the title. I basically need to make a script that will go through
every
possible color combination and print them to look just like (or
similar) to
the windows color picker. I need it in the format X-Y-Z. For example:
255-255-255
255-254-254
255-253-253
What I have so far is this:
***
?php
$break = printbr;
$n1 = 255;
$n2 = 12;
$n3 = 186;
$output = print
\$drawrect(\$get(color_x),\$get(color_y),\$get(color_w),\$get(color_h),brushColor-$n1-$n2-$n3
penColor-$n1-$n2-$n3)
\$button2(\$get(color_x),\$get(color_y),0,0,\$get(color_w),\$get(color_h),,,PVAR:SET:colorize_global:brushcolor-$n1-$n2-$n3
pencolor-$n1-$n2-$n3,TOOLTIP:\$n1-$n2-$n3\)
;
$output
?
***
The $drawrect, $button2, and $get are NOT php functions, but to be
printed
as actual text (which is why I have escaped them with the backslash).
Anyways, I thought it would be easiest to separate each R-G-B value
into its
own variable ($n1, $n2, and $n3). That way I could just use some code
(regex?) to cycle through the numbers 0 to 255.
The HARD part (that I can't seem to even think of a way to make it
possible)
is to change JUST the G and B values while keeping the R value at 255.
Then
when the G and B values both hit 0, the R value is set to 254 and
repeated
until it also hits 0 with the other two. I think (?) that will do
every
possible color? I also need to print each string with the individual
color
output, and I don't know how to do that either.
In short, I would like something that looks just like the windows
color
picker, and when each pixel of it is clicked, it will show me the
R-G-B
value in the format I would like.
If anyone understands what I am after,and could help, that would be
awesome!

HTML
a href=color.phpimg src=colormap.png ismap=ismap //a
PHP color.php
list($coords) = array_keys($_GET);
$coords = explode(',', $coords); // Easier way...?
$im = imagecreatefrompng('colormap.png');
$color = imagepixelat($im, $coords[0], $coords[1]);
I wouldn't do it like this, though. I'd use Javascript.

This is a very Bad Idea[tm], because it's going to generate
16,777,216 lines that the browser needs to receive, parse, and
display. This is going to be over 2,516,582,400 bytes (yes, 2.5GB!)
of data to be served. There are several better ways of doing it,
including using an HTML image map that has all of the colors laid-out
by pixel coordinates, reducing the number of colors you want to
display, using Flash, or any number of alternatives.
In any case, here's the code:
?php
if($_GET['r'] $_GET['g'] $_GET['b']) {
if(
!preg_match('/^[0-9]{1,3}$/',$_GET['r'])
|| !preg_match('/^[0-9]{1,3}$/',$_GET['g'])
|| !preg_match('/^[0-9]{1,3}$/',$_GET['b'])
) {
die('Incorrect parameters specified. Please try again.');
} else {
echo You chose the following:\n;
echo bR/b: .$_GET['r'].br /\n;
echo bG/b: .$_GET['g'].br /\n;
echo bB/b: .$_GET['b'].br /\n;
echo br /\n;
}
}
$newline = 63;
for($i=255;$i0;$i--) {
for($j=255;$j0;$j--) {
for($k=255;$k0;$k--) {
echo span
style=\background:rgb(.$i.,.$j.,.$k.);padding:0px;height=5px;width=5px;\;
echo a href=\?r=.$i.g=.$j.b=.$k.\;
echo
style=\color:rgb(.$i.,.$j.,.$k.);\X/a/span;
if($newline === 0) {
echo br /\n;
$newline = 63;
} else {
echo \n;
$newline--;
}
}
}
}
?
