PHP | imagickdraw translate()函数
ImagickDraw::translate()函数是PHP中的一个内置函数,用于将平移应用于当前坐标系。它对当前坐标系应用平移,将坐标系原点移动到指定坐标。
句法:
bool ImagickDraw::translate( $x, $y )
参数:该函数接受上面提到的两个参数,如下所述:
- $x:这个参数用来保存x平移坐标的值。
- $y:这个参数用来保存y平移坐标的值。
返回值:此函数不返回任何值。
下面的程序说明了PHP中的ImagickDraw::translate()函数:
方案一:
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:
方案二:
setStrokeColor('black');
// Set the image filled color
$draw->setFillColor('red');
$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');
// Set the translation points
$draw->translate(10, 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);
// Set the image filled color
$draw->setFillColor('blue');
// Set the translation points
$draw->translate(10, 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);
// Set the image filled color
$draw->setFillColor('yellow');
// Set the translation points
$draw->translate(10, 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();
// Set the image dimensions
$image->newImage(400, 400, '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();
?>
