README

本项目实现了 Imagine 的接口，允许您对 SVG 图像进行简单修改。它在 Contao 中用于处理 SVG 图像的即时调整大小。

安装

php composer.phar require contao/imagine-svg

用法

use Contao\ImagineSvg\Imagine;
use Imagine\Image\Box;
use Imagine\Image\Point;

$imagine = new Imagine();

$imagine
    ->open('/path/to/image.svg')
    ->crop(new Point(50, 50), new Box(100, 100))
    ->resize(new Box(40, 40))
    ->save('/path/to/thumbnail.svg')
;

$image = $imagine->open('/path/to/image.svg');

$image->effects()
    ->gamma(1.5)
    ->negative()
    ->grayscale()
    ->colorize($color)
    ->sharpen()
    ->blur(2)
;

$image->save('/path/to/image.svg');

由于 SVG 图像的性质，getSize() 方法与其他实现略有不同。您可以通过以下示例检查返回值

use Contao\ImagineSvg\Imagine;
use Contao\ImagineSvg\SvgBox;

$imagine = new Imagine();
$size = $imagine->open('/path/to/image.svg')->getSize();

if (SvgBox::TYPE_NONE === $size->getType()) {
    // The image has no defined size
} elseif (SvgBox::TYPE_ASPECT_RATIO === $size->getType()) {
    // The image has a relative size, $size->getWidth() and $size->getHeight()
    // should be treated as an aspect ratio
} else {
    // The image has a defined size like a regular image
    // $size->getType() would return SvgBox::TYPE_ABSOLUTE in this case
}
