PHP | imagickdraw skewx()函数

ImagickDraw::skewX()函数是PHP中的一个内置函数,用于在水平方向倾斜当前坐标系。

句法:

bool ImagickDraw::skewX( $degrees )

参数:此函数接受单个参数$degrees ,该参数用于保存要倾斜的度数。

返回值:此函数不返回任何值。

下面的程序说明了PHP中的ImagickDraw::skewX()函数

方案一:

setFillColor('blue');
$points = [['x' => 40 * 5, 'y' => 10 * 5], 
           ['x' => 70 * 5, 'y' => 50 * 5], 
           ['x' => 60 * 5, 'y' => 15 * 5], ];
             
// Draw the polygon
$draw->polygon($points);
  
// Set the image filled color
$draw->setFillColor('red');
$draw->skewX(-60);
$points = [['x' => 40 * 5, 'y' => 10 * 5], 
           ['x' => 70 * 5, 'y' => 50 * 5], 
           ['x' => 60 * 5, 'y' => 15 * 5], ];
             
// Draw the polygon           
$draw->polygon($points);
   
// Set the image filled color
$draw->setFillColor('green');
$draw->skewX(30);
$points = [['x' => 40 * 5, 'y' => 10 * 5], 
           ['x' => 70 * 5, 'y' => 50 * 5], 
           ['x' => 60 * 5, 'y' => 15 * 5], ];
             
// Draw the polygon           
$draw->polygon($points);
  
// Create new Imagick object
$image = new Imagick();
$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:
歪斜X

方案二:

setStrokeColor('black');
  
// Set the filled color
$draw->setFillColor('red');
  
// Draw the circle
$draw->circle(250, 250, 100, 150); 
   
// Set the filled color
$draw->setFillColor('green');
  
// Set the skew of X
$draw->skewX(30);
  
// Draw the circle
$draw->circle(250, 250, 100, 150); 
   
// Set the filled color
$draw->setFillColor('yellow');
  
// Set the skew of X
$draw->skewX(30);
  
// Draw the circle
$draw->circle(250, 250, 100, 150); 
   
// Create new imagick object
$image = new Imagick();
  
// Create new image of given size
$image->newImage(900, 600, 'white');
  
// Set the image format
$image->setImageFormat("png");
  
// Draw the image
$image->drawImage($draw);
    
header("Content-Type: image/png");
  
// Display the output image
echo $image->getImageBlob();
?>

输出:
歪斜X
