我想使用SVG字符串创建一个矢量PDF。但是ImageMagick绘制函数总是返回"无法绘制图像"500错误。
$image = new 'Imagick();
$draw = new 'ImagickDraw();
$draw->setVectorGraphics('<root>'.$svg.'</root>');
$image->newImage(1052, 697, $bg);
$image->setColorspace('Imagick::COLORSPACE_CMYK);
$image->setImageResolution(300,300);
$image->setImageFormat('pdf');
$image->drawImage($draw);
file_put_contents('image.pdf', $image);
我尝试了简单的图纸，而不是从SVG源，这也不起作用。
希望有人能帮忙。由于
我的SVG:

我想知道你的SVG字符串是否与setVectorGraphics()兼容。我使用getVectorGraphics()与使用示例在这里在php.net imagickdraw setvectorgraphics，并使用的$SVG的结果，我能够使您的代码片段工作:
$svg = "<drawing-wand/><clip-path/><clip-units>Undefined</clip-units><decorate>None</decorate><encoding/><fill>#00000000FFFF</fill><fill-opacity>1</fill-opacity><fill-rule>Evenodd</fill-rule><font/><font-family/><font-size>12</font-size><font-stretch>Undefined</font-stretch><font-style>Undefined</font-style><font-weight>0</font-weight><gravity>Undefined</gravity><stroke>#FFFFFFFFFFFF</stroke><stroke-antialias>1</stroke-antialias><stroke-dasharray/><stroke-dashoffset>0</stroke-dashoffset><stroke-linecap>Butt</stroke-linecap><stroke-linejoin>Miter</stroke-linejoin><stroke-miterlimit>10</stroke-miterlimit><stroke-opacity>0</stroke-opacity><stroke-width>1</stroke-width><text-align>Undefined</text-align><text-antialias>1</text-antialias><text-undercolor>#000000000000</text-undercolor><vector-graphics>fill '#FFFF00000000'

$bg = new ImagickPixel("white");
$image = new 'Imagick();
$draw = new 'ImagickDraw();
$draw->setVectorGraphics("<root>$svg</root>");
$image->newImage(1052, 697, $bg);
$image->setColorspace('Imagick::COLORSPACE_CMYK);
$image->setImageResolution(300,300);
$image->setImageFormat('pdf');
$image->drawImage($draw);
file_put_contents('image.pdf', $image);
