IMAGECOLOREXACTALPHA(3) 1 IMAGECOLOREXACTALPHA(3)imagecolorexactalpha - Get the index of the specified color + alphaSYNOPSIS
int imagecolorexactalpha (resource $image, int $red, int $green, int $blue, int $alpha)
DESCRIPTION
Returns the index of the specified color+alpha in the palette of the image.
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 specified color+alpha in the palette of the image, or -1 if the color does not exist in the image's palette.
EXAMPLES
Example #1
Get colors from the GD logo
<?php
// Setup an image
$im = imagecreatefrompng('./gdlogo.png');
$colors = Array();
$colors[] = imagecolorexactalpha($im, 255, 0, 0, 0);
$colors[] = imagecolorexactalpha($im, 0, 0, 0, 127);
$colors[] = imagecolorexactalpha($im, 255, 255, 255, 55);
$colors[] = imagecolorexactalpha($im, 100, 255, 52, 20);
print_r($colors);
// Free from memory
imagedestroy($im);
?>
The above example will output something similar to:
Array
(
[0] => 16711680
[1] => 2130706432
[2] => 939524095
[3] => 342163252
)
