imagepolygon

(PHP 4, PHP 5)

imagepolygon画一个多边形

说明

bool imagepolygon ( resource $image , array $points , int $num_points , int $color )

imagepolygon() 在图像中创建一个多边形。points 是一个 PHP 数组,包含了多边形的各个顶点坐标,即 points[0] = x0,points[1] = y0,points[2] = x1,points[3] = y1,以此类推。num_points 是顶点的总数。

Example #1 imagepolygon() 例子

<?php
// create a blank image
$image imagecreatetruecolor(400300);

// fill the background color
$bg imagecolorallocate($image000);

// choose a color for the polygon
$col_poly imagecolorallocate($image255255255);

// draw the polygon
imagepolygon($image,
             array (
                    
00,
                    
100200,
                    
300200
             
),
             
3,
             
$col_poly);

// output the picture
header("Content-type: image/png");
imagepng($image);

?>
