What is PhpDig?
PhpDig is a PHP MySQL based
Web Spider & Search Engine.
imagefilledpolygon — Creates a filled poygon.
int imagefilledpolygon(image, points, vertices, color);
int image: Image
array points: Array of
int vertices: Number of
int color: Specified
Creates a filled polygon. The array specifying the
drawing coordinates must contain both the x and y
coordinates of each point in the polygon. For example,
array(100,100,125,125,150,150,200,200,100,100) would mean
that the first point is at 10,100, the second at 125,125,
and so on. The polygon must have at least three vertices
for the function to work; a good way to determine the
number of vertices is to count the array using count() and divide by two. A
point is made up of two values. If you used user input to
assign the polygon points, you can use the modulus
operator (%) to determine whether an even number of
values were given. Use imagepolygon() if you want to
create an unfilled polygon.
Example 418. Draw a red
$im = imagecreate(200, 200);
$green = imagecolorallocate($im, 0, 255, 0);
$red = imagecolorallocate($im, 255, 0, 0);
$points = array(100, 10, 150, 50, 160, 80, 10, 150, 100, 10);
$vertices = count($points) / 2;
imagefilledpolygon($im, $points, $vertices, $red);
