I'm using perl mod Gnome::ZvtTerm and want to change the defualt color
using $term->set_color_scheme($red, $green, $blue); The problem is no
matter how I plug-in the data I get this :\

need an array ref in set_color_scheme at zterm.pl line 518.

Can someone please show me a simple example to set the bg = black and
fg = white

Thanks,
-Russell

Hi Russ

Can you tell me how you plugged in the numbers?

Let me know if this works--thanks:

$red = [0x0000, 0xaaaa, 0x0000, 0xaaaa, 0x0000, 0xaaaa,
       0x0000, 0xaaaa, 0x5555, 0xffff, 0x5555, 0xffff,
       0x5555, 0xffff, 0x5555, 0xffff, 0xaaaa, 0x0];
 
$green = [0x0000, 0x0000, 0xaaaa, 0x5555, 0x0000, 0x0000,
         0xaaaa, 0xaaaa, 0x5555, 0x5555, 0xffff, 0xffff,
         0x5555, 0x5555, 0xffff, 0xffff, 0xaaaa, 0x0];
 
$blue = [0x0000, 0x0000, 0x0000, 0x0000, 0xaaaa, 0xaaaa,
        0xaaaa, 0xaaaa, 0x5555, 0x5555, 0x5555, 0x5555,
        0xffff, 0xffff, 0xffff, 0xffff, 0xaaaa, 0x0];
 
$term->set_color_scheme($red, $green, $blue);

Yes, that worked for me! Now I have some kind of realize() problem to
work out but I'm closer then ever before.

I don't mean to wast your time but could you please explain how this
sets the foreground = white and background = black. The reason is I
want the user to pick a color using the Gtk::ColorSelectionDialog and
I'm not sure how to do this yet.


Thanks for your time.

Hi Russ

I will type up a formal answer for you by the end of the day.

Basically the (hex value) array in $red, $green, $blue form 3-tuples--
if you read it in this order:

($red[0], $green[0], $blue[0])
($red[1], $green[1], $blue[1])
...

you will get

(0, 0, 0),
           (43690, 0, 0),
           (0, 43690, 0),
           (43690, 21845, 0),
           (0, 0, 43690),
           (43690, 0, 43690),
           (0, 43690, 43690),
           (43690, 43690, 43690),
           (21845, 21845, 21845),
           (65535, 21845, 21845),
           (21845, 65535, 21845),
           (65535, 65535, 21845),
           (21845, 21845, 65535),
           (65535, 21845, 65535),
           (21845, 65535, 65535),
           (65535, 65535, 65535),
           (43690, 43690, 43690),
           (0, 0, 0)

Each of the 3-tuples specify a color component as defined 
in gnome-terminal.c

Hi Russell

As previously mentioned in my clarification,

the arrays $red, $green, $blue defines the RGB color palletes in 3-tuples.

There are 18 elements [0 ... 17] in each array, for your purpose,
you're only concerned about the last two: elements 16 and 17.
Element 16 is the foreground and element 17 is the background.

So something like

           (65535, 65535, 65535), for element 16
and        
           (0, 0, 0), for element 17
 
translates into white on black.

In the sample I posted I used 

           (43690, 43690, 43690), for element 16.

You can try different values to see what works best for your terminal.

Hope this helps!

This was great answer to my question! Good response time too. I just
want to say thanks:)
