Hi! Can someone help me to convert this JavaScript to Processing. I’m not so cool for this code yet, but I really need this function for my app. Thank you stranger!
Code:
/*
Sample Usage:
<script type="text/javascript" src="ntc.js"></script>
<script type="text/javascript">
var n_match = ntc.name("#6195ED");
n_rgb = n_match[0]; // This is the RGB value of the closest matching color
n_name = n_match[1]; // This is the text string for the name of the match
n_exactmatch = n_match[2]; // True if exact color match, False if close-match
alert(n_match);
</script>
*/
var ntc = {
init: function() {
var color, rgb, hsl;
for(var i = 0; i < ntc.names.length; i++)
{
color = "#" + ntc.names[i][0];
rgb = ntc.rgb(color);
hsl = ntc.hsl(color);
ntc.names[i].push(rgb[0], rgb[1], rgb[2], hsl[0], hsl[1], hsl[2]);
}
},
name: function(color) {
color = color.toUpperCase();
