我在 HTML 代码中使用图像，如下所示：

当我使用 wkhtmltopdf 将其转换为 PDF 时，某些 SVG 路径丢失。有人遇到过同样的问题吗？这个问题有一些解决方法吗？
我尝试在代码中使用相对路径、完整路径、base64 源和 SVG 本身（如示例中所示）。
wkhtmltopdf 版本：0.12.4
因此，这不是一个确切的解决方案，但现在更好的选择是使用chrome在无头模式下
$ chrome --headless --disable-gpu --print-to-pdf test.html
[0427/011400.636954:WARNING:dns_config_service_posix.cc(174)] dns_config has unhandled options!
[0427/011400.638406:ERROR:gpu_process_transport_factory.cc(1007)] Lost UI shared context.
[0427/011400.801881:INFO:headless_shell.cc(586)] Written to file output.pdf.
另外，如果你想更好地控制流程，你可以使用 NodeJS 和木偶师 https://github.com/GoogleChrome/puppeteer
const puppeteer = require('puppeteer');
(async () => {
const browser = await puppeteer.launch();
const page = await browser.newPage();
await page.goto('https://news.ycombinator.com', {waitUntil: 'networkidle2'});
await page.pdf({path: 'hn.pdf', format: 'A4'});
await browser.close();
})();
