PHP | imagickdraw rotate()函数
ImagickDraw::rotate()函数是PHP的一个内置函数,用于将指定的旋转应用于当前坐标空间。
bool ImagickDraw::rotate( $degrees )
参数:此函数接受单个参数$degrees ,用于保存旋转度数的值。
返回值:此函数不返回任何值。
下面的程序说明了PHP中的ImagickDraw::rotate()函数:
方案一:
setStrokeOpacity(1);
// Set the stroke color
$draw->setStrokeColor('Green');
// Set the Fill Color
$draw->setFillColor('Red');
// Set the stroke width
$draw->setStrokeWidth(2);
// Draw the rectangle
$draw->rectangle(100, 200, 500, 400);
// Set the stroke color
$draw->setStrokeColor('black');
// Set the fill color
$draw->setFillColor('lightgreen');
// Set the rotation
$draw->rotate(10);
// Draw the rectangle
$draw->rectangle(100, 200, 500, 400);
//Create an imagick object
$imagick = new \Imagick();
// Set the image dimensions
$imagick->newImage(600, 500, 'White');
// Set the image format
$imagick->setImageFormat("png");
// Draw the image
$imagick->drawImage($draw);
header("Content-Type: image/png");
// Display the image
echo $imagick->getImageBlob();
?>
输出:
方案二:
setStrokeOpacity(1);
// Set the stroke color
$draw->setStrokeColor('Green');
// Set the Fill Color
$draw->setFillColor('Red');
// Set the stroke width
$draw->setStrokeWidth(2);
$smoothPointsSet = [
[ ['x' => 10.0 * 5, 'y' => 10.0 * 5],
['x' => 30.0 * 5, 'y' => 90.0 * 5],
['x' => 25.0 * 5, 'y' => 10.0 * 5],
['x' => 50.0 * 5, 'y' => 50.0 * 5], ]
];
foreach ($smoothPointsSet as $points) {
$draw->bezier($points);
}
// Set the stroke color
$draw->setStrokeColor('black');
// Set the fill color
$draw->setFillColor('lightgreen');
// Set the rotation angle
$draw->rotate(15);
foreach ($smoothPointsSet as $points) {
$draw->bezier($points);
}
// Create an imagick object
$imagick = new \Imagick();
// Set the image dimensions
$imagick->newImage(350, 350, 'White');
// Set the image format
$imagick->setImageFormat("png");
// Draw the image
$imagick->drawImage($draw);
header("Content-Type: image/png");
// Display the image
echo $imagick->getImageBlob();
?>
