imagecolorresolve — Get the index of the specified color or its closest possible alternative

Description

int imagecolorresolve ( resource $image , int $red , int $green , int $blue )

This function is guaranteed to return a color index for a requested color, either the exact color or the closest possible alternative.

If you created the image from a file, only colors used in the image are resolved. Colors present only in the pallete are not resolved.

Parameters

image: An image resource, returned by one of the image creation functions, such as imagecreatetruecolor().
red: Value of red component.
green: Value of green component.
blue: Value of blue component.

Return Values

Returns a color index.

Examples

Example #1 Using imagecoloresolve() to get colors from an image

 <?php
// Load an image
$im = imagecreatefromgif('phplogo.gif');

// Get closest colors from the image
$colors = array();
$colors[] = imagecolorresolve($im, 255, 255, 255, 0);
$colors[] = imagecolorresolve($im, 0, 0, 200, 127);

// Output
print_r($colors);

imagedestroy($im);
?>

The above example will output something similar to:

  Array (     [0] => 89     [1] => 85 )
