Can someone tell me if I tweak the destination field in an arp request for TCP connection to match it with the the mac addresses of different recivers in an ethernet as the packet passes through them in short each one catches the arp request and replies, what would happen I mean will the sender of...

imagecolorclosestalpha
IMAGECOLORCLOSESTALPHA(3) 1 IMAGECOLORCLOSESTALPHA(3)imagecolorclosestalpha - Get the index of the closest color to the specified color + alphaSYNOPSIS
int imagecolorclosestalpha (resource $image, int $red, int $green, int $blue, int $alpha)
DESCRIPTION
Returns the index of the color in the palette of the image which is "closest" to the specified RGB value and $alpha level.
PARAMETERS
o $
image -An image resource, returned by one of the image creation functions, such as imagecreatetruecolor(3).
o $red
-Value of red component.
o $green
-Value of green component.
o $blue
-Value of blue component.
o $alpha
- A value between 0 and 127. 0 indicates completely opaque while 127 indicates completely transparent.
The colors parameters are integers between 0 and 255 or hexadecimals between 0x00 and 0xFF.
RETURN VALUES
Returns the index of the closest color in the palette.
EXAMPLES
Example #1
Search for a set of colors in an image
<?php
// Start with an image and convert it to a palette-based image
$im = imagecreatefrompng('figures/imagecolorclosest.png');
imagetruecolortopalette($im, false, 255);
// Search colors (RGB)
$colors = array(
array(254, 145, 154, 50),
array(153, 145, 188, 127),
array(153, 90, 145, 0),
array(255, 137, 92, 84)
);
// Loop through each search and find the closest color in the palette.
// Return the search number, the search RGB and the converted RGB match
foreach($colors as $id => $rgb)
{
$result = imagecolorclosestalpha($im, $rgb[0], $rgb[1], $rgb[2], $rgb[3]);
$result = imagecolorsforindex($im, $result);
$result = "({$result['red']}, {$result['green']}, {$result['blue']}, {$result['alpha']})";
echo "#$id: Search ($rgb[0], $rgb[1], $rgb[2], $rgb[3]); Closest match: $result.
";
}
imagedestroy($im);
?>
The above example will output something similar to:
#0: Search (254, 145, 154, 50); Closest match: (252, 150, 148, 0).
#1: Search (153, 145, 188, 127); Closest match: (148, 150, 196, 0).
#2: Search (153, 90, 145, 0); Closest match: (148, 90, 156, 0).
#3: Search (255, 137, 92, 84); Closest match: (252, 150, 92, 0).
