</div>
$data = json_encode($json,true);
$htmlData = htmlentities($data);
$htmlContent = htmlspecialchars_decode($htmlData);
另存为svg:
file_put_contents('assets/pdfs/new.svg',$htmlContent);
尝试在此处将我保存的svg转换为png,
$imPng = new \Imagick();
$png = file_get_contents('assets/pdfs/new.svg');
$png = '<?xml version="1.0" encoding="UTF-8" standalone="no"?>' .$png;
$imPng->readImageBlob($png);
$imPng->setimageFormat("png");
$imPng->writeImage('new.png');
file_put_contents ('assets/pdfs/new.png');
但是转换后的PNG为空白。我该怎么办 ?该代码有什么问题?
注意:在svg内容中,所有图像都以base64格式出现
