以下示例程序旨在说明PHP中的ImagickDraw::pathFinish()函数：

示例1:

<?php 
  
// Create a new imagick object 
$imagick = new Imagick(); 
  
// Create a image on imagick object 
$imagick->newImage(800, 250, '#1a65f0'); 
  
// Create a new ImagickDraw object 
$draw = new ImagickDraw(); 
  
$draw->setFillColor('#2fceeb'); 
  
// Set the stroke color 
$draw->setStrokeColor('black'); 
  
// Set the stroke width 
$draw->setStrokeWidth(15); 
  
// Create a path 
$draw->pathStart(); 
$draw->pathMoveToAbsolute(50, 50); 
$draw->pathLineToAbsolute(100, 50); 
$draw->pathLineToRelative(0, 50); 
$draw->pathLineToHorizontalRelative(-50); 
$draw->pathFinish(); 
  
// Create another path 
$draw->pathStart(); 
$draw->pathMoveToAbsolute(50, 50); 
$draw->pathMoveToRelative(300, 0); 
$draw->pathLineToRelative(50, 0); 
$draw->pathLineToVerticalRelative(50); 
$draw->pathLineToHorizontalAbsolute(350); 
$draw->pathclose(); 
$draw->pathFinish(); 
  
// Render the draw commands 
$imagick->drawImage($draw); 
  
// Show the output 
$imagick->setImageFormat('png'); 
header("Content-Type: image/png"); 
echo $imagick->getImageBlob(); 
?>
