imagecolorexact - Get the index of the specified color
SYNOPSIS
int imagecolorexact (resource $image, int $red, int $green, int $blue)
DESCRIPTION
Returns the index of the specified color in the palette of the image.
If you created the image from a file, only colors used in the image are resolved. Colors present only in the palette are not resolved.
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.
RETURN VALUES
Returns the index of the specified color in the palette, or -1 if the color does not exist.
EXAMPLES
Example #1
Get colors from the GD logo
<?php
// Setup an image
$im = imagecreatefrompng('./gdlogo.png');
$colors = Array();
$colors[] = imagecolorexact($im, 255, 0, 0);
$colors[] = imagecolorexact($im, 0, 0, 0);
$colors[] = imagecolorexact($im, 255, 255, 255);
$colors[] = imagecolorexact($im, 100, 255, 52);
print_r($colors);
// Free from memory
imagedestroy($im);
?>
The above example will output something similar to:
Array
(
[0] => 16711680
[1] => 0
[2] => 16777215
[3] => 6618932
)
