Google chart map colors

[seth7f]

I've been trying to write a function co convert the color represented
in simple encoding to hex (or rgb values).

This is so I can create a legend for the map.

Does anyone have any suggestions? I've tried a couple of concepts but
my results have not even been close.

Eg.

// chco=ffffff,edf0d4,13390a

Function simple2hex($gradient_start, $gradient_end, $simple_value)
{
Return $hex_color;
}

$hex_color = simple2hex('ffffff', 'edf0d4', 'A');

Thanks for any help.

Seth,

Check out my tmMapLegend PHP 4 class. It interpolates colors to assist in generating a legend for the Google Charts API map chart type. It currently accepts simple or text encoded values and two or three color ramps and it returns a hex color or an array of hex colors.
