hi list,
I'm trying to implement a color picker in one of my PD/GEM patches via TCL/tk (-lib Toxy). But as you can see in the example patch (attached) I need to convert the hex color values to RGB values. Now I was wondering if there is any object in some external which would do the job (conversion)?! Any hint would be more than welcome.
best regards gm

well tcl could do it, see -> http://wiki.tcl.tk/1067 , in python it' would be just int ('0xff', 16) so pyext might come in handy.

hi G_ M,
"winfo rgb ." is Tk's color name to rgb converter (for the root window's colormap). Since it fails if given an empty string, it should either be wrapped in a catch clause, or in a test, like this:
query set cl [tk_chooseColor] .: if .($cl != "".) .(winfo rgb . $cl.)
The tot's output is then a list of three 16-bit intensities, so they would probably need to be unpacked, and quantized with / 256 -> int.
