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

程序1:

<?php 
  
// Create a new imagick object 
$imagick = new Imagick(); 
  
// Create a image on imagick object 
$imagick->newImage(800, 250, 'black'); 
  
// Create a new imagickDraw object 
$draw = new ImagickDraw(); 
  
// Push the pattern 
$draw->pushPattern("MyPattern", 0, 0, 50, 50); 
$color = ['blue', 'black', 'cyan']; 
  
for ($x = 0; $x < 50; $x += 10) { 
    for ($y = 0; $y < 50; $y += 5) { 
        $draw->setFillColor($color[$y % 3]); 
        $draw->circle($x, $y + 80, $x % 2, $y); 
    } 
} 
  
// Pop the pattern 
$draw->popPattern(); 
  
// Set the fill Opacity 
$draw->setFillOpacity(0); 
  
// Set the fill pattern URL 
$draw->setFillPatternURL('#MyPattern'); 
  
// Draw a rectangle on which pattern is made 
$draw->rectangle(0, 0, 400, 400); 
  
// Render the draw commands 
$imagick->drawImage($draw); 
  
// Show the output 
$imagick->setImageFormat('png'); 
header("Content-Type:image/png"); 
echo $imagick->getImageBlob(); 
?>

輸出:

程序2:

<?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(); 
  
// Push the pattern 
$draw->pushPattern("MyPattern", 0, 0, 50, 50); 
  
for ($x = 0; $x < 50; $x += 10) { 
    for ($y = 0; $y < 50; $y += 5) { 
        $draw->rectangle($x, $y + 80, $x % 2, $y); 
    } 
} 
  
// Pop the pattern 
$draw->popPattern(); 
  
// Set the fill Opacity 
$draw->setFillOpacity(0); 
  
// Set the fill pattern URL 
$draw->setFillPatternURL('#MyPattern'); 
  
// Draw a rectangle on which pattern is made 
$draw->rectangle(0, 0, 900, 900); 
  
// Render the draw commands 
$imagick->drawImage($draw); 
  
// Show the output 
$imagick->setImageFormat('png'); 
header("Content-Type:image/png"); 
echo $imagick->getImageBlob(); 
?>
