ImagickDraw::setStrokeLineJoin()函数是PHP中的内置函数,用于指定笔触路径时在拐角处使用的形状。
用法:
bool ImagickDraw::setStrokeLineJoin( $linejoin )
参数:该函数接受单个参数$linejoin,该参数用于将线连接的值保存为整数类型。
LINEJOIN constants:
- imagick::LINEJOIN_UNDEFINED(整数)
- imagick::LINEJOIN_MITER(整数)
- imagick::LINEJOIN_ROUND(整数)
- imagick::LINEJOIN_BEVEL(整数)
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::setStrokeLineJoin()函数:
程序1:
<?php
// require_once('path/vendor/autoload.php');
// Create an ImagickDraw object to draw into.
$draw = new \ImagickDraw();
// Set the stroke opacity
$draw->setStrokeOpacity(1);
// Set the stroke color
$draw->setStrokeColor('Black');
// Set the stroke opacity
$draw->setStrokeOpacity(0.8);
//Set the stroke width
$draw->setStrokeWidth(10);
// Set Stroke Line Join Parameteres
$draw->setStrokeLineJoin(Imagick::LINEJOIN_ROUND);
// Set the image filled color
$draw->setFillColor('lightgreen');
// Set the Stroke Miter Limit
$draw->setStrokeMiterLimit(40 * 12);
$points = [
['x' => 50 * 6, 'y' => 10 * 5],
['x' => 20 * 7, 'y' => 30 * 5],
['x' => 60 * 8, 'y' => 50 * 5],
['x' => 70 * 3, 'y' => 15 * 5],
];
// Draw the polygon
$draw->polygon($points);
// Create new Imagick object
$image = new \Imagick();
// Set the dimension of image
$image->newImage(500, 300, '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:
程序2:
<?php
// Create an ImagickDraw object
$draw = new ImagickDraw();
// Set the Stroke Width
$draw->setStrokeWidth(1);
// Set the Stroke Color
$draw->setStrokeColor('black');
// Set the image filled color
$draw->setFillColor('yellow');
// Set the Stroke Width
$draw->setStrokeWidth(20);
// Decalare the offset variable
$offset = 220;
$lineJoinStyle = [
\Imagick::LINEJOIN_MITER,
\Imagick::LINEJOIN_ROUND,
\Imagick::LINEJOIN_BEVEL,
];
for ($x = 0; $x < count($lineJoinStyle); $x++) {
$draw->setStrokeLineJoin($lineJoinStyle[$x]);
$points = [
['x' => 40 * 5, 'y' => 10 * 5 + $x * $offset],
['x' => 20 * 5, 'y' => 20 * 5 + $x * $offset],
['x' => 70 * 5, 'y' => 50 * 5 + $x * $offset],
['x' => 40 * 5, 'y' => 10 * 5 + $x * $offset],
];
// Draw the polygon
$draw->polyline($points);
}
// Create new Imagick object
$image = new \Imagick();
// Set the image dimensions
$image->newImage(500, 700, '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();
?>
