Imagick::roundCorners

(PECL imagick 2.0.0)

Imagick::roundCorners — Rounds image corners

说明

Imagick::roundCorners ( 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。

参数

x_rounding: x rounding
y_rounding: y rounding
stroke_width: stroke width
displace: image displace
size_correction: size correction

范例

Example #1 Using Imagick::roundCorners():

Rounds the image corners


<?php

$image = new Imagick();
$image->newPseudoImage(100, 100, "magick:rose");
$image->setImageFormat("png");

$image->roundCorners(5,3);
$image->writeImage("rounded.png");
?>

返回值

成功时返回 TRUE。

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);
