    float $x_rounding,
    float $y_rounding,
    float $stroke_width = 10,
    float $displace = 5,
    float $size_correction = -6
): bool

Rounds image corners. The first two parameters control the amount of rounding and the three last parameters can be used to fine-tune the rounding process. 此方法在Imagick基于ImageMagick 6.2.9以上版本编译时可用。此方法在 Imagick 基于 ImageMagick 7.0.0 或以上版本编译时不可用。

参数

x_rounding: x rounding
y_rounding: y rounding

Alternative solution:
// example values
$width = 250;
$height = 250;
$cornerRadius = 10;

// create mask image
$mask = new Imagick();
$mask->newImage($width, $height, new ImagickPixel('transparent'), 'png');
// create the rounded rectangle
$shape = new ImagickDraw();
$shape->setFillColor(new ImagickPixel('black'));
$shape->roundRectangle(0, 0, $width, $height, $cornerRadius, $cornerRadius);
// draw the rectangle
$mask->drawImage($shape);
// apply mask
$image->compositeImage($mask, Imagick::COMPOSITE_DSTIN, 0, 0);
