documentation if you don't know how to use it)

Then ungroup (maybe twice, watch the layers panel)

Apply Effect > Convert to Shape > Ellipse (you need to set a low negative value)
