PHP ImagickDraw translate()用法及代码示例

ImagickDraw::translate()函数是PHP中的内置函数，用于将平移应用于当前坐标系。它将平移应用于当前坐标系，从而将坐标系原点移动到指定坐标。

用法:

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

参数：该函数接受上述和以下描述的两个参数：

$x:此参数用于保存x平移坐标的值。
$y:此参数用于保存y平移坐标的值。

返回值：该函数不返回任何值。

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

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(); 
?>

输出：
translate()
