imagefilledpolygon — Draw a filled polygon

Description

Signature as of PHP 8.0.0 (not supported with named arguments)

imagefilledpolygon(GdImage $image, array $points, int $color): bool

Alternative signature (deprecated as of PHP 8.1.0)

imagefilledpolygon(
    GdImage $image,
    array $points,
    int $num_points,
    int $color
): bool

imagefilledpolygon() creates a filled polygon in the given image.

Parameters

image: A GdImage object, returned by one of the image creation functions, such as imagecreatetruecolor().
points: An array containing the x and y coordinates of the polygons vertices consecutively.
num_points: Total number of points (vertices), which must be at least 3.
If this parameter is omitted as per the second signature, points must have an even number of elements, and num_points is assumed to be count($points)/2.
color: A color identifier created with imagecolorallocate().

Return Values

Returns true on success or false on failure.

Changelog

Version	Description
8.1.0	The parameter `num_points` has been deprecated.
8.0.0	`image` expects a GdImage instance now; previously, a valid `gd` resource was expected.

Examples

Example #1 imagefilledpolygon() example


<?php
// set up array of points for polygon
$values = array(
            40,  50,  // Point 1 (x, y)
            20,  240, // Point 2 (x, y)
            60,  60,  // Point 3 (x, y)
            240, 20,  // Point 4 (x, y)
            50,  40,  // Point 5 (x, y)
            10,  10   // Point 6 (x, y)
            );

// create image
$image = imagecreatetruecolor(250, 250);

// allocate colors
$bg   = imagecolorallocate($image, 0, 0, 0);
$blue = imagecolorallocate($image, 0, 0, 255);

// fill the background
imagefilledrectangle($image, 0, 0, 249, 249, $bg);

// draw a polygon
imagefilledpolygon($image, $values, 6, $blue);

// flush image
header('Content-type: image/png');
imagepng($image);
imagedestroy($image);
?>

The above example will output something similar to:
