以下示例程序旨在說明PHP中的ImagickDraw::popClipPath()函數:

程序1:

<?php

$imagick = new Imagick(); 
  
// Create a image on imagick object 
$imagick->newImage(800, 250, 'white'); 
  
// Create a new imagickDraw object 
$draw = new ImagickDraw();

// Push the clip path 
$draw->pushClipPath('testClipPath'); 
  
// This is the area which is going to be visible 
$draw->rectangle(0, 0, 250, 250); 
  
// Pop the clip path 
$draw->popClipPath(); 
  
// Set the clip path 
$draw->setClipPath('testClipPath'); 
  
// Draw a rectangle 
$draw->rectangle(50, 50, 350, 350); 
  
// Render the draw commands 
$imagick->drawImage($draw); 
  
// Show the output 
$imagick->setImageFormat('png'); 
header("Content-Type:image/png"); 
echo $imagick->getImageBlob(); 
?>

輸出:

<?php 
  
// Create a new imagick object 
$imagick = new Imagick(); 
  
// Create a image on imagick object 
$imagick->newImage(800, 250, 'white'); 
  
// Create a new imagickDraw object 
$draw = new ImagickDraw(); 
  
// Set font size 
$draw->setFontSize(60); 
  
// Push the clip path 
$draw->pushClipPath('testClipPath'); 
  
// This is the area which is going to be visible 
$draw->rectangle(0, 0, 250, 250); 
  
// Pop the clip path 
$draw->popClipPath(); 
  
// Set the clip path 
$draw->setClipPath('testClipPath'); 
  
// Annotate the text which is going to be clipped 
$draw->annotation(0, 150, 'Hello World'); 
  
// Render the draw commands 
$imagick->drawImage($draw); 
  
// Show the output
