I couldn't find any good color pickers for processing so I put together my own.

Might save someone an hour.

Hi julapy (and others).

I stumbled upon this very nice color picker of yours and am using it in one of my sketches.
I have added a small selector that indicates which color is currently selected.
However, I also would like to be able to set this selector from outside the class, with a function like: setColor(color new_color);

Unfortunately I have been unable to locate a color exactly in the image, maybe you, or someone else, has a solution for this?

Thanks in advance!

Remco

Not so cool method:
iterate through the whole image and stop when the pixel has the wanted color.

Good method:
write an inverse method of the "color-set-method" - but thats a little bit math Wink

That's what I tried, but when you scale the image this doesn't seem to work.

Now for the math Smiley Got any suggestions
