PHP ImagickDraw translate()用法及代碼示例

ImagickDraw::translate()函數是PHP中的內置函數，用於將平移應用於當前坐標係。它將平移應用於當前坐標係，從而將坐標係原點移動到指定坐標。

用法:

bool ImagickDraw::translate( $x, $y )

參數：該函數接受上述和以下描述的兩個參數：

$x:此參數用於保存x平移坐標的值。
$y:此參數用於保存y平移坐標的值。

返回值：該函數不返回任何值。

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

示例1:

<?php 
  
// require_once('path/vendor/autoload.php'); 
  
// Create a ImagickDraw object to draw into. 
$draw = new ImagickDraw(); 
  
// Set the stroke color 
$draw->setStrokeColor('black'); 
  
// Set the Image Filled Color 
$draw->setFillColor('red'); 
  
// Draw the circle 
$draw->circle(250, 250, 100, 150); 
   
// Set the Image Filled Color 
$draw->setFillColor('green'); 
  
// Set the translation points 
$draw->translate(90, 30); 
  
// Draw the circle 
$draw->circle(350, 350, 250, 350); 
   
// Create new imagick object 
$image = new Imagick(); 
  
// Set the dimensions of the image 
$image->newImage(500, 500, 'white'); 
  
// Set the image format 
$image->setImageFormat("png"); 
  
// Draw the image 
$image->drawImage($draw); 
header("Content-Type: image/png"); 
  
// Display the image 
echo $image->getImageBlob(); 
?>

輸出：
